Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fixes from Thomas Gleixner:
"A small set of timer fixes:
- Evaluate the -ETIME condition correctly in the imx tpm driver
- Fix the evaluation order of a condition in posix cpu timers
- Use pr_cont() in the clockevents code to prevent ugly message
splitting
- Remove __current_kernel_time() which is now unused to prevent that
new users show up.
- Remove a stale forward declaration"
* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
clocksource/imx-tpm: Correct -ETIME return condition check
posix-cpu-timers: Ensure set_process_cpu_timer is always evaluated
timekeeping: Remove __current_kernel_time()
timers: Remove stale struct tvec_base forward declaration
clockevents: Fix kernel messages split across multiple lines
