#     
#     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"
