[PATCH] x86-64: Fix preemption off of irq context with PREEMPT_BKL
Fixing the interrupt tst for CONFIG_PREEMPT on x86-64 exposes another
bug with CONFIG_PREEMPT_BKL. Calling schedule due to preemption
releases the BKL which it shouldn't do.
Call preempt_schedule_irq instead (like for i386). This fixes the
easily reproducible filesystem errors I've seen (with reiserfs, which
heavily relies on the BKL).

[PATCH] ext3: fix journal_unmap_buffer race
There is a race condition in jbd between journal_unmap_buffer() and
journal_commit_transaction(). This is leading to corruption of buffers on the
transaction's t_locked_list, leading to a variety of symptoms usually
involving an oops in kjournald.
The problem is that various special-case exit paths in journal_unmap_buffer()
call journal_put_journal_head without any locking. This is racing against a
refiling of the same journal_head in journal_commit_transaction():
__journal_unfile_buffer(jh);
__journal_file_buffer(jh, commit_transaction,
BJ_Locked);
The way these functions work, this leaves the jh temporarily with
b_transaction==NULL; and if journal_unmap_buffer()'s call to
journal_put_journal_head() hits this window, it sees the NULL transaction and
frees the journal_head which is just about to get refiled on the locked list.
The main exit path on journal_unmap_buffer() performs its
journal_put_journal_head() before dropping the j_list_lock, so is not
vulnerable to this race. The fix is to move the other similar calls on
special-case exit branches in that function so that they also release the
journal_head before dropping that lock.
This is low-risk since the new order has already been tested as the normal
exit path from this function. The change has had extensive testing and has
been shown to fix the problem with no regressions found.

[PATCH] ext3/jbd race: releasing in-use journal_heads
Fix destruction of in-use journal_head
journal_put_journal_head() can destroy a journal_head at any time as
long as the jh's b_jcount is zero and b_transaction is NULL. It has no
locking protection against the rest of the journaling code, as the lock
it uses to protect b_jcount and bh->b_private is not used elsewhere in
jbd.
However, there are small windows where b_transaction is getting set
temporarily to NULL during normal operations; typically this is
happening in
__journal_unfile_buffer(jh);
__journal_file_buffer(jh, ...);
call pairs, as __journal_unfile_buffer() will set b_transaction to NULL
and __journal_file_buffer() re-sets it afterwards. A truncate running
in parallel can lead to journal_unmap_buffer() destroying the jh if it
occurs between these two calls.
Fix this by adding a variant of __journal_unfile_buffer() which is only
used for these temporary jh unlinks, and which leaves the b_transaction
field intact so that we never leave a window open where b_transaction is
NULL.
Additionally, trap this error if it does occur, by checking against
jh->b_jlist being non-null when we destroy a jh.

[PATCH] Netmos parallel/serial/combo support
There's a bugzilla entry for this here:
http://bugzilla.kernel.org/show_bug.cgi?id=4334
This should fix all the problems I know about with Netmos combo cards:
- 9735, 9835, and 9855 are not supported
- combo cards with parallel are erroneously claimed by serial driver
- serial and parport_serial blindly probe for ports
parport_pc:
Sort Netmos device IDs, no functional change.
parport_serial:
Previously supported 9735 and 9835. Add 9745, 9845, 9855, and
add init hooks to discover how many serial/parallel ports are
actually present (the boards are available in various configs).
Add protection for overflow of static tables.
quirks:
Detect Netmos combo (parallel + serial) cards and change class from
SERIAL to OTHER to prevent serial driver from claiming them.
8250:
Add init hook to discover the number of serial ports present.
This prevents us from poking at unused BARs.
pci_ids:
Add Netmos 9745, 9845, and sort.

[PATCH] arch hook for notifying changes in PTE protections bits
Recently on IA-64, we have found an issue where old data could be used by
apps. The sequence of operations includes few mprotects from user space
(glibc) goes like this:
1- The text region of an executable is mmaped using
PROT_READ|PROT_EXEC. As a result, a shared page is allocated to user.
2- User then requests the text region to be mprotected with
PROT_READ|PROT_WRITE. Kernel removes the execute permission and leave
the read permission on the text region.
3- Subsequent write operation by user results in page fault and
eventually resulting in COW break. User gets a new private copy of the
page. At this point kernel marks the new page for defered flush.
4- User then request the text region to be mprotected back with
PROT_READ|PROT_EXEC. mprotect suppport code in kernel, flushes the
caches, updates the PTEs and then flushes the TLBs. Though after
updating the PTEs with new permissions, we don't let the arch specific
code know about the new mappings (through update_mmu_cache like
routine). IA-64 typically uses update_mmu_cache to check for the
defered flush flag (that got set in step 3) to maintain cache coherency
lazily (The local I and D caches on IA-64 are incoherent).
DavidM suggeested that we would need to add a hook in the function
change_pte_range in mm/mprotect.c This would let the architecture specific
code to look at the new ptes to decide if it needs to update any other
architectual/kernel state based on the updated (new permissions) PTE
values.
We have added a new hook lazy_mmu_prot_update(pte_t) that gets called
protection bits in PTEs change. This hook provides an opportunity to arch
specific code to do needful. On IA-64 this will be used for lazily making
the I and D caches coherent.

The provided patch fixes HPFS filesystem support under 64-bit Linux kernel

The problem is in 'time_t' size which is 8 bytes on 64-bit systems
(comparing to 4 bytes on 32-bit systems). The patch introduces local
'time32_t' type of the fixed size 4 and uses it where required.

[PATCH] io_remap_pfn_range: fix some callers for XEN
(from Keir:)
I have audited the drivers/ and sound/ directories. Most uses of
remap_pfn_range are okay, but there are a small handful that are
remapping device memory (mostly AGP and DRM drivers).
Of particular driver is the HPET driver, whose mmap function is broken even
for native (non-Xen) builds. If nothing else, vmalloc_to_phys should be used
instead of __pa to convert an ioremapped virtual address to a valid physical
address. The fix in this patch is to remember the original bus address as
probed at boot time and to pass this to io_remap_pfn_range.

[PATCH] io_remap_pfn_range: add for all arch-es
This patch introduces a new interface function for mapping bus/device memory:
io_remap_pfn_range. This accepts the same parameters as remap_pfn_range and
io_remap_page_range but should be used in any situation where the caller is
not simply remapping ordinary RAM. For example, when mapping device registers
the new function should be used.
The distinction between remapping device memory and ordinary RAM is critical
for the Xen hypervisor.
This patch series also cleans up the remaining users of io_remap_page_range
(in particular, the several sparc-specific sections in various drivers that
use a special form of io_remap_page_range: an extra <iospace> argument for
SPARC arch.) by converting them to use io_remap_pfn_range(), where
io_remap_pfn_range() supports passing <iospace> as part of the pfn argument.
The sparc32 & sparc64 code needs live testing.

[PATCH] ext2/3 file limits to avoid overflowing i_blocks
As discussed before, we can overflow i_blocks in ext2/ext3 inodes by
growing a file up to 2TB. That gives us 2^32 sectors of data in the file;
but once you add on the indirect tree and possible EA/ACL metadata,
i_blocks will wrap beyond 2^32. Consensus seemed to be that the best way
to avoid this was simply to stop files getting so large that this was a
problem in the first place; anything else would lead to complications if a
sparse file tried to overflow that 2^32 sector limit while filling in
holes.
I wrote a small program to calculate the total indirect tree overhead for
any given file size, and 0x1ff7fffe000 turned out to be the largest file we
can get without the total i_blocks overflowing 2^32.
But in testing, that *just* wrapped --- we need to limit the file to be one
page smaller than that to deal with the possibility of an EA/ACL block
being accounted against i_blocks.
So this patch has been tested, at least on ext3, by letting a file grow
densely to its maximum size permitted by the kernel; at 0x1ff7fffe000, stat
shows the file to have wrapped back exactly to 0 st_blocks, but with the
limit at 0x1ff7fffd000, du shows it occupying the expected 2TB-blocksize
bytes.

[PATCH] posix-cpu-timers and cputime_t divisons.
The posix cpu timers introduced code that will not work with an arbitrary
type for cputime_t. In particular the division of two cputime_t values
broke the s390 build because cputime_t is define as an unsigned long long.
The first problem is the division of a cputime_t value by a number of
threads. That is a cputime_t divided by an integer. The patch adds
another macro cputime_div to the cputime macro regime which implements this
type of division and replaces all occurences of a cputime / nthread in the
posix cpu timer code.
Next problem is bump_cpu_timer. This function is severly broken:
1) In the body of the first if statement a timer->it.cpu.incr.sched is
used as the second argument of do_div. do_div expects an unsigned long
as "base" parameter but timer->it.cpu.incr.sched is an unsigned long
long. If the timer increment ever happens to be >= 2^32 the result is
wrong and if the lower 32 bits are zero this even crashes with a fixed
point divide exception.
2) The cputime_le(now.cpu, timer->it.cpu.expires.cpu) in the else if
condition is wrong. The cputime_le() reads as "now.cpu <=
timer->it.cpu.expires.cpu" and the subsequent cputime_ge() reads as
"now.cpu >= timer.it.cpu.expires.cpu". That means that the two values
needs to be equal to make the body of the second if to have any effect.
The first cputime_le should be a cputime_ge.
3) timer->it.cpu.expires.cpu and delta in the else part of the if are of
type cputime_t. A division of two cputime_t values is undefined (think
of cputime_t as e.g. a struct timespec, that just doesn't work). We
could add a primitive for this type of division but we'd end up with a
64 bit division or something even more complicated.
The solution for bump_cpu_timer is to use the "slow" division algorithm
that does shifts and subtracts. That adds yet another cputime macro,
cputime_halve to do the right shift of a cputime value.
The next problem is in arm_timer. The UPDATE_CLOCK macro does the wrong
thing for it_prof_expires and it_virt_expires. Expanded the macro and
added the cputime magic to it_prof/it_virt.
The remaining problems are rather simple, timespec_to_jiffies instead of
timespec_to_cputime and several cases where cputime_eq with cputime_zero
needs to be used instead of "== 0".
What still worries me a bit is to use "timer->it.cpu.incr.sched == 0" as
check if the timer is armed at all. It should work but its not really
clean.

mems_generation is outofdate compared to the tasks cpuset mems_generation,
this mems_allowed update code needs to grap cpuset_sem, which can sleep.

[PATCH] cpusets: mems generation deadlock fix
The cpuset code to update mems_generation could (in theory) deadlock on
cpuset_sem if it needed to allocate some memory while creating (mkdir) or
removing (rmdir) a cpuset, so already held cpuset_sem. Some other process
would have to mess with this tasks cpuset memory placement at the same
time.
We avoid this possible deadlock by always updating mems_generation after we
grab cpuset_sem on such operations, before we risk any operations that
might require memory allocation.

[PATCH] New console flag: CON_BOOT
CON_BOOT is like early printk in that it allows for output really early on.
It's better than early printk because it unregisters automatically when a
real console is initialised. So if you don't get consoles registering in
console_init, there isn't a huge delay between the boot console
unregistering and the real console starting. This is the case on PA-RISC
where we have serial ports that aren't discovered until the PCI bus has
been walked.
I think all the current early printk users could be converted to this
scheme with a minimal amount of effort.

[PATCH] Fix irq_affinity write from /proc for ia64
Made GENERIC_HARDIRQ mechanism work for ia64 and CPU hotplug. When write
to /proc/irq is handled it is not appropriate to perform set_rte
immediatly, since there is a race when the interrupt is asserted while the
re-program is happening. Hence such programming is only safe when we do
the re-program at the time of servicing an interrupt. This got broken when
GENERIC_HARDIRQ got introduced for ia64.
- added CONFIG_PENDING_IRQ so default /proc/irq write handler can do the right
thing.
TBD: We currently dont handle redirectable hint either in the display, or
when we handle writes to /proc/irq/XX/smp_affinity. We need an arch
specific way to account for the presence of "r" hint when we handle the

[PATCH] break_lock fix
lock->break_lock is set when a lock is contended, but cleared only in
cond_resched_lock. Users of need_lockbreak (journal_commit_transaction,
copy_pte_range, unmap_vmas) don't necessarily use cond_resched_lock on it.
So, if the lock has been contended at some time in the past, break_lock
remains set thereafter, and the fastpath keeps dropping lock unnecessarily.
Hanging the system if you make a change like I did, forever restarting a
loop before making any progress. And even users of cond_resched_lock may
well suffer an initial unnecessary lockbreak.
There seems to be no point at which break_lock can be cleared when
unlocking, any point being either too early or too late; but that's okay,
it's only of interest while the lock is held. So clear it whenever the
lock is acquired - and any waiting contenders will quickly set it again.
Additional locking overhead? well, this is only when CONFIG_PREEMPT is on.
Since cond_resched_lock's spin_lock clears break_lock, no need to clear it
itself; and use need_lockbreak there too, preferring optimizer to #ifdefs.

[PATCH] Can't unmount bad inode
This patch fixes a problem when a inode which is the root of a mount
becomes bad (make_bad_inode()). In this case follow_link will return
-EIO, so the name resolution fails, and umount won't work. The
solution is just to remove the follow_link method from bad_inode_ops.
Any filesystem operation (other than unmount) will still fail, since
every other method returns -EIO.
A test case for this is:
1) export an smbfs on host A and mount the share on host B
2) create directory X on A under the exported directory
3) bind mount X to Y on B (Y need not be under the share)
4) remove directory X, and create regular file X (same name) on A
5) stat X on B, this will make X a bad inode (file type changed)
6) umount Y
Without the patch applied, umount won't succeed, and a reboot is
necessary to get rid of the mount.
With the patch applied, umount will succeed.
The same is true for any filesystem which uses make_bad_inode() to
mark an existing inode bad (NFS, SMBFS, FUSE, etc...).

[PATCH] uml: fix "cond. expr. as lvalues" warning
Gcc 3.4.3 (and probably any 3.4) emits some "deprecation" warnings currently
about usages of CHOOSE_MODE, since the below syntax has been deprecated:
(a ? foo: bar) = foobar;
which often results from expansion of:
CHOOSE_MODE(foo, bar) = foobar;
So add an additional __CHOOSE_MODE syntax for users which need to get a
lvalue, which uses (a ? &foo : &bar) inside a function, casts the result to
the correct type and dereference the pointer, and use it where needed (i.e.
in <sysdep/ptrace.h>)
The patch builds and runs correctly (this has been tested on i386 only, not on
x86_64), and removes all the warnings.

With Vadim Abrossimov <vadim_abrossimov@yahoo.com>
*) Handle USER_OBJS through the general Kbuild infrastructure; the trick we

This ain't at all worse than the previous kludgy solution, enables us to
use a better dependency handling and to support MODVERSIONS.
And it is UML-specific, as a bonus.
So, no "it ain't clean enough" reasoning is allowed to hold this patch
until you find a better solution. Leaving there the current broken code is
not accepted.

[PATCH] x86_64: Fix NMI RTC access race
Fix NMI RTC access race
This patch fixes a race between the CMOS clock setting and the NMI code. The
NMI code indiscriminatly sets index registers and values in the same place the
CMOS clock is set. If you are setting the CMOS clock and an NMI occurs, Bad
values could be written to or read from the CMOS RAM, or the NMI operation
might not occur correctly.
Resetting the NMI is not required on x86_64 (in fact, it should not be done
according to the ICH5 documentation). This patch simply removes the useless
code.

[PATCH] x86_64: Work around Tyan BIOS MTRR initialization bug.
Work around Tyan BIOS MTRR initialization bug.
Some Tyan AMD BIOS don't initialize the first fixed range MTRR, which causes
it to contain random bogus values. When the MTRR tries to duplicate the MTRR
state to other CPUs at startup it oopses because of this.
This patch works around this by catching exception while setting MTRRs.
It would be better to validate all fixed range MTRRs and fix them, but that
would be very complicated code. This simple hack seems to work too (except
that the first 64k of physical memory are likely uncached). A BIOS update
fixes that.

Since verify_area is going the way of the Dodo soon it seems resonable to
no longer refer to it in wrapper functions/macros. FPU_verify_area and
FPU_code_verify_area have already been converted to call access_ok so now
seems a good time to rename them. This patch makes no functional changes

[PATCH] x86: CMOS time update optimisation
This patch changes the update of the cmos clock to be timer driven rather
than poll driven by the timer interrupt function. If the clock is not
being synced to an outside source the timer is removed and thus system
overhead is nill in that case. The update frequency is still ~11 minutes
and missing the update window still causes a retry in 60 seconds.
We want the calls to sync_cmos_clock() to be made in a consistent environment.
This was not true when calling it directly from the NTP call code. The
change means that sync_cmos_clock() is ALWAYS called from run_timers(), i.e.
as a timer call back function.
Also, call the timer code only through the timer interface (set a short timer
to do it from the ntp call).

The numa code used to have to handle the fact that memory regions (as

node boundaries.
Since Mike's patch went in this doesn't happen anymore, because we iterate
over the memory regions from OF directly. This patch simply removes a
check that catered for the overlapping case, which now "can't happen".
The condition also happens to be broken in the current code, but in a
painless way, so it's as good as removed already.

[PATCH] ppc32/64: Map prefetchable PCI without guarded bit
While experimenting with framebuffer access performances, we noticed a very
significant improvement in write access to it when not setting the
"guarded" bit on the MMU mappings. This bit basically says that reads and
writes won't have side effects (it allows speculation). It appears that it
also disables write combining.
This patch implements a new phys_mem_access_prot() arch callback for use by
/dev/mem and fbdev when available, implements it for ppc32 and ppc64, and
modifies /dev/mem and fbdev to use it, respectively when available or on
ppc. I didn't change fbdev to use it on all archs when available because
there is already a whole lot of arch specific mess in there (more than in
/dev/mem !) that I didn't feel like messing with, but archs maintainers are
welcome to give it a go).
The old mechanism in /dev/mem is still there, but arch maintainers should
probably switch to this once which is more consistent imho.
Finally, the ppc32 and ppc64 implementation of this and of the PCI mmap
calls (used by /proc and /sys) are modified to check if the mapping happens
in a prefetchable PCI resource, in which case, the guarded bit is not set
for the pgprot. In fact, ppc32 implementation of this code is updated to
be identical to ppc64.
This improves framebuffer write performance on a simple test paul wrote
from about 50Mb/sec to 200Mb/sec on my M9 based laptop and on a G5. The
new hook will automatically catch up Xfree mmap's from /dev/mem, so it will
work out of the box with existing X servers. Kernel fbdev accesses aren't
improved yet as ioremap doesn't use that mecanism.

[PATCH] ppc32: Fix Sandpoint Soft Reboot
This patch allows the Freescale Sandpoint to perform soft reboots. A write
of 0x00 to the Winbond's Chip Select Control Register was clearing the
Upper BIOS Chip Select Enable bit which unmaps the boot flash. The comment
associated with the write noted that it was enabling the RTC and Keyboard
address locations, but the bits in question (1 and 0) are reserved when the
Winbond chip is in PowerPC mode. Also, the bits are 1 for enable, 0 for
disable, therefore the original code was actually disabling the address
locations. The patch also corrects errors in the definitions of 2
configuration bits in the Tundra Tsi107 bridge's MAPB Options register.

filemap_nopage has the following code:
retry_all:
size = (i_size_read(inode) + PAGE_CACHE_SIZE - 1) >> PAGE_CACHE_SHIFT;

goto outside_data_content;
/* If we don't want any read-ahead, don't bother */

/*
* The "size" of the file, as far as mmap is concerned, isn't bigger
* than the mapping
*/
if (size > endoff)
size = endoff;
After this, size is not referenced. So, either this potential reassignment
of size is superfluous, or we are missing some other code later on in the
function. If it is the former, I've attached a patch which will remove the
code.

which are obsoleted (duplicated) by including linux/mm.h (and friends)
They are double checked and verified by the PLM cross compiling service
(the patched kernel gives the same warnings/errors as the unpatched)

[PATCH] slab shrinkers: use vfs_cache_pressure
Fix some bugs spotted by Andrea Arcangeli <andrea@suse.de>
- When we added /proc/sys/vm/vfs_cache_pressure we forgot to allow it to
tune the dquot and mbcache slabs as well.
- Reduce lock contention in shrink_dqcache_memory().
- Use dqstats.free_dquots in shrink_dqcache_memory(): this is the count of
reclaimable objects.
- Export sysctl_vfs_cache_pressure to GPL modules for mbcache.o

[PATCH] mm counter operations through macros
This patch extracts all the operations on counters protected by the page
table lock (currently rss and anon_rss) into definitions in
include/linux/sched.h. All rss operations are performed through the
following macros:
get_mm_counter(mm, member) -> Obtain the value of a counter
set_mm_counter(mm, member, value) -> Set the value of a counter
update_mm_counter(mm, member, value) -> Add to a counter
inc_mm_counter(mm, member) -> Increment a counter
dec_mm_counter(mm, member) -> Decrement a counter
With this patch it becomes easier to add new counters and it is possible to
redefine the method of counter handling. The counters are an issue for
scalability since they are used in frequently used code paths and may cause
cache line bouncing.
F.e. One may not use counters at all and count the pages when needed, switch
to atomic operations if the mm_struct locking changes or split the rss
into counters that can be locally incremented.
The relevant fields of the task_struct are renamed with a leading underscore
to catch out people who are not using the acceessor macros.

[PATCH] slab.[ch]: kmalloc() cleanups
I found a new idea for optimizing the loop in kmalloc - now the cleanup
both reduces the size of the .text segment in mm/slab.o and speeds up largs
kmallocs a bit. I still loose 2 cycles for kmalloc(32,GFP_KERNEL) compared
to the current code, but I haven't figured out how I could optimize
further.
- inline kmem_find_general_cachep()
- optimize kmem_find_general_cachep() and document the optimization.
- remove duplicate code from __kmalloc(): call kmem_find_general_cachep()
directly.

[PATCH] ppc64: fix AIO panic on PPC64 caused by is_hugepage_only_range()
When testing AIO on PPC64 (a power5 machine) running 2.6.11 with
CONFIG_HUGETLB_PAGE=y, I ran into a kernel panic when a process exits that has
done AIO (io_queue_init()) but has not done the io_queue_release(). The
exit_aio() code is cleaning up and panicking when trying to free the aio ring
buffer.
I tracked this down to is_hugepage_only_range() (include/asm-ppc64/page.h)
which is doing a touches_hugepage_low_range() which is checking
current->mm->context.htlb_segs. The problem is that exit_mm() cleared tsk->mm
before doing the mmput() which leads to the exit_aio() and then the panic.
Looks like is_hugepage_only_range() is only used in ia64 and ppc64. Fix is to
change is_hugepage_only_range() to take an 'mm' as a parameter as well as
'addr' and 'len' and then the ppc64 code could change to use 'mm'. It looks
like it has been broken for quite a while.

[PATCH] pcmcia: don't send eject request events to userspace
Here follow PCMCIA-related patches which allow for kernel-based matching
between 16-bit PCMCIA devices and their drivers. If you're using this (and
using a special startup script or small tool), you don't need to run "cardmgr"
any longer. cardmgr still works, though, allowing for a gradual transition.
These patches apply on top of what's in 2.6.11-rc4-mm1; for proper operation
pcmcia-bridge-resource-management-fix.patch should be removed first, though.
Andrew, please apply them to your next -mm release.
1. Theory of operation I: setting up the sockets
================================================
- the appropriate socket driver is initialized (modprobe or built-in)
- a hotplug event (CLASS=pcmcia_socket) is generated
- if it's a socket which doesn't map the resources statically, resources
available for use by PCMCIA cards need to be marked as "allowed". This is
done using either a small shell script[*] or pcmcia-socket-startup[**]. The
latter parses /etc/pcmcia/config.opts -- the same file cardmgr currently
uses for this purpose.
[*] e.g.
#!/bin/sh
echo -n "+ 0x00000100 - 0x000004cf" > /sys/class/pcmcia_socket/pcmcia_socket1/available_resources_io
echo -n "+ 0x60000000 - 0x60ffffff" > /sys/class/pcmcia_socket/pcmcia_socket1/available_resources_mem
echo -n "1" > /sys/class/pcmcia_socket/pcmcia_socket1/available_resources_setup_done
[**] note: for pcmcia-socket-startup to work properly you need a patch for
libsysfs (it is already accepted by the maintainer of the package). See
below for details.
2. Theory of operation II: setting up a device
==============================================
- a pcmcia device is discovered in the socket
- device information is determined and exported to sysfs
- a hotplug event is created, passing -- among others -- a complete MODNAME
string to userspace. Available match flags are the product ID strings [in
userspace, only the hashes are matched -- you can't use strings in
modules.alias], manufactor and card ID, the multifunction device number,
the pseudo-multifunction device number [this is what e.g.
bind "serial_cs", bind "serial_cs"
was before], whether it needs a CIS override, and the function ID [this match
is only used if it is allowed by userspace -- it should be avoided and will
be removed in future, after existing users have been converted to matches of
other types].
- modprobe $MODNAME [*]
- the device is matched against drivers. function ID matches are ignored at
this stage. If the device needs a CIS override, it is requested from
userspace using the firmware helpers. It is recommended to have a symlink
either from /lib/firmware/cis/ to /etc/pcmcia/cis/ or the other way to let
both (old) cardmgr and (new) firmware.agent access the override CIS data.
- if no driver was found, an userspace helper checks whether the card is one of
two(!) which can only be detected using cardmgr's tuple directive. If this is
the case, a CIS override is done using
/sys/class/pcmcia_socket/pcmcia_socket%n/cis , loading a CIS with proper
identification values.
- if this doesn't lead to a driver being bound to the device, function ID-based
matches are allowed.
[*] note: for this to work properly you need a patch to be written which loads
_all_ matching modules, not just one]
3. patches
==========
I'll not send the patches which add the proper device identification tables to
this list, but only (and a bit later) to Andrew and the appropriate
maintainers. You can find them already at
http://www.kernel.org/pub/linux/kernel/people/brodo/patches/2.6.11-rc5/
-- they start with pcmcia-25-
I used all identification information I could find in pcmcia-cs, the kernel,
and some web resources and, but probably missed some. If I did, please send
me either the appropriate device info from the cardmgr config file or the
output of "pcmcia-modalias" (see below) -- or a PCMCIA_MATCH patch.
4. userspace tools
==================
Several GPL[*] userspace tools are required or useful for this (new) method of
operation. I'll send them to this list for review, and they're also available
_temporarily_ at
http://www.kernel.org/pub/linux/kernel/people/brodo/temp-pcmcia-tools.tar.gz
I'm still undecided on what to do with these userspace tools. IMO they could
either be merged into pcmcia-cs or distributed in addition to pcmcia-cs. Also,
I'd be very glad if somebody else could maintain and improve these tools.
pcmcia-socket-startup
This tool is based on "cardmgr" by Dave Hinds, but most of it was removed. The
remains parse the /etc/pcmcia/config file for allowed ioport and iomem ranges
and for disallowed IRQs, and sets these using libsysfs. Due to a bug in
libsysfs, a patch is needed for this to work properly. It takes one parameter,
the socket number to be set up.
pcmcia-modalias
This tool reads device information and generates a MODALIAS string just like
the kernel exports using hotplug for this device. It takes one paramter, the
device's bus_id string (e.g. "pcmcia-modalias 1.0" for the first device on the
second PCMCIA socket)
pcmcia-check-broken-cis
This checks whether the CIS is so broken that only the "tuple"-based match is
possible. It takes one parameter, the socket the PCMCIA card to be tested is
inserted to, and returns nothing (if no CIS override is needed), or the CIS
file name. The CIS parsing is done using a much simplified version of what
is to be found in drivers/pcmcia/cistpl.c, so this is based on Dave Hinds
work as well.
hotplug/pcmcia*
The hotplug scripts are quite self-explanatory and also allow for "coldplug"
(i.e. they work around "missed" events during boot).
pccardctl
This previously announced tool uses sysfs instead of an ioctl for commands
like "eject", "insert", "info" and "ident".
[*] reason: they're partly based on other GPL-licensed tools.
This patch:
Don't inform cardmgr of ejection requests so that "cardctl eject" behaves
_exactly_ the same as a physical ejection from an userspace point of view.
Removing this allows us to clean up some other code which is otherwise unused.

[ARM] Fix ARM TLB shootdown code
We missed flushing the TLB when we're unmapping only reserved pages.
Since the kernel is now better at passing vmas which correspond
solely with the region to unmap, we can use tlb_*_vma() to do
"just enough" flushing, both for the TLB and cache.
We can avoid all flushes in tlb_*_vma() for the full-MM case, and
just do a flush_tlb_mm(). We can omit the cache flushing because
this thread will die soon.

[ARM PATCH] 2576/1: Fix LDRD and LDRSB (Thumb) abort handling
Patch from Deepak Saxena
The ARM LDRD (v5+) and Thumb LDRSB instructions use bit 20/11 (ARM/Thumb)
differently than every other instruction, so it is set to 0 (write) even
though the instructions are read instructions. This means that during an
abort the instructions will be treated as a write and the handler will
raise a signal from unwriteable locations if they fault. We have to
specifically check for these instructions from the abort handlers to
treat them properly. EABI toolchains emit LDRD instructions and even
those not using EABI might have handcoded ASM that uses these instructions.
This patch creates an abort-macro.S file that is included by the
abort-ev* files that need the special cases and changes those
handlers to use the macros. ARMv6 does not need the special case
handling as the HW takes care of setting the FSR bit appropriately.

[ARM PATCH] 2579/1: make early boot failure more verbose
Patch from Nicolas Pitre
It is pointless for cases where one tries to boot a kernel
on the wrong ARM subarchitecture, but for those cases where the
architecture is similar enough so the low level routines do work
then something a bit more informative than "Error: a" might be
handy, especially when the bootloader is the culprit.
All extra strings are compiled in only if CONFIG_DEBUG_LL
is selected of course.

A couple of fixes to the ColdFire specific trap handling code:

breaks return stack badly if applications work with stack un-aligned.
. use generated asm-offsets instead of local offset definitions
. use THREAD_SIZE definition instead of hard coding stack size
(this is needed to support 4k stacks)
. some instruction optimization (uses instructions that encode using
ledd bytes)

[PATCH] ppc64: introduce pSeries_reconfig.[ch]
Move as much pSeries-specific DLPAR/hotplug code as possible into its own
file, which is built only when pSeries support is enabled in the config. This
new file is intended to contain support code for the "Dynamic Reconfiguration"
option in the RISC Platform Architecture, which encompasses both PCI hotplug
and dynamic logical partitioning (DLPAR).
This patch mostly just moves code around, but the device node addition and
removal API is slightly modified. In this way, of_add_node and of_remove_node
are now responsible only for safely updating the device tree and global list,
without all the other stuff like proc entries etc. of_add_node and
of_remove_node have been renamed to of_attach_node and of_detach_node,
respectively.
This also adds the definitions and api for a notifier chain which is meant to
be used by code that must act upon device node addition or removal. Patches
to migrate code to the notifier api follow in this series.

[PATCH] ppc64: make OF node fixup code usable at runtime
At boot we recurse through the device tree "fixing up" various fields and
properties in the device nodes. Long ago, to support DLPAR and hotplug, we
largely duplicated some of this fixup code, the main data structures which are
attached to the new device nodes.
This patch introduces a helper function (prom_alloc) for handling allocations
at both boot and runtime, kills most of the duplicated code, and makes
finish_node, finish_node_interrupts, and interpret_pci_props suitable for use
at runtime by converting them to use prom_alloc.

[PATCH] ppc64: preliminary changes to OF fixup functions
Preliminary modifications to support using some of the interpret_func family
of functions at runtime. Changes the mem_start argument to be passed by
reference, and the return type to int for error handling to be implemented in
following patches.
