Linus Torvalds fc1dc0d507 Updates for x86 timers: 
- Use the topology information of number of packages for making the
     decision about TSC trust instead of using the number of online nodes
     which is not reflecting the real topology.
 
   - Stop the PIT timer 0 when its not in use as to stop pointless emulation
     in the VMM.
 
   - Fix the PIT timer stop sequence for timer 0 so it truly stops both real
     hardware and buggy VMM emulations.

Pull x86 timer updates from Thomas Gleixner:

 - Use the topology information of number of packages for making the
   decision about TSC trust instead of using the number of online nodes
   which is not reflecting the real topology.

 - Stop the PIT timer 0 when its not in use as to stop pointless
   emulation in the VMM.

 - Fix the PIT timer stop sequence for timer 0 so it truly stops both
   real hardware and buggy VMM emulations.
