Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer update from Thomas Gleixner:
"New defines for the compat time* types so they can be shared between
32bit and 64bit builds. Not used yet, but merging them now allows the
actual conversions to be merged through different maintainer trees
without dependencies
We still have compat interfaces for 32bit on 64bit even with the new
2038 safe timespec/val variants because pointer size is different. And
for the old style timespec/val interfaces we need yet another 'compat'
interface for both 32bit native and 32bit on 64bit"
