[POWERPC] Clear RI bit in MSR before restoring r13 when returning to userspace
Some instruction tracing tools use the RI (recoverable interrupt) bit
in the MSR to indicate when it's safe to single-step. Currently we
clear RI after restoring r13 when returning to userspace. However,
if we single-step past the point where r13 is restored, we'll corrupt
r13 in the exception entry code and not restore it. This moves the
clearing of RI to just before r13 is restored so this doesn't happen.

[POWERPC] Fix performance monitor exception
To the issue: some point during 2.6.20 development, Paul Mackerras
introduced the "lazy IRQ disabling" patch (very cool work, BTW).
In that patch, the performance monitor unit exception was marked as
"maskable", in the sense that if interrupts were soft-disabled, that
exception could be ignored. This broke my PowerPC profiling code.
The symptom that I see is that a varying number of interrupts
(from 0 to $n$, typically closer to 0) get delivered, when, in
reality, it should always be very close to $n$.
The issue stems from the way masking is being done. Masking in
this fashion seems to work well with the decrementer and external
interrupts, because they are raised again until "really" handled.
For the PMU, however, this does not apply (at least on my Xserver
machine with a 970FX processor). If the PMU exception is not handled,
it will _not_ be re-raised (at least on my machine). The documentation
states that the PMXE bit in MMCR0 is set to 0 when the PMU exception
is raised. However, software must re-set the bit to re-enable PMU
exceptions. If the exception is ignored (as currently) not only is
that interrupt lost, but because software does not re-set PMXE, the
PMU registers are "frozen" forever.
[This patch means that performance monitor exceptions are taken and
handled even if irqs are off, as long as some other interrupt hasn't
come along and caused interrupts to be hard-disabled. In this sense
the PMU exception becomes like an NMI. The oprofile code for most
powerpc processors does nothing that is unsafe in an NMI context, but
the Cell oprofile code does a spin_lock_irqsave. However, that turns
out to be OK because Cell doesn't actually use the performance
monitor exception; performance monitor interrupts come in as a
regular interrupt on Cell, so will be disabled when irqs are off.

[POWERPC] pSeries: EEH improperly enabled for some Power4 systems
It appears that EEH is improperly enabled for some Power4 systems.
On these systems, the ibm,set-eeh-option returns a value of success
even when EEH is not supported on the given node. Thus, an explicit
check for support is required.
During boot, on power4, without this patch, one sees messages
similar to:
EEH: event on unsupported device, rc=0 dn=/pci@
400000000110/IBM,sp@1
EEH: event on unsupported device, rc=0 dn=/pci@
400000000110/pci@2
EEH: event on unsupported device, rc=0 dn=/pci@
400000000110/pci@2,2
etc.
The patch makes these go away.
Without this patch, EEH recovery does seem to work correctly for
at least some devices (I tested ethernet e1000), but fails to
recover others (the Emulex LightPulse LPFC, most notably).
Off the top of my head, I don't remember why some devices are
affected, but not others.
The PAPR indicates that the correct way to test for EEH is as
done in this patch; its not clear to me if this was in the PAPR
all along, or recently added; if it was there all along, its not
clear to me why this hadn't been fixed long ago. I suspect only
certain firmware levels are affected.

[PATCH] kexec: Avoid migration of already disabled irqs (ia64)
This patch fixes up ia64 kexec support for HP rx2620 hardware. It does
this by skipping migration of already disabled irqs. This is most likely a
problem on other ia64 platforms as well, but I've only been able to
reproduce it on one machine so far.
The full story is that handle_bad_irq() gets invoked before starting the
new kernel without this patch. This seems to happen when fixup_irqs()
calls generic_handle_irq() on already migrated (and disabled) irqs. So by
avoiding migration of disabled irqs we stay away of handle_bad_irq().
The code has been tested on three different ia64 machines, all with good
results. It is possible to trigger the same bug by offlining a processor
using echo 0 > /sys/devices/system/cpu/cpuX/online.

flush_workqueue() is not allowed to be called in the softirq context.
However, aio_complete() called from I/O interrupt can potentially call
put_ioctx with last ref count on ioctx and triggers bug. It is simply
incorrect to perform ioctx freeing from aio_complete.
The bug is trigger-able from a race between io_destroy() and aio_complete().
A possible scenario:
cpu0 cpu1
io_destroy aio_complete
wait_for_all_aios { __aio_put_req
... ctx->reqs_active--;
if (!ctx->reqs_active)
return;
}
...
put_ioctx(ioctx)
put_ioctx(ctx);
__put_ioctx
bam! Bug trigger!
The real problem is that the condition check of ctx->reqs_active in
wait_for_all_aios() is incorrect that access to reqs_active is not
being properly protected by spin lock.
This patch adds that protective spin lock, and at the same time removes
all duplicate ref counting for each kiocb as reqs_active is already used
as a ref count for each active ioctx. This also ensures that buggy call
to flush_workqueue() in softirq context is eliminated.

[SCSI] sd: udev accessing an uninitialized scsi_disk field results in a crash
sd_probe() calls class_device_add() even before initializing the
sdkp->device variable. class_device_add() eventually results in the user mode
udev program to be called. udev program can read the the allow_restart
attribute of the newly created scsi device. This is resulting in a crash as
the show function for allow_restart (i.e sd_show_allow_restart) returns the
attribute value by reading the sdkp->device->allow_restart variable. As the
sdkp->device is not initialized before calling the user mode hotplug helper,
this results in a crash.
The patch below solves it by calling class_device_add() only after the
necessary fields in the scsi_disk structure are initialized properly.

It waits in 10uS chunks while 1uS chunks were used in the workaround.
Could indeed do that once I know the fix is right. While I'm at it the
ata_busy_wait kerneldoc is borked so here's a fix

ahci/pata_jmicron: fix JMicron quirk
For all JMicrons except for 361 and 368, AHCI mode enable bits in the
Control(1) should be set. This used to be done in both ahci and
pata_jmicron but while moving programming to PCI quirk, it was removed
from ahci part while still left in pata_jmicron.
The implemented JMicron PCI quirk was incorrect in that it didn't
program AHCI mode enable bits. If pata_jmicron is loaded first and
programs those bits, the ahci ports work; otherwise, ahci device
detection fails miserably.
This patch makes JMicron PCI quirk clear SATA IDE mode bits and set
AHCI mode bits and remove the respective part from pata_jmicron.
Tested on JMB361, 363 and 368.

Revert "[PATCH] fix typo in geode_configre()@cyrix.c"
This reverts commit
e4f0ae0ea63caceff37a13f281a72652b7ea71ba.
It's not wrong, but it's not right either, and everybody seems to agree
that the right fix is probably to do the ccr3 write after the ccr4 one
(and that we also should clean it up a bit). And after that we need to
really validate that all the bits that we write to ccr4 actually do
work.
The old 2.6.19 code was insane, and basically didn't change ccr4 at all
(even though it certainly looks like it was the *intent* to do so). So
let's revert the change that may fix things, just because it's not what
was actually ever tested when the code was written, even if it _was_ the
intent.
There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was
started by the patch that now gets reverted, and that discussion may
well contain the proper long-term fix.
