* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT
This will make hardirq.h inclusion cheaper for every PREEMPT=n config
(which includes allmodconfig/allyesconfig, BTW)

Pull the initial preempt_count value into a single
definition site.
Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.
The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

Commit 1faa16d22877f4839bd433547d770c676d1d964c accidentally broke
the bdi congestion wait queue logic, causing us to wait on congestion
for WRITE (== 1) when we really wanted BLK_RW_ASYNC (== 0) instead.

Alex found that specjbb2005 still can not run with hugepages on an
x86-64 machine. This only happens when numa is not compiled in.
The root cause: node_set_state will not set it back for us in that case,
so don't clear that when numa is not select in config
[ v2: use node_clear_state instead ]

Patch 08687aec71bc9134fe336e561f6did877bacf74fc0a (x86: unify
power/cpu_(32|64).c) renamed cpu_32.c to cpu.c, but did not update

Current implementation of spin_event_timeout can be interrupted by an
IRQ or context switch after testing the condition, but before checking
the timeout. This can cause the loop to report a timeout when the
condition actually became true in the middle.
This patch adds one final check of the condition upon exit of the loop
if the last test of the condition was still false.

Our udelay implementation enables interrupts to receive a special timer
interrupt regardless of the context it is called from.
This might lead to false positive lockdep reports. Since lockdep isn't
aware of the fact that only a single interrupt source is enabled it
warns about possible deadlocks that in reality won't happen, like
the one below.
To fix this disable lockdep before enabling interrupts.

below the elevator voltage. Remove the checks that prevent
this configuration from being supported and increase the
transition voltage to prevent errors during the transition.
