Thomas Gleixner d9a5c0a4e0 [PATCH] i386: Prevent early access to TSC to avoid crash on TSCless systems 
commit f9690982b8 removed the check for
cpu_khz from sched_clock(), which prevented early access to the TSC by
non obvious magic.

This is harmless as long as the CPU has a TSC. On TSCless systems this
results in an illegal instruction trap.

Replace tsc_disabled and tsc_unstable by tsc_enabled, which is only set
when the tsc is available and not unstable.
