Re: 2.6.24.7-rt16

[Thomas Gleixner <tglx@linutronix.de>]

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
