[PATCH] powerpc: mpic: minor optimization of ipi handler
From: Olof Johansson <hidden>
Date: 2007-10-19 18:44:37
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
Jeff Garzik pointed out that we don't actually have to lookup the mpic instance since it's passed in as the interrupt handler data for IPIs. Signed-off-by: Olof Johansson <redacted>
