[PATCH] x86_64: Don't enable ATI apicmaintimer workaround when the machine has C2 or C3 Many laptops have problems with ticking the local APIC timer in C2/C3. The code added earlier to use it by default on ATI didn't really work for them. Don't enable it when the system supports C2/C3. This doesn't fix the problem fully, but at least it's not worse than before. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
