[PATCH] x86_64: Add option to disable timer check
This works around the too fast timer seen on some ATI boards. I don't feel confident enough about it yet to enable it by default, but give users the option. Patch and debugging from Christopher Allen Wing <>, with minor tweaks (renamed the option and documented it) Signed-off-by: Andi Kleen <> Signed-off-by: Andrew Morton <> Signed-off-by: Linus Torvalds <>
