Modified files:
sys/i386/i386 trap.c
Log:
Push down Giant some in trap_pfault() so we don't grab Giant around
trap_fatal() to make restarting from panic's slightly easier. Before if
one did 'w 0 0' in ddb, the longjmp in ddb inside of trap_fatal() would
result in Giant being held (or recursed one level deeper) which led to
problems later on. You can now drop to teh debugger, do 'w 0 0', and
continue w/o a problem.
