#     Pull timer fixes from Thomas Gleixner:
#      "Two fixes for timers:
#     
#        - Use the ALARM feature check in the alarmtimer core code insted of
#          the old method of checking for the set_alarm() callback.
#     
#          Drivers can have that callback set but the feature bit cleared. If
#          such a RTC device is selected then alarms wont work.
#     
#        - Use a proper define to let the preprocessor check whether Hyper-V
#          VDSO clocksource should be active.
#     
#          The code used a constant in an enum with #ifdef, which evaluates to
#          always false and disabled the clocksource for VDSO"
