Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer updates from Thomas Gleixner.

Various trivial conflict fixups in arch Kconfig due to addition of
unrelated entries nearby.  And one slightly more subtle one for sparc32
(new user of GENERIC_CLOCKEVENTS), fixed up as per Thomas.

* 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (31 commits)
  timekeeping: Fix a few minor newline issues.
  time: remove obsolete declaration
  ntp: Fix a stale comment and a few stray newlines.
  ntp: Correct TAI offset during leap second
  timers: Fixup the Kconfig consolidation fallout
  x86: Use generic time config
  unicore32: Use generic time config
  um: Use generic time config
  tile: Use generic time config
  sparc: Use: generic time config
  sh: Use generic time config
