[GIT pull] timekeeping upates for 4.20
From: Thomas Gleixner
Date: Wed Oct 24 2018 - 04:54:14 EST
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
The timers and timekeeping departement provides:
- Another large y2038 update with further preparations for providing the
y2038 safe timespecs closer to the syscalls.
- An overhaul of the SHCMT clocksource driver
- SPDX license identifier updates
- Small cleanups and fixes all over the place
Thanks,
tglx
