Modified files:
sys/conf param.c
sys/kern kern_lock.c
sys/sys kernel.h lock.h
sys/vm vm_map.h
Log:
For lockmgr mutex protection, use an array of mutexes that are allocated
and initialized during boot. This avoids bloating sizeof(struct lock).
As a side effect, it is no longer necessary to enforce the assumtion that
lockinit()/lockdestroy() calls are paired, so the LK_VALID flag has been
removed.
Idea taken from: BSD/OS.
