No point in having the open-coded PAGE_SIZE*8 when we already have an
aptly named macro.

Replace all shift rights/shift lefts by divide and multiply operations.
I've checked that this doesn't generate worse assembly and that shifts
are indeed continued to be used. PAGE_SHIFT + 3 is actually
BITS_PER_PAGE and is a constant integer expression so the compiler is
perfectly capable of figur
When working with percpu variables the only guarantee we need is that
the process is not preempted. So let's do this by using the more
idiomatic get_cpu_ptr/put_cpu_ptr rather than the more heavyweight
local_irq_disable. No functional changes.
