[PATCH] Add a function to handle interrupt affinity setting
Provide funtions to: - check, whether an interrupt can set the affinity - pin the interrupt to a given cpu Necessary for the ability to setup clocksources more flexible (e.g. use the different HPET channels per CPU) [akpm@osdl.org: alpha build fix] Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: john stultz <johnstul@us.ibm.com> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
