#     Pull timer updates from Thomas Gleixner:
#      "Time, timers and related driver updates:
#     
#        - Prevent unnecessary timer softirq invocations by extending the
#          tracking of the next expiring timer in the timer wheel beyond the
#          existing NOHZ functionality.
#     
#          The tracking overhead at enqueue time is within the noise, but on
#          sensitive workloads the avoidance of the soft interrupt invocation
#          is a measurable improvement.
#     
#        - The obligatory new clocksource driver for Ingenic X100 OST
#     
#        - The usual fixes, improvements, cleanups and extensions for newer
#          chip variants all over the driver space"
