MFC 264128, 264129, 264130, 264135,
Fix TTB set operation for armv7. Perform sychronization (by "isb" barrier)
after TTB is set.
Fix TLB maintenance issues for armv6 and armv7.
- Add cpu_cpwait to comply with the convention.
- Add missing TLB invalidations, especially in pmap_kenter & pmap_kremove
with distinguishing between D and ID pages.
- Modify pmap init/bootstrap invalidations to ID, just to be safe.
- Fix TLB-inv and PTE_SYNC ordering.
Allocate per-cpu resources for doing pmap_zero_page() and pmap_copy_page().
This is performance enhancement rather than bugfix.
We don't support any ARM systems with an ISA bus and don't need a freelist
of memory to support ISA addressing limitations.
