[PATCH] powerpc: Fix PowerMac IRQ handling bug
The port to genirq & the new powerpc interrupt model in 2.6.18 introduced a bug in the legacy PowerMac PIC code (used on older machines) because of a typo potentially causing hangs due to interrupt storms. This fixes it, along with a performance issue causing us to do spurrious retriggers after masking an interrupt. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: "Antonino A.
