Subject: [PATCH] sched/core, ARM: Include linux/preempt.h from
 asm/mmu_context.h

arm's mmu_context.h uses preempt_enable_no_resched and but doesn't
include anything that would pull in the declaration.

If I start including <asm/mmu_context.h> from <linux/mmu_context.h>
without this, the build breaks.
