Marcelo,
Here is a trivial cleanup patch that replaces:
test_bit(X86_FEATURE_TSC, &boot_cpu_data.x86_capability)
w/ the cpu_has_tsc macro.
I believe this was originally by Brian Gerst for 2.5
thanks

This patch has a problem in the TSC not defined case in that
it access the PIT with out taking the required
locks. spin_lock_irq(&i8253_lock) is used to protect
the PIT...
