SubjectRe: 2.6.24.7-rt16
We are pleased to announce the 2.6.24.7-rt17 tree, which can be
downloaded from the location:

http://rt.et.redhat.com/download/

Information on the RT patch can be found at:

http://rt.wiki.kernel.org/index.php/Main_Page

This is a bugfix update:

- use the correct version of the ppc64 percpu patch
pointed out by Chirag Jog

to build a 2.6.24.7-rt17 tree, the following patches should be applied:

http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.tar.bz2
http://kernel.org/pub/linux/kernel/v2.6/patch-2.6.24.7.bz2
http://rt.et.redhat.com/download/patch-2.6.24.7-rt17.bz2

And like always, Steven's RT version of Matt Mackall's ketchup will get this
for you nicely:

http://people.redhat.com/srostedt/rt/tools/ketchup-0.9.8-rt3

As usual the broken out patches are also available.

Thanks,

tglx
