Currently, the latest stable PREEMPT_RT patch is based off of 3.6.11.
As 3.6 is no longer supported by the stable Linux maintainers, this
release has been neglected, and its unfortunate that its the latest
of the -rt stable series.

I have decided to create a stable series that extends 3.6.11, and will
be of the form 3.6.11.x. I want to stress that this is a temporary
series, and will not be for long term. I will be pulling in patches from
3.4 and 3.8 stable releases as I find time.

I will host the 3.6.11.x patches at:

https://www.kernel.org/pub/linux/kernel/projects/rt/3.6/stable/

They will also be stored in the git repo:

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

branch: v3.6-stable

Again, I want to stress that this is not a long term stable release.
I will only support 3.6.11.x until 3.8-rt becomes stable. At which
time I will drop support for both 3.6.11.x as well as 3.6-rt.
