When calling into the EFI firmware, the parameters need to be passed on
the stack. The recent change to use -mregparm=3 breaks x86 EFI support.
This patch is needed to allow the new Intel-based Macs to suspend to ram

The SN Altix platform does not conform to the IOSAPIC IRQ routing model.

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.More detailed information is available in the following mail thread:

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.Signed-off-by: "Ken Chen"

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.Signed-off-by: Nagendra Singh Tomar

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.

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.Suggested-by: Adrian Bunk
