Fix issue reported by alc :
MIPS doesn't really need to use atomic_cmpset_int() in situations like
this because the software dirty bit emulation in trap.c acquires
the pmap lock. Atomics like this appear to be a carryover from i386
where the hardware-managed TLB might concurrently set the modified bit.

Fix the issue reported by alc:
pmap_page_wired_mappings() counts the number of pv entries for the
specified page that have the pv entry wired flag set to TRUE.
pmap_enter() correctly initializes this flag. However,
pmap_change_wiring() doesn't update the corresponding pv entry flag,
only the PTE. So, the count returned by pmap_page_wired_mappings()
will sometimes be wrong.
In the short term, the best fix would be to eliminate the pv entry
flag and use only the PTE. That flag is wasting non-trivial memory.
Remove pv_wired flag, and use PTE flag to count the wired mappings.

Implement a simple native VM86 backend for X86BIOS. Now i386 uses native

proven reliable for very long time and it is actually few times faster than
