Pull timer fixes from Thomas Gleixner:
 "A set of small fixes:

   - regression fix for exynos_mct clocksource

   - trivial build fix for kona clocksource

   - functional one liner fix for the sh_tmu clocksource

   - two validation fixes to prevent (root only) data corruption in the
     kernel via settimeofday and adjtimex.  Tagged for stable"

* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  time: adjtimex: Validate the ADJ_FREQUENCY values
  time: settimeofday: Validate the values of tv from user
  clocksource: sh_tmu: Set cpu_possible_mask to fix SMP broadcast
  clocksource: kona: fix __iomem annotation
  clocksource: exynos_mct: Fix bitmask regression for exynos4_mct_write
