Linus,

timers-urgent-for-linus
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
Thanks,
tglx
