Peter Zijlstra f342552b91 powerpc/mm: Make hpte_need_flush() safe for preemption
hpte_need_flush() might be called outside of a preempt section
when manipulating the kernel page tables, so we need to use the
appopriate variants of per-cpu variable accesses. There should
be no risk of being in the middle of a batch and a context
switch will flush any pending batch.

[Patch extracted from a larger patch in Peter's preemptible
 mmu_gather series]
