Subject: [ANNOUNCE] 3.4-rc2-rt2
Dear RT Folks,
I'm pleased to announce the 3.4-rc2-rt2 release.
Changes since 3.4-rc2-rt1:
* Fix cpumask fallout (Carsten)
* Convert omap wakeupgen_lock to raw
The delta patch to 3.4-rc2-rt1 is appended below and can be found
here:
http://www.kernel.org/pub/linux/kernel/projects/rt/3.4/incr/patch-3.4-rc2-rt1-rt2.patch.xz
The RT patch against 3.4-rc2 can be found here:
http://www.kernel.org/pub/linux/kernel/projects/rt/3.4/patch-3.4-rc2-rt2.patch.xz
The split quilt queue is available at:
http://www.kernel.org/pub/linux/kernel/projects/rt/3.4/patches-3.4-rc2-rt2.tar.xz
Enjoy,
tglx
