Merge branch 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 timer updates from Ingo Molnar:
"The main change in this tree is the reworking, fixing and extension of
the TSC frequency enumeration code (by Len Brown)"
* 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/tsc: Remove the unused check_tsc_disabled()
x86/tsc: Enumerate BXT tsc_khz via CPUID
x86/tsc: Enumerate SKL cpu_khz and tsc_khz via CPUID
x86/tsc_msr: Remove irqoff around MSR-based TSC enumeration
x86/tsc_msr: Add Airmont reference clock values
x86/tsc_msr: Correct Silvermont reference clock values
x86/tsc_msr: Update comments, expand definitions
x86/tsc_msr: Remove debugging messages
x86/tsc_msr: Identify Intel-specific code
Revert "x86/tsc: Add missing Cherrytrail frequency to the table"
