# Merge: eac3411 1088c6e
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Mon Aug 13 18:28:19 2018 -0700
# 
#     Merge branch 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 timer updates from Thomas Gleixner:
#      "Early TSC based time stamping to allow better boot time analysis.
#     
#       This comes with a general cleanup of the TSC calibration code which
#       grew warts and duct taping over the years and removes 250 lines of
#       code. Initiated and mostly implemented by Pavel with help from various
#       folks"
