sys/uvm : uvm_map.c uvm_map.h
Log message:
Add locking for interrupt-safe maps (those that have the VM_MAP_INTRSAFE flag
set). Since we cannot sleep in that case, use a mutex instead of an rwlock.
This is ok as the more complex code paths in the uvm code are not entered
for interrupt-safe maps as paging isn't allowed in those maps.
