Merge branch 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 timers updates from Thomas Gleixner:
 "This update contains:

   - The solution for the TSC deadline timer borkage, which is caused by
     a hardware problem in the TSC_ADJUST/TSC_DEADLINE_TIMER logic.

     The problem is documented now and fixed with a microcode update, so
     we can remove the workaround and just check for the microcode version.

     If the microcode is not up to date, then the TSC deadline timer is
     disabled. If the borkage is fixed by the proper microcode version,
     then the deadline timer can be used. In both cases the restrictions
     to the range of the TSC_ADJUST value, which were added as
     workarounds, are removed.

  - A few simple fixes and updates to the timer related x86 code"
