Just wanted to send out my current Posix Alarm Timers queue for 
comment and review in the hopes of getting it into shape for
2.6.40.

Some background on the patches can be found here:
	https://lwn.net/Articles/429925/

New in this series:
* Added timekeeping_inject_sleeptime, which corrects CLOCK_BOOTTIME
  for arches that don't support read_persistent_clock().
* I've added a CAP_WAKE_ALARM capability to limit random applications
  from setting alarms in the last patch. This probably needs some
  careful review as it allows clock_nanosleep and timer_create to
  return -EPERM, which is new behavior.

thanks
-john
