Linus Torvalds 9ea925c806 Updates for timers and timekeeping:
- Core:
 
 	- Overhaul of posix-timers in preparation of removing the
 	  workaround for periodic timers which have signal delivery
 	  ignored.
 
         - Remove the historical extra jiffie in msleep()
 
 	  msleep() adds an extra jiffie to the timeout value to ensure
 	  minimal sleep time. The timer wheel ensures minimal sleep
 	  time since the large rewrite to a non-cascading wheel, but the
 	  extra jiffie in msleep() remained unnoticed. Remove it.
 
         - Make the timer slack handling correct for realtime tasks.
 
 	  The procfs interface is inconsistent and does neither reflect
 	  reality nor conforms to the man page. Show the correct 0 slack
 	  for real time tasks and enforce it at the core level instead of
 	  having inconsistent individual checks in various timer setup
 	  functions.
 
         - The usual set of updates and enhancements all over the place.
 
   - Drivers:
 
         - Allow the ACPI PM timer to be turned off during suspend
 
 	- No new drivers
 
 	- The usual updates and enhancements in various drivers
