* cpu_asm.S: This patch was co-developed with Eric Norum
<eric.norum@usask.ca>. It closes a one instruction window
on some m68k CPU cores. It fixes symptoms seen as:
1) No more `interrupt handler invoked twice for
a single interrupt'.
2) No more `lockup when mc68360 CPM and PIT interrupts
are at different levels'.
It does insert a little more overhead on machines without hardware
interrupt stacks but correctness has a price.
