Modified files:
sys/i386/isa ipl.s
sys/i386/i386 trap.c
Log:
- Change ast() to take a pointer to a trapframe like other architectures.
- Don't use an atomic operation to update cnt.v_soft in ast(). This is
the only place the variable is written to, and sched_lock is always
held when it is written, so it is already protected and the mutex release
of sched_lock asserts a memory barrier that ensures the value will be
updated in a timely fashion.
