Modified files:
sys/i386/i386 swtch.s
Log:
Use a critical region to protect saving of the npx state in savectx().
Not doing this was fairly harmless because savectx() is only called
for panic dumps and the bug could at worse reset the state.
savectx() is still missing saving of (volatile) debug registers, and
still isn't called for core dumps.
