H A D | exception-64s.h | 7450f6f0 Wed Feb 29 17:52:01 CST 2012 Benjamin Herrenschmidt <benh@kernel.crashing.org> powerpc: Use the same interrupt prolog for perfmon as other interrupts
The perfmon interrupt is the sole user of a special variant of the interrupt prolog which differs from the one used by external and timer interrupts in that it saves the non-volatile GPRs and doesn't turn the runlatch on.
The former is unnecessary and the later is arguably incorrect, so let's clean that up by using the same prolog. While at it we rename that prolog to use the _ASYNC prefix.
