[patch] i386, numaq: enable TSCs again

[Ingo Molnar <mingo@elte.hu>]

Andi, Andrew, do you remember why we disabled TSCs on NUMAQ? It was 
slightly async between CPUs, right? In that case we should try the patch 
below.

From: Ingo Molnar <mingo@elte.hu>

enable TSCs on NUMAQ again. sched_clock() got improved and
the scheduler treats it as a per-CPU clock, so there should
be no issues from the slightly async TSCs on NUMAQ. Please
holler if this is wrong ...
