From e6da269e0c81bfd4d63b7981e09235214abc829b Mon Sep 17 00:00:00 2001 From: jeff Date: Wed, 18 Jul 2007 20:46:06 +0000 Subject: - Remove the global definition of sched_lock in mutex.h to break new code and third party modules which try to depend on it. - Initialize sched_lock in sched_4bsd.c. - Declare sched_lock in sparc64 pmap.c and assert that we're compiling with SCHED_4BSD to prevent accidental crashes from running ULE. This is the sole remaining file outside of the scheduler that uses the global sched_lock.
