Subject: [ANNOUNCE] 3.0.33-rt54


Dear RT Folks,

I'm pleased to announce the 3.0.33-rt54 stable release.


You can get this release via the git tree at:

  git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git

  Head SHA1: f539529bbaf7bbd5b45d71e72bd49cbe33ef7ad0


Or to build 3.0.33-rt54 directly, the following patches should be applied:

  http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.0.tar.xz

  http://www.kernel.org/pub/linux/kernel/v3.0/patch-3.0.33.xz

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.0/patch-3.0.33-rt54.patch.xz


You can also build from 3.0.33-rt53 by applying the incremental patch:

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.0/incr/patch-3.0.33-rt53-rt54.patch.xz



Enjoy,
