updated patch, vs. 2.6.9

The previous patch disabled the LAPIC too early on SMP machines.
This updated patch, suggested by Ingo Molnar, does it later.

Also, the previous patch disabled the LAPIC if it was enabled,
while this patch disables it only if Linux forced it to be enabled.

Comment 8 Len Brown 2004-12-05 19:38:31 UTC
