Modified: sys/i386/i386 pmap.c
sys/i386/include pmap.h
sys/kern kern_exec.c kern_exit.c subr_rlist.c
Log:
Performance optimizations. One of which was meant to go in before the
previous snap. Specifically, kern_exit and kern_exec now makes a
call into the pmap module to do a very fast removal of pages from the
address space. Additionally, the pmap module now updates the PG_MAPPED
and PG_WRITABLE flags. This is an optional optimization, but helpful
on the X86.
