	syssrc/sys/arch/mips/mips: pmap.c

Log Message:
Fix race between pmap_enter() and pagedaemon.  If we are low on memory and
pmap_enter() cannot allocate the segmap return failure if PMAP_CANFAIL
instead of sleeping.  Otherwise panic.  Both alpha and i386 do this.  Do
not pmap_enter_pv() until after this is done so the data structures are
not partially allocated.  This should prevent pmap_page_protect() from
getting stuck when called from pagedaemon.
