Pull x86 timer updates from Thomas Gleixner:
 "X86 timer specific updates:

   - Add TPAUSE based delay which allows the CPU to enter an optimized
     power state while waiting for the delay to pass. The delay is based
     on TSC cycles.

   - Add tsc_early_khz command line parameter to workaround the problem
     that overclocked CPUs can report the wrong frequency via CPUID.16h
     which causes the refined calibration to fail because the delta to
     the initial frequency value is too big. With the parameter users
     can provide an halfways accurate initial value"
