49c87d1447 /dev/mem was severely broken. If you tried to access outside managed memory, 
it would go into an infinite loop.  Instead, allow such I/O.

Also, implement mmap(2) for /dev/mem.

4c99916337 va_{start,end} audit: 
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Improved by comments from enami and christos -- thanks!

Heimdal/krb4/KAME changes already fed back, rest to follow.

Inspired by, but not not based on, OpenBSD.

1661137341 it's perfectly legal for pmap_extract() on the kernel pmap to not find 
anything mapped there, even though it never used to happen.  with today's
other changes it happens a lot now, so remove the debug check for it.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.
