Merge branch 'clockevents/4.0-rc1' of... 

Merge branch 'clockevents/4.0-rc1' of git://git.linaro.org/people/daniel.lezcano/linux

 into timers/urgent

Pull clockevents driver fixes from Daniel Lezcano:

  - Fix the Kconfig to prevent the asm9260 timer to be compiled with
    allyesconfig with sparc/sparc64 (Daniel Lezcano)

  - Reorder the mtk driver init sequence in order to prevent a potential race
    when the clock is registered before the irq handler is set (Matthias Brugger)

  - Fix a section mismatch for the pxa driver (Robert Jarzmik)
