Linus,

please pull the latest timers-core-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-core-for-linus

A rather large update for timers/timekeeping:

- compat syscall consolidation (Al Viro)

- Posix timer consolidation (Christoph Helwig / Thomas Gleixner)

- Cleanup of the device tree based initialization for clockevents and
clocksources (Daniel Lezcano)

- Consolidation of the FTTMR010 clocksource/event driver (Linus Walleij)

- The usual set of small fixes and updates all over the place.

Thanks,

tglx
