Linus Torvalds fea5f1e196 Revert "[PATCH] x86-64: Try multiple timer variants in check_timer" 
This reverts commit b026872601, which has
been linked to several problem reports with IO-APIC and the timer.
Machines either don't boot because the timer doesn't happen, or we get
double timer interrupts because we end up double-routing the timer irq
through multiple interfaces.

See for example

	http://lkml.org/lkml/2006/12/16/101
	http://lkml.org/lkml/2007/1/3/9
	http://bugzilla.kernel.org/show_bug.cgi?id=7789

about some of the discussion.

Patches to fix this cleanup exist (and have been confirmed to work fine
at least for some of the affected cases) and we'll revisit it for
2.6.21, but this late in the -rc series we're better off just reverting
the incomplete commit that caused the problems.
