[IA64] SGI Altix hardware performance monitoring API
The SGI Altix PROM supports a SAL call for performance monitoring and for
exporting NUMA topology. We need this in community kernels for diagnostic
and performance tools to use, especially on very large machines.
This patch registers a dynamic misc device "sn_hwperf" that supports an
ioctl interface for reading/writing memory mapped registers on Altix
nodes and routers via the new SAL call. It also creates a read-only
procfs file "/proc/sgi_sn/sn_topology" to export NUMA topology and Altix
hardware inventory.
> What tools are using this?
Performance Co-Pilot http://oss.sgi.com/projects/pcp in particular,
pmshub, shubstats and linkstat. Numerous other users include anything
that needs knowledge of numa topology/interconnect in order to perform
well, e.g. mpt. BTW I have not exported any API functions .. at this
point I don't think we need any modules to call the API.

Fixes slab corruption in cbq_destroy. cbq_destroy_filters and

[IPSEC]: Implement DSCP decapsulation
This patch adds DSCP decapsulation for IPsec. This is enabled by

maintains compatibility and is also good for performance reasons.

encapsulating the DSCP can and should be done by netfilter.

When sending NA in response to NS, we may not know the

[PATCH] matroxfb update + sparse annotations
This change switches matroxfb on x86 and x86_64 from dereferencing
pointers to {read,write}[bwl], as __pa() are gone from them, and so gcc
does not need an additional register for preserving address between
consecutive {read,write}[bwl].
Then it switches only supported architecture left (ppc/ppc64/arm) from
dereferencing pointers to __raw_{read,write}[bwl].
Third part is fixing sparse complaints: add __iomem here and there, and
switch one 1bit bitfield from int to unsigned int.
After this there should be no sparse complaints in matroxfb.

[PATCH] back out siginfo_t.si_rusage from waitid changes
As I explained in the waitid patches, I added the si_rusage field to
siginfo_t with the idea of having the siginfo_t waitid fills in contain all
the information that wait4 or any such call could ever tell you. Nowhere
in POSIX nor anywhere else specifies this field in siginfo_t.
When Ulrich and I hashed out the system call interface we wanted, we looked
at siginfo_t and decided there was plenty of space to throw in si_rusage.
Well, it turns out we didn't check the 64-bit platforms. There struct
rusage is ridiculously large (lots of longs for things that are never in a
million years going to hit 2^32), and my changes bumped up the size of
siginfo_t. Changing that size is more trouble than it's worth.
This patch reverts the changes to the siginfo_t structure types,
and no longer provides the rusage details in SIGCHLD signal data.
Instead, I added a fifth argument to the waitid system call to fill in rusage.
waitid is the name of the POSIX function with four arguments. It might
make sense to rename the system call `waitsys' to follow SGI's system call
with the same arguments, or `wait5' in the mindless tradition. But, feh.
I just added the argument to sys_waitid, rather than worrying about
changing the name in all the tables (and choosing a new stupid name).

[IPV4]: Make fib_semantics algorithms scale better.
A singly linked list was previously used to
do fib_info object lookup for various actions
in the routing code. This does not scale very
well with many devices and even a moderate number
of routes. This was noted by Benjamin Lahaise.
To fix all of this we use 3 hash tables, two of
which grow dynamically as the number fib_info
objects increases while the final one is fixes in
size.
The statically sized table hashes on device index.
This is used for fib_sync_down, fib_sync_up, and
ip_fib_check_default.
The first dynamically sized table is keyed on
protocol, prefsrc, and priority. This is used
by fib_create_info() to look for existing fib_info
objects matching the new one being constructed.
The last dynamically sized table is keyed on
the preferred source of the route if it has one
specified. This is used by fib_sync_down when
a local address disappears.
There are still some scalability problems for
Bens test case in fib_hash.c and I will try to
attack those next.

[PATCH] uml: fix scheduler race
This fixes a use-after-free bug in the context switching. A process going
out of context after exiting wakes up the next process and then kills
itself. The problem is that when it gets around to killing itself is up to
the host and can happen a long time later, including after the incoming
process has freed its stack, and that memory is possibly being used for
something else.
The fix is to have the incoming process kill the exiting process just to
make sure it can't be running at the point that its stack is freed.

[PATCH] HVCS fix to replace yield with tty_wait_until_sent in hvcs_close
Following the same advice you gave in a recent hvc_console patch I have
modified HVCS to remove a while() { yield(); } from hvcs_close() which may
cause problems where real time scheduling is concerned and replaced it with
tty_wait_until_sent() which uses a real wait queue and is the proper method
for blocking a tty operation while waiting for data to be sent. This patch
has been tested to verify that all the paths of code that were changed were
hit during the code run and performed as expected including hotplug remove
of hvcs adapters and hangup of ttys.
- Replaced yield() in hvcs_close() with tty_wait_until_sent() to prevent
possible lockup with realtime scheduling.
- Removed hvcs_final_close() and reordered cleanup operations to prevent
discarding of pending data during an hvcs_close() call.
- Removed spinlock protection of hvcs_struct data members in
hvcs_write_room() and hvcs_chars_in_buffer() because they aren't needed.

[PATCH] Add prctl to modify current->comm
This patch adds a prctl to modify current->comm as shown in /proc. This
feature was requested by KDE developers. In KDE most programs are started by
forking from a kdeinit program that already has the libraries loaded and some
other state.
Problem is to give these forked programs the proper name. It already writes
the command line in the environment (as seen in ps), but top uses a different
field in /proc/pid/status that reports current->comm. And that was always
"kdeinit" instead of the real command name. So you ended up with lots of
kdeinits in your top listing, which was not very useful.
This patch adds a new prctl PR_SET_NAME to allow a program to change its comm
field.
I considered the potential security issues of a program obscuring itself with
this interface, but I don't think it matters much because a program can
already obscure itself when the admin uses ps instead of top. In case of a
KDE desktop calling everything kdeinit is much more obfuscation than the
alternative.

[PATCH] shmem: avoid the shmem_inodes list
If we're thinking about shmem scalability... isn't it silly that each shmem
object is added to the shmem_inodes list on creation, and removed on deletion,
yet the only use for that list is in swapoff (shmem_unuse)?
Call it shmem_swaplist; shmem_writepage add inode to swaplist when first swap
allocated (usually never); shmem_delete_inode remove inode from the list after
truncating (if called before, inode could be re-added to it).
Inode can remain on the swaplist after all its pages are swapped back in, just
be lazy about it; but if shmem_unuse finds swapped count now 0, save itself
time by then removing that inode from the swaplist.

[PATCH] shmem: no sbinfo for tmpfs mount?
Some might want a tmpfs mount with the improved scalability afforded by
omitting shmem superblock accounting; or some might just want to test it in an
externally-visible tmpfs mount instance.
Adopt the convention that mount option -o nr_blocks=0,nr_inodes=0 means
without resource limits, and hence no shmem_sb_info. Not recommended for
general use, but no worse than ramfs.
Disallow remounting from unlimited to limited (no accounting has been done so
far, so no idea whether it's permissible), and from limited to unlimited
(because we'd need then to free the sbinfo, and visit each inode to reset its
i_blocks to 0: why bother?).

[PATCH] shmem: no sbinfo for shm mount
SGI investigations have shown a dramatic contrast in scalability between
anonymous memory and shmem objects. Processes building distinct shmem objects
in parallel hit heavy contention on shmem superblock stat_lock. Across 256
cpus an intensive test runs 300 times slower than anonymous.
Jack Steiner has observed that all the shmem superblock free_blocks and
free_inodes accounting is redundant in the case of the internal mount used for
SysV shared memory and for shared writable /dev/zero objects (the cases which
most concern them): it specifically declines to limit.
Based upon Brent Casavant's SHMEM_NOSBINFO patch, this instead just removes
the shmem_sb_info structure from the internal kernel mount, testing where
necessary for null sbinfo pointer. shmem_set_size moved within CONFIG_TMPFS,
its arg named "sbinfo" as elsewhere.
This brings shmem object scalability up to that of anonymous memory, in the
case where distinct processes are building (faulting to allocate) distinct
objects. It significantly improves parallel building of a shared shmem object
(that test runs 14 times faster across 256 cpus), but other issues remain in
that case: to be addressed in later patches.

[PATCH] shmem: inodes and links need lowmem
Keith Mannthey's Bugzilla #3268 drew attention to how tmpfs inodes and
dentries and long names and radix-tree nodes pin lowmem. Assuming about 1k of
lowmem per inode, we need to lower the default nr_inodes limit on machines
with significant highmem.
Be conservative, but more generous than in the original patch to Keith: limit
to number of lowmem pages, which works out around 200,000 on i386. Easily
overridden by giving the nr_inodes= mount option: those who want to sail
closer to the rocks should be allowed to do so.
Notice how tmpfs dentries cannot be reclaimed in the way that disk-based
dentries can: so even hard links need to be costed. They are cheaper than
inodes, but easier all round to charge the same. This way, the limit for hard
links is equally visible through "df -i": but expect occasional bugreports
that tmpfs links are being treated like this.
Would have been simpler just to move the free_inodes accounting from
shmem_delete_inode to shmem_unlink; but that would lose the charge on unlinked
but open files.

[PATCH] ppc64: improved VSID allocation algorithm
This patch has been tested both on SLB and segment table machines. This
new approach is far from the final word in VSID/context allocation, but
it's a noticeable improvement on the old method.
Replace the VSID allocation algorithm. The new algorithm first generates a
36-bit "proto-VSID" (with 0xfffffffff reserved). For kernel addresses this
is equal to the ESID (address >> 28), for user addresses it is:
(context << 15) | (esid & 0x7fff)
These are distinguishable from kernel proto-VSIDs because the top bit is
clear. Proto-VSIDs with the top two bits equal to 0b10 are reserved for
now.
The proto-VSIDs are then scrambled into real VSIDs with the multiplicative
hash:
VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
This scramble is 1:1, because VSID_MULTIPLIER and VSID_MODULUS are co-prime
since VSID_MULTIPLIER is prime (the largest 28-bit prime, in fact).
This scheme has a number of advantages over the old one:
- We now have VSIDs for every kernel address (i.e. everything above
0xC000000000000000), except the very top segment. That simplifies a
number of things.
- We allow for 15 significant bits of ESID for user addresses with 20
bits of context. i.e. 8T (43 bits) of address space for up to 1M
contexts, significantly more than the old method (although we will need
changes in the hash path and context allocation to take advantage of
this).
- Because we use a real multiplicative hash function, we have better and
more robust hash scattering with this VSID algorithm (at least based on
some initial results).
Because the MODULUS is 2^n-1 we can use a trick to compute it efficiently
without a divide or extra multiply. This makes the new algorithm barely
slower than the old one.

[PATCH] ppc64: enable POWER5 low power mode in idle loop
Now that we understand (and have fixed) the problem with using low power mode
in the idle loop, lets enable it. It should save a fair amount of power.
(The problem was that our exceptions were inheriting the low power mode and so
were executing at a fraction of the normal cpu issue rate. We fixed it by
always bumping our priority to medium at the start of every exception).

[PATCH] ppc64: restore smt-enabled=off kernel command line option
Restore the smt-enabled=off kernel command line functionality:
- Remove the SMT_DYNAMIC state now that smt_snooze_delay allows for the
same thing.
- Remove the early prom.c parsing for the option, put it into an
early_param instead.
- In setup_cpu_maps honour the smt-enabled setting
Note to Nathan: In order to allow cpu hotplug add of secondary threads after
booting with smt-enabled=off, I had to initialise cpu_present_map to
cpu_online_map in smp_cpus_done. Im not sure how you want to handle this but
it seems our present map currently does not allow cpus to be added into the
partition that werent there at boot (but were in the possible map).

[PATCH] ppc64: remove EEH command line device matching code
We have had reports of people attempting to disable EEH on POWER5 boxes. This

reads/writes. Remove the IBM location matching code that was being used to
disable devices as well as the global option.
We already have the ability to ignore EEH erros via the panic_on_oops sysctl
option, advanced users should make use of that instead.

[PATCH] ppc64: clean up kernel command line code
Clean up some of our command line code:
- We were copying the command line out of the device tree twice, but the
first time we forgot to add CONFIG_CMDLINE. Fix this and remove the
second copy.
- The command line birec code ran after we had done some command line
parsing in prom.c. This had the opportunity to really confuse the
user, with some options being parsed out of the device tree and the
other out of birecs. Luckily we could find no user of the command
line birecs, so remove them.
- remove duplicate printing of kernel command line;
- clean up iseries inits and create an iSeries_parse_cmdline.

[NET] generalise per protocol slab cache handling
With this patch we get two new slabcaches, for sctp socks, that previously
were being allocated on the default, that was tcp[6]_sock, i.e. wasting 288
bytes per sock in the IPv4 case and 256 bytes for the IPv6 version, this is in
preparation for DCCP (or any other new protocol :) ).
With this in place another nice side effect that is easier to achieve is to
get rid of struct sock sk->sk_slab, and instead use sk->sk_prot->slab, saving
sizeof(void *) on every struct sock instance, but this unfortunatly has to
wait for the conversion of all protocols that use per socket slabcaches to
use sk->sk_prot, AF_UNIX is the only one AFAIK, so I'll try to convert it to
use sk->sk_prot and then get rid of sk->sk_slab.
As for the protocols that don't use per socket slabcaches its just a matter
of defaulting to sk_cachep at sk_free time if sk->sk_prot is NULL.

anyone be relying on the current behaviour.

reason it seems to still work when you don't have spinlock debugging
enabled.
Please apply.
Thanks to Arjan's spinlock debug kernel for finding it.

[IA64] Makefile: fix for the PTRACE_SYSCALL corruption bug
Thanks to David for his help in tracking it down.
compile the kernel with sibling call optimization
turned off. There is a problem with all functions
using the optimization and the asmlinkage attribute.
The compiler should not perform the optimization on
these functions because it cannot preserve the syscall
parameters in the callee. This caused SIGSEGV on programs
traced with PTRACE_SYSCALL, for instance.

[NET] NEIGHBOUR: improve neighbour state machine.
This centralizes neighbour state transition by timer into
neigh_timer_handler(), and kill neigh_sync().
This improves timing accuracy of state transition.
neigh_timer_handler() for each entry is now reponsible
for state transition of the entry, and
neigh_periodic_timer() is just for garbage collection.

Update IsRouter (NTF_ROUTER) flag approrpriately.
Specifically,

- we should set it when we have received RA.
- we should set it when we have received Redirect
whose target is off-link.
