[PATCH] ppc32: fix destroy_context() race condition
Fix for a race condition when a task gets preempted by another task while
executing the destroy_context(...) in a FEW_CONTEXTS environment.
mm->context == NO_CONTEXT but the context_map may indicate all contexts are
in use.
The solution to this problem is to disable kernel preemption while
destroying a MMU context.
