Subject: [PATCH v4 00/17] 64-bit friendly generic sched_clock()

This patchset adds support for 64 bit counters in the generic
sched_clock code and converts drivers over to use it. Based
on v3.11-rc1.

Changes since v3:
 * Move to use seqcount to fix issues with 64-bit cyc counters
 * Move to hrtimer to fix underflow/overflow errors in wraparound
   calculation
 * Use of 1 hour in clocks_calc_mult_shift
 * Converted over drivers in drivers/clocksource

Stephen Boyd (17):
  clocksource: Extract max nsec calculation into separate function
  sched_clock: Use seqcount instead of rolling our own
  sched_clock: Use an hrtimer instead of timer
  sched_clock: Add support for >32 bit sched_clock
  arch_timer: Move to generic sched_clock framework
  sched_clock: Remove sched_clock_func() hook
  clocksource: bcm2835: Switch to sched_clock_register()
  ocksource: dbx500-prcmu: Switch to sched_clock_register()
  clocksource: dw_apb_timer_of: Switch to sched_clock_register()
  clocksource: mxs_timer: Switch to sched_clock_register()
  clocksource: nomadik: Switch to sched_clock_register()
  clocksource: samsung_pwm_timer: Switch to sched_clock_register()
  clocksource: tegra: Switch to sched_clock_register()
  clocksource: time-armada-370-xp: Switch to sched_clock_register()
  clocksource: sirf: Switch to sched_clock_register() and use 64 bits
  clocksource: vf_pit_timer: Switch to sched_clock_register()
  sched_clock: Deprecate setup_sched_clock()
