[PATCH] NUMA-Q fixes 1/2

[Martin J. Bligh]

This simple patch just enables us to disable the TSC on the NUMA-Qs,
as they can't keep TSCs in sync across nodes.

Changes the proc-specific "CONFIG_X86_TSC" to "CONFIG_X86_HAS_TSC"
and then switches off that and CONFIG_X86_NUMAQ" later to recreate the
original "CONFIG_X86_TSC" option.

Only changes the config.in file, no effect on any machine except NUMA-Q.

Patch was written by someone who wants to remain anonymous ;-)

Please apply,
Thanks,

Martin.
