Modified files:
sys/i386/i386 db_interface.c
Log:
Moved stop/start code for other CPUs to near the beginning/end of
kdb_trap(). Stopping the other CPUs acts like locking them out, but
it wasn't done early enough or held long enough to prevent concurrent
accesses to shared data. In particular, the saved regs could be
clobbered.
