v2:
- Rename x86_get_freq() to x86_get_cpufreq_khz() to make function
specific. (Suggested by Thomas Gleixner)
- Use cpu_feature_enabled(X86_FEATURE_TSC) instead of
cpu_has(&cpu_data(cpu), X86_FEATURE_TSC) to test feature.
(Suggested by Thomas Gleixner)
- Spell fixes. (Suggested by Thomas Gleixner)

v1:
- Introduce x86_get_freq(), hide detailed implemention from proc
routine.
- KVM uses x86_get_freq() to get CPU frequecy.

zhenwei pi (2):
x86/cpu: Introduce x86_get_cpufreq_khz()
KVM: x86: use x86_get_freq to get freq for kvmclock
