Subject: [ANNOUNCE] 3.8.13-rt10

Dear RT Folks,

I'm pleased to announce the 3.8.13-rt10 release.

changes since v3.8.13-rt9:
- x86's mce timer was not scheduled properly due do missing µsec -> nsec
  conversation. Fix sent by Mike Galbraith.
- 32bit PowerPC missed to check _TIF_NEED_RESCHED and call
  preempt_schedule_irq() if needed. Fix sent by Priyanka Jain.

Known issues:

    - SLxB is broken on PowerPC, e500 based cpus. Can't repdroduce the
      problem on mpc5200 based board.

The delta patch against v3.8.13-rt9 is appended below and can be found here:

  https://www.kernel.org/pub/linux/kernel/projects/rt/3.8/incr/patch-3.8.13-rt9-rt10.patch.xz

The RT patch against 3.8.11 can be found here:

  https://www.kernel.org/pub/linux/kernel/projects/rt/3.8/patch-3.8.13-rt10.patch.xz
