Rusty Russell	56aa4129e8	cpumask: Use mm_cpumask() wrapper instead of cpu_vm_mask ... Makes code futureproof against the impending change to mm->cpu_vm_mask. It's also a chance to use the new cpumask_ ops which take a pointer (the older ones are deprecated, but there's no hurry for arch code).

Benjamin Herrenschmidt	f048aace29	powerpc/mm: Add SMP support to no-hash TLB handling ... This commit moves the whole no-hash TLB handling out of line into a new tlb_nohash.c file, and implements some basic SMP support using IPIs and/or broadcast tlbivax instructions. Note that I'm using local invalidations for D->I cache coherency. At worst, if another processor is trying to execute the same and has the old entry in its TLB, it will just take a fault and re-do the TLB flush locally (it won't re-do the cache flush in any case).
