[PATCH] percpu: convert global page accounting

Convert global page state accounting to use per-cpu storage

(I think this code remains a little buggy, btw.  Note how I do

	per_cpu(page_states, cpu).member += (delta);

This gets done at interrupt time and hence is assuming that
the "+=" operation on a ulong is atomic wrt interrupts on
all architectures. How do we feel about that assumption?)
