Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner:
"The timer department delivers this time:
- Support for cross clock domain timestamps in the core code plus a
first user. That allows more precise timestamping for PTP and
later for audio and other peripherals.
The ptp/e1000e patches have been acked by the relevant maintainers
and are carried in the timer tree to avoid merge ordering issues.
- Support for unregistering the current clocksource watchdog. That
lifts a limitation for switching clocksources which has been there
from day 1
- The usual pile of fixes and updates to the core and the drivers.
Nothing outstanding and exciting"
