Pull timer fixes from Ingo Molnar: "This includes a fix for lockups caused by incorrect nsecs related cleanup, and a capabilities check fix for timerfd" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: jiffies: Revert bogus conversion of NSEC_PER_SEC to TICK_NSEC timerfd: Only check CAP_WAKE_ALARM when it is needed

jiffies: Revert bogus conversion of NSEC_PER_SEC to TICK_NSEC

2017-03-07T10:03:28Z

commit 93825f2ec736 converted NSEC_PER_SEC to TICK_NSEC because the author confused NSEC_PER_JIFFY with NSEC_PER_SEC. As a result, the calculation of refined jiffies got broken, triggering lockups. Fixes: 93825f2ec736 ("jiffies: Reuse TICK_NSEC instead of NSEC_PER_JIFFY") Reported-and-tested-by: Meelis Roos Signed-off-by: Frederic Weisbecker Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1488880534-3777-1-git-send-email-fweisbec@gmail.com Signed-off-by: Thomas Gleixner

sched/headers: Prepare to move cputime functionality from into

2017-03-02T07:42:39Z

Introduce a trivial, mostly empty header to prepare for the moving of cputime functionality out of sched.h. Update all code that relies on these facilities.

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:34Z

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.
