Somewhere in the rewrite of the work queues my cleanup of SAK handling
got broken. Maybe I didn't retest it properly or possibly the API
was changing so fast I missed something. Regardless currently
triggering a SAK now generates an ugly BUG_ON and kills the kernel.
Thanks to Alexey Dobriyan <adobriyan@openvz.org> for spotting this.
This modifies the use of SAK_work to initialize it when the data
structure it resides in is initialized, and to simply call
schedule_work when we need to generate a SAK. I update both
data structures that have a SAK_work member for consistency.
All of the old PREPARE_WORK calls that are now gone.
If we call schedule_work again before it has processed it
has generated the first SAK it will simply ignore the duplicate
schedule_work request.

When CONFIG_PREEMPT is not set, it also moves one branch instruction from
ret_from_irq() to ret_from_exception(). Therefore we favour the return
from irq case which should be more common than the other one.

When I post a patch (commit f431baa55abf8adeed0c718b51deacbc151f58f1),
I just tried to not change behavior of existing codes, but it seems
dec/int-handler.S had been broken since its previous commit
937a801576f954bd030d7c4a5a94571710d87c0b.
The caller of plat_irq_dispatch do setup/restore TI_REGS($28), so
dec's plat_irq_dispatch should not do it, and there is no need to
adjust RA.

Now that finally all supported versions of binutils have functioning
support for .subsection use .subsection to tweak the branch prediction
I did not modify the R10000 errata variants because it seems unclear if
this will invalidate the workaround which actually relies on the cheesy
prediction of branch likely to cause a misspredict if the sc was
successful.

This reverts commit eb3dfb0cb1f4a44e2d0553f89514ce9f2a9fcaf1.
It causes some strange Gnome problem with dbus-daemon getting stuck, so
we'll revert it until that problem is understood.
Reported by both walt and Greg KH, who both independently git-bisected
the problem to this commit.
Andreas is looking at it.

This reverts some bogosity from the dynamic command-line
changes made on sparc32 and sparc64.
Drivers such as drivers/sbus/char/openprom.c reference
saved_command_line, and can be modular.
The boot_command_line is __initdata, yet the dynamic command-line
changes add modular exports of that symbol, obviously wrong.

- Use timer macros to set function and data members and to modify
expiration time.
- Use DEFINE_TIMER for single (platform dependent) watchdog timers and
do not init them at run-time in these cases.
- del_timer_sync is common in most cases -- we want to wait for timer
function if it's still running.

Regarding RFC3775, MH payload proto field should be IPPROTO_NONE. Otherwise
it must be discarded (and the receiver should send ICMP error).

NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables
preemption as well, making it legal to use __get_cpu_var without
disabling preemption manually. The assumption is not correct anymore
with preemptable RCU, additionally we need to protect against softirqs
when not holding nf_conntrack_lock.
Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs,
and use where necessary.
