[PATCH] x86_64: Always use IO-APIC routing for timer.
I tested it on a couple of chipsets and it worked everywhere so it should be ok as default for now. So far I haven't done the great purge of the useless old check_timer code yet though. Can be overwritten with enable_8254_timer in the worst case Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
