#     
#     Pull x86 timer updates from Thomas Gleixner:
#      "A series of commits to make the MSR derived CPU and TSC frequency more
#       accurate.
#     
#       It turned out that the frequency tables which have been taken from the
#       SDM are inaccurate because the SDM provides truncated and rounded
#       values, e.g. 83.3Mhz (83.3333...) or 116.7Mhz (116.6666...).
#     
#       This causes time drift in the range of ~1 second per hour (20-30
#       seconds per day). On some of these SoCs it's not possible to
#       recalibrate the TSC because there is no reference (PIT, HPET)
#       available.
#     
#       With some reverse engineering it was established that the possible
#       frequencies are derived from the base clock with fixed multiplier /
#       divider pairs.
#     
#       For the CPU models which have a known crystal frequency the kernel now
#       uses multiplier / divider pairs which bring the frequencies closer to
#       reality and fix the observed time drift issues"
