[PATCH] __kill_pg_info() return value fix
Fix a bug which was spotted by Alex Lyashkov <shadow@psoft.net>

group_send_sig_info() returns an error.

[PATCH] move consistent_dma_mask to the generic device
From: James Bottomley <James.Bottomley@SteelEye.com>
pci_dev.consistent_dma_mask was introduced to get around problems in the
IA64 Altix machine.
Now, we have a use for it in x86: the aacraid needs coherent memory in a
31 bit address range (2GB). Unfortunately, x86 is converted to the dma
model, so it can't see the pci_dev by the time coherent memory is
allocated.
The solution to all of this is to move pci_dev.consistent_dma_mask to
dev.coherent_dma_mask and make x86 use it in the dma_alloc_coherent()
calls.
This should allow me to make the aacraid set the coherent mask instead
of using it's current dma_mask juggling.

[PATCH] module unload deadlock fix
From: Rusty Russell <rusty@rustcorp.com.au>
From: Andrea Arcangeli <andrea@suse.de>
We should drop module sem before calling mod->exit, for practical reasons:
too many module exit functions oops or hang, resulting in a permenantly held

[PATCH] DMA: Fill gaping hole in DMA API interfaces.
From: "David S. Miller" <davem@redhat.com>
Currently, for an existing DMA mapping, there is a way to transfer buffer
ownership back to the cpu, yet there is no way to give it back to the device
again explicitly. The latter really is needed on platforms where the PCI
subsystem does not snoop the cpu caches, MIPS is one example.
Many drivers were expecting the existing DMA sync interface to handle both
directions, which was wrong.
Now, with this change, we have explicit interfaces for DMA syncing to/from
the device and the cpu.

[PATCH] Work around an AMD768MPX erratum
From: Andi Kleen <ak@suse.de>
This patch has been in the SuSE 2.4 kernel forever, but for some reason
never made it mainline.
It works around the infamous "only works stable when a mouse is plugged in"
problem some AMD 768MPX Dual Athlon chipsets have. The problem happens
because the chipset can hang when PCI prefetch strides from a RAM page into
the VGA text buffer. When a PS2 mouse is plugged in the BIOS reserves a
page before the VGA text buffer, which stops the prefetch early.
This patch always reserves this page when the chipset could be AMD768MPX.
This can be only done early in bootmem setup. Because it's difficult to
scan the PCI bus that early it just always reserves this page when the CPU
is an Athlon. Normally it should not make a difference because the BIOS
will have reserved that page anyways when a PS/2 mouse is plugged in.

[PATCH] use wait_task_inactive() in kthread_bind()
From: Rusty Russell <rusty@rustcorp.com.au>
Make it clear that the reason we do wait_task_inactive is because
kthread_bind frobs with k->thread_info->cpu, which is only legal because
the task is definitely not running.
We can't use the normal migration thread code here, because it doesn't let
us bind to cpus which are offline yet, and also because we use this to
start the migration threads themselves.

For all the other system calls that are currently used from inside the

From: Anton Blanchard <anton@samba.org>
Distribute boot time memory allocations across all nodes, from Manfred

Spreading boot time allocations around also helps us to avoid node 0

From: <martin@meltin.net>
Forward-port from 2.4:
The following patch pulls an NFS server IP address off root_server_path
(handed out via the DHCP root-path option), if it is present. For example,
you can do this sort of thing in dhcpd.conf:
root-path = 192.168.1.33:/tftpboot/yip.zImage
This lets you mount your root filesystem off a different machine than you
booted from, without needing to use kernel command-line parameters.
The patch appears to be backwards compatible.
RFC2132 says this about the root-path option:
This option specifies the path-name that contains the client's root
disk. The path is formatted as a character string consisting of
characters from the NVT ASCII character set.
This is sufficiently vague to allow the path-name to include an IP-address.
Also, I found some documentation for FreeBSD saying it does this too, so it
must be right, because those FreeBSD guys are really smart... :-)
The only downside of the patch is that the summary that ipconfig prints can
be a little odd when the kernel command line overrides whatever ipconfig gets
from (say) DHCP. The address from the kernel command line seems to get
stripped off early, so ipconfig reports it, but it doesn't report the kernel
command line NFS path, since that's handled a bit later... This small
cosmetic problem looks difficult to "fix" without rewriting quite a bit of
stuff...

WATCHDOG] v2.6.4 wdt977-v0.03-patch
Version 0.03 of wdt977.c - Changes that were made are:
* Extract the stop code in a seperate function (wdt977_stop)
* Extract the start code in a seperate function (wdt977_start)
* Rename kick_wdog to wdt977_keepalive for consistency
* Extract the watchdog's status code to a seperate function (wdt977_get_status)
* Change the way we deal with the watchdog timeout:
Up till now we used timeoutM (in minutes) as the correct value and then
calculated timeout as being timeoutM*60 or *timeoutM*120 (depending on
wether or not we have the netwinder hardware bug).
From now on timeout is the correct value and we calculate timeoutM out
of it. Because of this we start with checking wether or not we have a
correct timeout value (if not we reset it to the default value) and we
automatically calculate timeoutM. Each time we change timeout with a
correct timeout value, we recalculate timeoutM.
* Extended ioctl code with WDIOC_SETOPTIONS and updated the watchdog_info structure
* Added notifier support
Code has been tested by Woody

[PATCH] Fix removable USB drive oops
The actual problem reported was because there wasn't a corresponding
check on transport_classdev.class in the unregister.
However, on closer inspection I also turned up a nasty thinko in the
reference counting. For reasons best known to the class code authors,
class devices have to obtain their own references to the devices they're
attached to which they release again in their .release routines, so you
have to remember to do a get_device() in the correct place after the
class_device_add(). I put comments in the code so that, hopefully, we
can avoid the problem in future.

[PATCH] Add Domain Validation to the SPI transport class
Domain Validation is a fairly essential element to the SCSI Parallel
Interface (although if you look very few drivers actually do it). The
premise is that the Parallel Bus, being a transmission line, might not
be correctly tuned to the transfers you want do perform. DV probes the
parameters of the transport until it finds a setting that works (for the
interested, see http://www.t10.org/ftp/t10/drafts/sdv/sdv-r08b.pdf)
The current code employs rather simplistic DV heuristics, although those
can be improved over time. The change in scsi_scan.c is so that DV may
be done easily from the slave_configure routine, which is the most
natural place to begin.

[ACPI] ACPICA 20040311 from Bob Moore
Fixed a problem where errors occurring during the parse phase of control
method execution did not abort cleanly. For example, objects created
and installed in the namespace were not deleted. This caused all
subsequent invocations of the method to return the AE_ALREADY_EXISTS
exception.
Implemented a mechanism to force a control method to "Serialized"
execution if the method attempts to create namespace objects.
(The root of the AE_ALREADY_EXISTS problem.)
Implemented support for the predefined _OSI "internal" control method.
Initial supported strings are "Linux", "Windows 2000", "Windows 2001",
and "Windows 2001.1", and can be easily upgraded for new strings as
necessary. This feature allows Linux to execute
the fully tested, "Windows" code path through the ASL code
Global Lock Support: Now allows multiple acquires and releases with any
internal thread. Removed concept of "owning thread" for this special
mutex.
Fixed two functions that were inappropriately declaring large objects on
the CPU stack: ps_parse_loop() and ns_evaluate_relative().
Reduces the stack usage during method execution considerably.
Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the
S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.
Fixed a problem where acpi_ev_gpe_detect() would fault
if there were no GPEs defined on the machine.
Implemented two runtime options: One to force all control method
execution to "Serialized" to mimic Windows behavior, another to disable
_OSI support if it causes problems on a given machine.

[PATCH] update the 53c700 use of transport attributes
This patch just brings it up to date with the previous transport

[PATCH] add device quiescing to the SCSI API
This patch adds the ability to quiesce a SCSI device. The idea is that
user issued commands (including filesystem ones) would get blocked,
while mid-layer and device issued ones would be allowed to proceed.
This is for things like Domain Validation which like to operate on an
otherwise quiet device.
There is one big change: to get all of this to happen correctly,
scsi_do_req() has to queue on the *head* of the request queue, not the
tail as it was doing previously. The reason is that deferred requests
block the queue, so anything needing executing after a deferred request
has to go in front of it. I don't think there are any untoward
consequences of this.

From: Nick Piggin <piggin@cyberone.com.au>
Use a "refill_counter" for inactive list scanning, similar to the one used

No observed benefits, but I imagine it would lower the acquisition
frequency of the lru locks in some cases, and make codepaths more efficient
in general due to cache niceness.

[PATCH] kswapd: fix lumpy page reclaim
As kswapd is now scanning zones in the highmem->normal->dma direction it can
get into competition with the page allocator: kswapd keep on trying to free
pages from highmem, then kswapd moves onto lowmem. By the time kswapd has
done proportional scanning in lowmem, someone has come in and allocated a few
pages from highmem. So kswapd goes back and frees some highmem, then some
lowmem again. But nobody has allocated any lowmem yet. So we keep on and on
scanning lowmem in response to highmem page allocations.
With a simple `dd' on a 1G box we get:

[PATCH] kswapd: avoid unnecessary reclaiming from higher zones
Currently kswapd walks across all zones in dma->normal->highmem order,
performing proportional scanning until all zones are OK. This means that
pressure against ZONE_NORMAL causes unnecessary reclaim of ZONE_HIGHMEM.
To fix that up we change kswapd so that it walks the zones in the
high->normal->dma direction, skipping zones which are OK. Once it encounters
a zone which needs some reclaim kswapd will perform proportional scanning
against that zone as well as all the succeeding lower zones.
We scan the lower zones even if they have sufficient free pages. This is
because
a) the lower zone may be above pages_high, but because of the incremental
min, the lower zone may still not be eligible for allocations. That's bad
because cache in that lower zone will then not be scanned at the correct
rate.
b) pages in this lower zone are usable for allocations against the higher
zone. So we do want to san all the relevant zones at an equal rate.

`priority' numbers, we don't want to thrlttle yet.
- In balance_pgdat(), we may end up not scanning any pages because all
zones happened to be above pages_high. Avoid throttling in this case too.

[PATCH] Balance inter-zone scan rates
When page reclaim is working out how many pages to san in a zone (max-scan)
it presently rounds that number up if it looks too small - for work batching.
Problem is, this can result in excessive scanning against small zones which
have few inactive pages. So remove it.
Not that it is possible for max_scan to be zero. That's OK - it'll become
non-zero as the priority increases.

[PATCH] vmscan: drive everything via nr_to_scan
Page reclaim is currently a bit schitzo: sometimes we say "go and scan this
many pages and tell me how many pages were freed" and at other times we say
"go and scan this many pages, but stop if you freed this many".
It makes the logic harder to control and to understand. This patch coverts
everything into the "go and scan this many pages and tell me how many pages
were freed" model.
It doesn't seem to affect performance much either way.

[PATCH] vmscan: zone balancing fix
We currently have a problem with the balancing of reclaim between zones: much
more reclaim happens against highmem than against lowmem.
This patch partially fixes this by changing the direct reclaim path so it
does not bale out of the zone walk after having reclaimed sufficient pages
from highmem: go on to reclaim from lowmem regardless of how many pages we
reclaimed from lowmem.

[PATCH] vm: scan slab in response to highmem scanning
The patch which went in six months or so back which said "only reclaim slab
if we're scanning lowmem pagecache" was wrong. I must have been asleep at
the time.
We do need to scan slab in response to highmem page reclaim as well. Because
all the math is based around the total amount of memory in the machine, and
we know that if we're performing highmem page reclaim then the lower zones
have no free memory.

[PATCH] kswapd throttling fixes
The logic in balance_pgdat() is all bollixed up.
- the incoming arg `nr_pages' should be used to determine if we're being
asked to free a specific number of pages, not `to_free'.
- local variable `to_free' is not appropriate for the determination of
whether we failed to bring all zones to appropriate free pages levels.
Fix this by correctly calculating `all_zones_ok' and then use
all_zones_ok to determine whether we need to throttle kswapd.
So the logic now is:
for (increasing priority) {
all_zones_ok = 1;
for (all zones) {
to_reclaim = number of pages to try to reclaim
from this zone;
max_scan = number of pages to scan in this pass
(gets larger as `priority' decreases)
/*
* set `reclaimed' to the number of pages which were
* actually freed up
*/
reclaimed = scan(max_scan pages);
reclaimed += shrink_slab();
to_free -= reclaimed; /* for the `nr_pages>0' case */
/*
* If this scan failed to reclaim `to_reclaim' or more
* pages, we're getting into trouble. Need to scan
* some more, and throttle kswapd. Note that this
* zone may now have sufficient free pages due to
* freeing activity by some other process. That's
* OK - we'll pick that info up on the next pass
* through the loop.
*/
if (reclaimed < to_reclaim)
all_zones_ok = 0;
}
if (to_free > 0)
continue; /* swsusp: need to do more work */
if (all_zones_ok)
break; /* kswapd is done */
/*
* OK, kswapd is getting into trouble. Take a nap, then take
* another pass across the zones.

Kronos <kronos@kronoz.cjb.net>
Various fixes and enhancements to the monitor hardware detection code. The

Old EDID parsing code was very verbose, half of the patch address this (ie.

stuff: we really need a way to know the origin of a video mode. In this way
we can select video mode that comes from EDID instead of VESA or GTF.
Drivers other than radeonfb won't be affected because they cannot (yet) get
EDID from the monitor and don't use EDID related code.

[PATCH] EDD: Get Legacy Parameters
From: Matt Domsch <Matt_Domsch@dell.com>
Patch below from Patrick J. LoPresti and myself. Patrick describes:
Why this patch? The problem is that the legacy BIOS interface
(INT13/AH=3D08) for querying the disk geometry returns different values
than the extended INT13 interface which the EDD code currently uses. This
is because the legacy interface only provides a 10-bit cylinder field, so
modern BIOSes "lie" about the head/sector counts in order to make more of
the disk visible within the first 1024 cylinders.
Many non-Linux applications, including the stock Windows boot loader, DOS
fdisk, etc., rely upon the legacy interface and geometry. So it is useful
to be able to obtain the legacy values from a running Linux kernel.
What this patch does is to add new entries under
/sys/firmware/edd/int13_devXX named "legacy_cylinders", "legacy_heads", and
"legacy_sectors". These provide the geometry given by the legacy
INT13/AH=3D08 BIOS interface, just like the current "default_cylinders"
etc. provide the the geometry given by the INT13/AH=3D48 interface.
Without this patch, I cannot use Linux to partition a drive and install
Windows, which happens to be my application.
- Pat
http://unattended.sourceforge.net/
In addition, this adds two buggy BIOS workarounds in the EDD int13
calls as suggested by Ralf Brown's interrupt list.
I'm also interested in moving this code out of arch/i386/kernel/edd.c and
include/asm-i386/edd.h, as I believe it is applicable on x86-64 as well.
However, there's no good place under drivers/ to put edd.c when it's not
tied to a bus, but to several CPU architectures and their firmwares...
Maybe a new directory drivers/firmware?

[PATCH] Fix reading the last block on a bdev
From: Chris Mason <mason@suse.com>
This patch fixes a problem we're hitting on ia64 with page sizes > 4k.
When the page size is greater than the block size, and parts of the page

blkdev_get_block returns -EIO for blocks past i_size.
The attached patch changes blkdev_get_block to return holes when reading
past the end of the device, which allows us to read that last valid 4k
block and then fill the rest of the page with zeros. Writes will still

[PATCH] loop setup race fix
From: Chris Mason <mason@suse.com>
There's a race in loopback setup, it's easiest to trigger with one or more
procs doing loopback mounts at the same time. The problem is that
fs/block_dev.c:do_open() only calls bdev_set_size on the first open.
Picture two procs:
proc1: mount -o loop file1 mnt1
proc2: mount -o loop file2 mnt2
proc1 proc2
open /dev/loop0 # bd_openers now 1
do_open
bd_set_size(bdev, 0) # loop unbound, so bdev size is 0
open /dev/loop0 # bd_openers now 2
loop_set_fd # disk capacity now correct, but
# bdev not updated
mount /dev/loop0 /mnt
do_open
Because bd_openers != 0 for the last do_open, bd_set_size is not called
again and a size of 0 is used. This eventually leads to an oops when the
loop device is unmounted, because fsync_bdev calls block_write_full_page
who decides every page on the block device is outside i_size and unmaps
them.
When ext2 or reiserfs try to sync a metadata buffer, we get an oops on
because the buffers are no longer mapped.
The patch below changes loop_set_fd and loop_clr_fd to also manipulate the
size of the block device, which fixes things for me.

[PATCH] LOOP_CHANGE_FD ioctl
From: Arjan van de Ven <arjanv@redhat.com>
The patch below (written by Al Viro) solves a nasty chicken-and-egg issue
for operating system installers (well at least anaconda but the problem
domain is not exclusive to that)
The basic problem is this:
- The small first stage installer locates the image file of the second
stage installer (which has X and all the graphical stuff); this image can
be on the same CD, but it can come via NFS, http or ftp or ... as well.
- The first stage installer loop-back mounts this image and gives control
to the second stage installer by calling some binary there.
- The graphical installer then asks the user all those questions and
starts installing packages. Again the packages can come from the CD but
also from NFS or http or ...
Now in case of a CD install, once all requested packages from the first CD
are installed, the installer wants to unmount and eject the CD and prompt
the user to put CD 2 in....... EXCEPT that the unmount can't work since
the installer is actually running from a loopback mount of this cd.
The solution is a "LOOP_CHANGE_FD" ioctl, where basically the installer
copies the image to the harddisk (which can only be done late since only
late the target harddisk is mkfs'd) and then magically switches the backing
store FD from underneath the loop device to the one on the target harddisk
(and thus unbusying the CD mount).
This is obviously only allowed if the size of the new image is identical
and if the loop image is read-only in the first place. It's the

[PATCH] kbuild: Cause `make clean' to remove more files
From: Sam Ravnborg <sam@ravnborg.org>
Make the difference between 'make clean' and 'make distclean/mrproper' more
explicit.
make clean now removes all generated files except .config* and .version.
The result is much easier to understand now.
make clean deletes all generated files (except .config* and .version).
make mrproper deletes configuration and all temporary files left by patch,
editors and the like.
Example output:
> make mrproper
CLEAN init
CLEAN usr
CLEAN scripts/kconfig
CLEAN scripts
CLEAN .tmp_versions include/config
CLEAN include/asm-i386/asm_offsets.h include/linux/autoconf.h include/linux/version.h include/asm .tmp_versions
CLEAN .version .config
Form the list of files/directories deleted during make clean, removed all
references that is no longer relevant for the current kernel.

[PATCH] NUMA-aware zonelist builder
From: <j-nomura@ce.jp.nec.com>

[PATCH] i386 very early memory detection cleanup patch
From: "H. Peter Anvin" <hpa@zytor.com>
This patch cleans up the very early memory setup on the i386 platform. In
particular, it removes the hard-coded 8 MB limit completely by dynamically
creating the early-boot pagetables rather than having them hard coded.
While I was at it, I changed head.S so that it always sets up a local GDT;
this means among other things that SMP and VISWS are no longer special
cases, and is conceptually cleaner to boot. The VISWS people have
confirmed it works on VISWS.
It also uses a separate entrypoint for non-boot processors since this is
completely kernel-internal anyway. This eliminates the need to set %bx on
boot. (If you think this is a bad idea I can eliminate this change; it
just seemed cleaner to me to do it this way.)
Additionally, zero bss with rep;stosl rather that rep;stosb.

[PATCH] time interpolator fix
From: john stultz <johnstul@us.ibm.com>
In developing the ia64-cyclone patch, which implements a cyclone based time
interpolator, I found the following bug which could cause time
inconsistencies.
In update_wall_time_one_tick(), which is called each timer interrupt, we
call time_interpolator_update(delta_nsec) where delta_nsec is approximately
NSEC_PER_SEC/HZ. This directly correlates with the changes to xtime which
occurs in update_wall_time_one_tick().
However in update_wall_time(), on a second overflow, we again call
time_interpolator_update(NSEC_PER_SEC). However while the components of
xtime are being changed, the overall value of xtime does not (nsec is
decremented NSEC_PER_SEC and sec is incremented). Thus this call to
time_interpolator_update is incorrect.
This patch removes the incorrect call to time_interpolator_update and was
found to resolve the time inconsistencies I had seen while developing the
ia64-cyclone patch.

[PATCH] adaptive lazy readahead
From: Suparna Bhattacharya <suparna@in.ibm.com>
From: Ram Pai <linuxram@us.ibm.com>
Pipelined readahead behaviour is suitable for sequential reads, but not for
large random reads (typical of database workloads), where lazy readahead
provides a big performance boost.
One option (suggested by Andrew Morton) would be to have the application
pass hints to turn off readahead by setting the readahead window to zero
using posix_fadvise64(POSIX_FADV_RANDOM), and to special-case that in
do_generic_mapping_read to completely bypass the readahead logic and
instead read in all the pages needed directly.
This was the idea I started with. But then I thought, we can do a still
better job ? How about adapting the readahead algorithm to lazy-read or
non-lazy-read based on the past i/o patterns ?
The overall idea is to keep track of average number of contiguous pages
accessed in a file. If the average at any given time is above ra->pages
the pattern is sequential. If not the pattern is random. If pattern is
sequential do non-lazy-readahead( read as soon as the first page in the
active window is touched) else do lazy-readahead.
I have studied the behaviour of this patch using my user-level simulator.
It adapts pretty well.
Note from Suparna: This appears to bring streaming AIO read performance for
large (64KB) random AIO reads back to sane values (since the lazy readahead
backout in the mainline).

[PATCH] readdir() cleanups
From: <viro@parcelfarce.linux.theplanet.co.uk>
cramfs and freevxfs explicitly mark themselves readonly (as other r/o fs

afs marked noatime (ACKed by maintainer)
filesystems that do not do update_atime() in their ->readdir() had been
explicitly marked nodiratime. NOTE: cifs, coda and ncpfs almost certainly
need full noatime as we currently have in nfs and afs.
update_atime() call shifted to callers of ->readdir() and out of
->readdir() instances. Bugs caught:
dcache_readdir() updated atime only if it reached EOF.
bfs_readdir() - ditto.
qnx4_readdir() - ditto.

[PATCH] ppc64: fix initialisation of NUMA arrays
From: Anton Blanchard <anton@samba.org>
We were hitting problems on machines with cpu_possible != cpu_online when

Longer term we should have a cpu_up hook which sets up its NUMA information
but for now we initalise all possible cpus and memory to node 0.

Thanks to some great debugging work by Olaf Hering and Marcus Meissner
it has been noticed that the current ppc64 syscall code is corrupting
4 bytes past errno. Why we even bothered to set errno beats me, its
unusable in the kernel.
Since we had to reinstate the inline syscall code we can go back to
using it for those few syscalls that we call. Especially now with
Randy's syscall prototype cleanup we should be calling them directly
but we can do that sometime later.

to what you can do with bio_map_user() already to a bio. However, this

converts sg_io() to use it, next patch I'll send adapts cdrom layer to
use it for zero copy cdda dma extraction.

ia64: don't unmask iosapic interrupts by default
In ia64 kernel, IOSAPIC's RTEs for PCI interrupts are unmasked at the
boot time before installing device drivers. I think it is very dangerous.
If some PCI devices without device driver generate interrupts, interrupts
are generated repeatedly because these interrupt requests are never
cleared. I think RTEs for PCI interrupts should be unmasked by device
driver. This patch fixes the problem.

[PATCH] x86-64 merge for 2.6.4
The biggest new feature is fixed 32bit vsyscall (SYSCALL+SYSENTER)
support, mostly from Jakub Jelinek. This increases 32bit syscall
performance greatly (latency halved and better). The SYSENTER for Intel
support required some infrastructure changes, but seems to work now too.
The 64bit vsyscall vtime() just references xtime.tv_sec now. This
should make it a lot faster too.
A fix for some Intel IA32e systems. Also a few long standing bugs in
NMI like exception handlers were fixed.
And a lot of other bug fixes.
Full changeLog:
- Clean up 32bit address room limit handling, fix 3gb personality
- Move memcpy_{from,to}io export to ksyms.c file. This seems to work
around a toolchain bug (Andreas Gruenbacher)
- Update defconfig
- ACPI merges from i386 (SBF should work now, acpi=strict)
- Implement mmconfig support based on i386 code (untested)
- Fix i386/x86-64 pci source file sharing
- Implement ptrace access for 32bit vsyscall page

- Remove explicit CPUID in ia32 syscall code
- Fill in most of boot_cpu_data early
- Remove unused PER_LINUX32 setup
- Fix syscall trace in fast 32bit calls (Suresh B. Siddha)
- Tighten first line of the oops again.
- Set up ptrace registers correctly for debug,ss,double fault exceptions
- Fix 64bit bug in sys_time64

- Use an exception stack for machine checks
- Handle TIF_SINGLESTEP properly in kernel exit
- Add exception stack for debug handler
- Disable X86_HT for Opteron optimized builds because it pulls in ACPI_BOOT
