Module Name:    src

Modified Files:
        src/sys/arch/m68k/m68k: pmap_68k.c

Log Message:
A few things done while chasing down mod/ref bugs:
- pmap_remove_mapping() can now take pointer to the vm_page, saving a
  lookup and allowing some additional assertions when it's available
  (which is "frequently" in this implementation).
- All of the PTE load/store/modify-in-PT helpers now are decorated
  with "volatile".
- Don't bother with atomic_load / atomic_store.
- Simplify pmap_testbit() and pmap_changebit().
- Add more PMAP_DEBUG-only mod/ref tests (including a test that validates
  MMU beavior that was used to find a Qemu m68k emulator bug).
