Subject: [PATCH v2 0/2] Introduce x86_get_cpufreq_khz()

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
