Modified files:
sys/arch/mips64/mips64: pmap.c
Log message:
Sync dcaches and invalidate icaches of all active CPUs of a pmap when
making a page executable. This prevents some icache inconsistencies that
could arise when a process modifies its code pages and begins executing
them while switching between CPUs. These inconsistencies caused process
crashes on multiprocessor IP27/IP30 systems under load.

Feedback from Miod, thanks!
