[Bug 451169] [NEW] Performance really dropped with 2.6.31-8-rt

[hanzomon4]

Public bug reported:

Performance has really taken a hit with the latest RT kernel... X-runs
are quite a bit more frequent and general performance of the desktop is
poor, it even hard locked on me forcing an ugly reboot. The general
performance of the stock kernel is fine however. I think this may have
something to do with the dynamic ticks feature being turned off. Only 3
things were changed according to the change log and only one is unique
to the rt kernel.

 [ Alessio Igor Bogani ]
  * Fix a package description error
  * Dynamic Ticks off by default

  [ Luke Yelavich ]
  * Update to Ubuntu mainline kernel v2.6.31-13.45.
  * Set CONFIG_X86_PAT=y as per mainline.
