This patch corrects an error when demuxing the DMA irq's
DMA1 was used as a base and this should have been DMA0.
Without this fix we do not process DMA0 irq's and the
system effectively locks up in a loop trying the process
the irq it never can.

Trying to build some code using atomic_clear_mask() on a ARM v6
processor with a recent compiler (tried with gcc version 4.1.1
(CodeSourcery ARM Sourcery G++ 2006q3-26), but
all gcc > 4.1 might be affected) results in the following:
/tmp/ccWKLJV8.s: Assembler messages:
/tmp/ccWKLJV8.s:581: Error: instruction does not accept this addressing
mode -- `ldrex r0,r3'
/tmp/ccWKLJV8.s:583: Error: instruction does not accept this addressing
mode -- `strex r1,r0,r3'
Older gcc (like gcc version 4.0.0 (DENX ELDK 4.1 4.0.0)) have no problem
with this.
The patch below fixes the compile error. I also verified that gcc-4.0.0 generates identical code using both forms.

72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc inverted the sense for
enabling hotplug CPU controls without reference to any other
architecture other than i386, ia64 and PowerPC. This left
everyone else without hotplug CPU control.

I noticed that in xfrm_state_add we look for the larval SA in a few
places without checking for protocol match. So when using both
AH and ESP, whichever one gets added first, deletes the larval SA.
It seems AH always gets added first and ESP is always the larval
SA's protocol since the xfrm->tmpl has it first. Thus causing the
additional km_query()
Adding the check eliminates accidental double SA creation.

VMI is broken under COMPAT_VDSO, as Xen and other non hardware assisted
hypervisors will be. I have been working on a fix for this which works
for older glibcs that panic when the new relocatable VDSO is used.
However, I believe at this time that the fix is going to be too radical
to consider at this stage in the release of 2.6.21. We don't expect
this config option to be turned on by vendors for new distributions, so
at this point we are willing to drop support for it when VMI is compiled
in, and work on a patch for 2.6.22 which more fully addresses the
problem.

times.
Because we do not reserve space for the pci-x and pci-e state in struct
pci dev we need to dynamically allocate it. However because we need
to support restore being called multiple times after a single save
it is never safe to free the buffers we have allocated to hold the
state.
So this patch modifies the save routines to first check to see
if we have already allocated a state buffer before allocating
a new one. Then the restore routines are modified to not free
the state after restoring it. Simple and it fixes some subtle
error path handling bugs, that are hard to test for.

There are two ways pci_save_state and pci_restore_state are used. As
helper functions during suspend/resume, and as helper functions around
a hardware reset event. When used as helper functions around a hardware
reset event there is no reason to believe the calls will be paired, nor
is there a good reason to believe that if we restore the msi state from
before the reset that it will match the current msi state. Since arch
code may change the msi message without going through the driver, drivers
currently do not have enough information to even know when to call
pci_save_state to ensure they will have msi state in sync with the other
kernel irq reception data structures.
It turns out the solution is straight forward, cache the state in the
existing msi data structures (not the magic pci saved things) and
have the msi code update the cached state each time we write to the hardware.
This means we never need to read the hardware to figure out what the hardware
state should be.
By modifying the caching in this manner we get to remove our save_state
routines and only need to provide restore_state routines.
The only fields that were at all tricky to regenerate were the msi and msi-x
control registers and the way we regenerate them currently is a bit dependent
upon assumptions on how we use the allow msi registers to be configured and used
making the code a little bit brittle. If we ever change what cases we allow
or how we configure the msi bits we can address the fragility then.

Commit 484b366932be0b73a22c74a82748ca10a721643e added support for the CIPSO
ranged categories tag. However, it appears that I made a mistake when rebasing
then patch to the latest upstream sources for submission and dropped the part
of the patch that actually parses the tag on incoming packets. This patch
fixes this mistake by adding the required function call to the
cipso_v4_skbuff_getattr() function.
I've run this patch over the weekend and have not noticed any problems.

This reverts commit d2487cb4257dafb686f682285854fe7f02ca29d8.
Russell King points out that it's obviously bogus, and I have to agree.
Not only does "irq" not even exist in that scope, but we obviously need
to free the irq that we actually requested, and that's IRQ_USB.

Fix atomicity of TIF update in flush_thread() for sparc64
Fixes correctly the race by using *_ti_thread_flag.
Race :
parent process executing :
sys_ptrace()
(lock_kernel())
(ptrace_get_task_struct(pid))
arch_ptrace()
ptrace_detach()
ptrace_disable(child);
clear_singlestep(child);
clear_tsk_thread_flag(child, TIF_SINGLESTEP);
(which clears the TIF_SINGLESTEP flag atomically from a different
process)
(put_task_struct(child))
(unlock_kernel())
And at the same time, in the child process :
sys_execve()
do_execve()
search_binary_handler()
load_elf_binary()
flush_old_exec()
flush_thread()
doing a non-atomic thread flag update

Delay the read of the EC status register until
after the event that caused it occurs -- otherwise
it is possible to read and act on stale status that was
associated with the previous event.
Do this with a perpetually incrementing "event_count" to detect
when a new event occurs and it is safe to read status.
There is no workaround for polling mode -- it is inherently
exposed to reading and acting on stale status, since it
doesn't have an interrupt to tell it the event completed.
