Revert "x86-64: Disable local APIC timer use on AMD systems with C1E"
This reverts commit
e66485d747505e9d960b864fc6c37f8b2afafaf0, since
Rafael Wysocki noticed that the change only works for his in -mm, not in
mainline (and that both "noapictimer" _and_ "apicmaintimer" are broken
on his hardware, but that's apparently not a regression, just a symptom
of the same issue that causes the automatic apic timer disable to not
work).
It turns out that it really doesn't work correctly on x86-64, since
x86-64 doesn't use the generic clock events for timers yet.
Thanks to Rafal for testing, and here's the ugly details on x86-64 as
per Thomas:
"I just looked into the code and the logic vs. noapictimer on SMP is
completely broken.
On i386 the noapictimer option not only disables the local APIC
timer, it also registers the CPUs for broadcasting via IPI on SMP
systems.
The x86-64 code uses the broadcast only when the local apic timer is
active, i.e. "noapictimer" is not on the command line. This defeats
the whole purpose of "noapictimer". It should be there to make boxen
work, where the local APIC timer actually has a hardware problem,
e.g. the nx6325.
The current implementation of x86_64 only fixes the ACPI c-states
related problem where the APIC timer stops in C3(2), nothing else.
On nx6325 and other AMD X2 equipped systems which have the C1E
enabled we run into the following:
PIT keeps jiffies (and the system) running, but the local APIC timer
interrupts can get out of sync due to this C1E effect.
I don't think this is a critical problem, but it is wrong
nevertheless.
I think it's safe to revert the C1E patch and postpone the fix to the
clock events conversion."
On further reflection, Thomas noted:
"It's even worse than I thought on the first check:
"noapictimer" on the command line of an SMP box prevents _ONLY_ the
boot CPU apic timer from being used. But the secondary CPU is still
unconditionally setting up the APIC timer and uses the non
calibrated variable calibration_result, which is of course 0, to
setup the APIC timer. Wreckage guaranteed."
so we'll just have to wait for the x86 merge to hopefully fix this up
for x86-64.

x86-64: Disable local APIC timer use on AMD systems with C1E
commit
3556ddfa9284a86a59a9b78fe5894430f6ab4eef titled
[PATCH] x86-64: Disable local APIC timer use on AMD systems with C1E
solves a problem with AMD dual core laptops e.g. HP nx6325 (Turion 64
X2) with C1E enabled:
When both cores go into idle at the same time, then the system switches
into C1E state, which is basically the same as C3. This stops the local
apic timer.
This was debugged right after the dyntick merge on i386 and despite the
patch title it fixes only the 32 bit path.
x86_64 is still missing this fix. It seems that mainline is not really
affected by this issue, as the PIT is running and keeps jiffies
incrementing, but that's just waiting for trouble.
-mm suffers from this problem due to the x86_64 high resolution timer
patches.
This is a quick and dirty port of the i386 code to x86_64.
I spent quite a time with Rafael to debug the -mm / hrt wreckage until
someone pointed us to this. I really had forgotten that we debugged this
half a year ago already.
Sigh, is it just me or is there something yelling arch/x86 into my ear?

sata_sil24: fix IRQ clearing race when PCIX_IRQ_WOC is used
When PCIX_IRQ_WOC is used, sil24 has an inherent race condition
between clearing IRQ pending and reading IRQ status. If IRQ pending
is cleared after reading IRQ status, there's possibility of lost IRQ.
If IRQ pending is cleared before reading IRQ status, spurious IRQs
will occur.
sata_sil24 till now cleared IRQ pending after reading IRQ status thus
losing IRQs on machines where PCIX_IRQ_WOC was used. Reverse the

raid5: fix 2 bugs in ops_complete_biofill
1/ ops_complete_biofill tried to avoid calling handle_stripe since all the
state necessary to return read completions is available. However the
process of determining whether more read requests are pending requires
locking the stripe (to block add_stripe_bio from updating dev->toead).
ops_complete_biofill can run in tasklet context, so rather than upgrading
all the stripe locks from spin_lock to spin_lock_bh this patch just
unconditionally reschedules handle_stripe after completing the read
request.
2/ ops_complete_biofill needlessly qualified processing R5_Wantfill with
dev->toread. The result being that the 'biofill' pending bit is cleared
before handling the pending read-completions on dev->read. R5_Wantfill can
be unconditionally handled because the 'biofill' pending bit prevents new
R5_Wantfill requests from being seen by ops_run_biofill and
ops_complete_biofill.

IB/mlx4: Fix data corruption triggered by wrong headroom marking order
This is an addendum to commit
0e6e7416 ("IB/mlx4: Handle new FW
requirement for send request prefetching"). We also need to handle
prefetch marking properly for S/G segments, or else the HCA may end up
processing S/G segments that are not fully written and end up sending
the wrong data. This can actually cause data corruption in practice,
especially on systems with relatively slow CPUs (where the HCA is more
likely to prefetch while the CPU is in the middle of writing a work
request into memory).
We write S/G segments in reverse order into the WQE, in order to
guarantee that the first dword of all cachelines containing S/G
segments is written last (overwriting the headroom invalidation
pattern). The entire cacheline will thus contain valid data when the
invalidation pattern is overwritten.

clockevents: remove the suspend/resume workaround^Wthinko
In a desparate attempt to fix the suspend/resume problem on Andrews
VAIO I added a workaround which enforced the broadcast of the oneshot
timer on resume. This was actually resolving the problem on the VAIO
but was just a stupid workaround, which was not tackling the root
cause: the assignement of lower idle C-States in the ACPI processor_idle
code. The cpuidle patches, which utilize the dynamic tick feature and
go faster into deeper C-states exposed the problem again. The correct
solution is the previous patch, which prevents lower C-states across
the suspend/resume.
Remove the enforcement code, including the conditional broadcast timer
arming, which helped to pamper over the real problem for quite a time.
The oneshot broadcast flag for the cpu, which runs the resume code can
never be set at the time when this code is executed. It only gets set,
when the CPU is entering a lower idle C-State.

ACPI: disable lower idle C-states across suspend/resume
device_suspend() calls ACPI suspend functions, which seems to have undesired
side effects on lower idle C-states. It took me some time to realize that
especially the VAIO BIOSes (both Andrews jinxed UP and my elfstruck SMP one)
show this effect. I'm quite sure that other bug reports against suspend/resume
about turning the system into a brick have the same root cause.
After fishing in the dark for quite some time, I realized that removing the ACPI
processor module before suspend (this removes the lower C-state functionality)
made the problem disappear. Interestingly enough the propability of having a
bricked box is influenced by various factors (interrupts, size of the ram image,
...). Even adding a bunch of printks in the wrong places made the problem go
away. The previous periodic tick implementation simply pampered over the
problem, which explains why the dyntick / clockevents changes made this more
prominent.
We avoid complex functionality during the boot process and we have to do the
same during suspend/resume. It is a similar scenario and equaly fragile.
Add suspend / resume functions to the ACPI processor code and disable the lower
idle C-states across suspend/resume. Fall back to the default idle
implementation (halt) instead.

wide transfers and if this fails, it turns the wide bit off. The

[PATCH] softmac: Fix inability to associate with WEP networks
Commit
4cf92a3c was submitted as a fix for bug #8686 at bugzilla.kernel.org
(http://bugzilla.kernel.org/show_bug.cgi?id=8686). Unfortunately, the fix led to
a new bug, reported by Yoshifuji Hideaki, that prevented association for WEP
encrypted networks that use ifconfig to control the device. This patch effectively
reverts the earlier commit and does a proper fix for bug #8686.

ACPI: suspend: consolidate handling of Sx states.
Recent changes to sleep initialization in ACPI dropped reporting of supported Sx
states above S3. Fix that and also move S5 init into same file as other Sx.
The only functional change is adding printk() for S4 and S5 cases.

ocfs2: Pack vote message and response structures
The ocfs2_vote_msg and ocfs2_response_msg structs needed to be
packed to ensure similar sizeofs in 32-bit and 64-bit arches. Without this,
we had inadvertantly broken 32/64 bit cross mounts.

ocfs2: Don't double set write parameters
The target page offsets were being incorrectly set a second time in
ocfs2_prepare_page_for_write(), which was causing problems on a 16k page
size kernel. Additionally, ocfs2_write_failure() was incorrectly using those
parameters instead of the parameters for the individual page being cleaned
up.

ocfs2: Fix pos/len passed to ocfs2_write_cluster
This was broken for file systems whose cluster size is greater than page
size. Pos needs to be incremented as we loop through the descriptors, and
len needs to be capped to the size of a single cluster.

ocfs2: Allow smaller allocations during large writes
The ocfs2 write code loops through a page much like the block code, except
that ocfs2 allocation units can be any size, including larger than page
size. Typically it's equal to or larger than page size - most kernels run 4k
pages, the minimum ocfs2 allocation (cluster) size.
Some changes introduced during 2.6.23 changed the way writes to pages are
handled, and inadvertantly broke support for > 4k page size. Instead of just
writing one cluster at a time, we now handle the whole page in one pass.
This means that multiple (small) seperate allocations might happen in the
same pass. The allocation code howver typically optimizes by getting the
maximum which was reserved. This triggered a BUG_ON in the extend code where
it'd ask for a single bit (for one part of a > 4k page) and get back more
than it asked for.
Fix this by providing a variant of the high level allocation function which
allows the caller to specify a maximum. The traditional function remains and
just calls the new one with a maximum determined from the initial
reservation.
