Modified files:
sys/vm vm_map.c
Log:
Change vm_map_growstack to acquire and hold a read lock (instead of a write
lock) until it actually needs to modify the vm_map.
Note: it is legal to modify vm_map::hint without holding a write lock.
Submitted by: "Richard Seaman, Jr." <dick@tar.com> with minor changes
by myself.
