This reverts commit 0ac0c0d0f837c499afd02a802f9cf52d3027fa3b, which
caused cross-architecture build problems for all the wrong reasons.
IA64 already added its own version of __node_random(), but the fact is,
there is nothing architectural about the function, and the original
commit was just badly done. Revert it, since no fix is forthcoming.Requested-by: Stephen Rothwell

ARCH_KMALLOC_MINALIGN was already defined in asm/mem-layout.h and so shouldn't
have been added to asm/cache.h as well, but rather altered in place.The commit that added it to asm/cache.h was:

We don't name our generic fsync implementations very well currently.
The no-op implementation for in-memory filesystems currently is called
simple_sync_file which doesn't make too much sense to start with,
the the generic one for simple filesystems is called simple_fsync
which can lead to some confusion.This patch renames the generic file fsync method to generic_file_fsync
to match the other generic_file_* routines it is supposed to be used
with, and the no-op implementation to noop_fsync to make it obvious
what to expect. In addition add some documentation for both methods.Signed-off-by: Christoph Hellwig

TS_POLLING set tells the scheduler an idle_task will poll
need_resched() to look for work.TS_POLLING clear tells resched_task() and wake_up_idle_cpu()
that the remote CPU's idle_task is now sleeping in idle,
and thus requires a reschedule interrupt notice work.Update the description of TS_POLLING to reflect how it works.

Rework the generic version of the numa_node_id() function to use the new
generic percpu variable infrastructure.Guard the new implementation with a new config option:
CONFIG_USE_PERCPU_NUMA_NODE_ID.
Archs which support this new implemention will default this option to 'y'
when NUMA is configured. This config option could be removed if/when all
archs switch over to the generic percpu implementation of numa_node_id().
Arch support involves:1) converting any existing per cpu variable implementations to use
this implementation. x86_64 is an instance of such an arch.
2) archs that don't use a per cpu variable for numa_node_id() will
need to initialize the new per cpu variable "numa_node" as cpus
are brought on-line. ia64 is an example.
3) Defining USE_PERCPU_NUMA_NODE_ID in arch dependent Kconfig--e.g.,
when NUMA is configured. This is required because I have
retained the old implementation by default to allow archs to
be modified incrementally, as desired.Subsequent patches will convert x86_64 and ia64 to use this implemenation.
