From: Tom Zanussi <tom.zanussi@xxxxxxxxxxxxxxx>
Hello RT Folks!
This is the RT stable review cycle of patch 3.18.117-rt105-rc3.
This is -rc3, which is the same as -rc2 but adds 'locallock: provide
{get,put}_locked_ptr() variants' as was pointed out as missing by
Julia Cartwright and which I missed because my config was missing
CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU. Thanks for noticing and pointing
that out, Julia!
rc2 was the same set of patches as -rc1, but with the 'cherry-picked
from xxx' lines removed and replaced with the more standard [ Upstream
commit xxx ] form.
In addition to the applicable stable-rt patches not yet in the 3.18-rt
kernel, this set includes some patches needed to fix cross-compilation
build failures.
Please scream at me if I messed something up. Please test the
patches too.
The -rc release will be uploaded to kernel.org and will be
deleted when the final release is out. This is just a review
release (or release candidate).
The pre-releases will not be pushed to the git repository,
only the final release is.
If all goes well, this patch will be converted to the next
main release on 8/20/2018.
To build 3.18.117-rt105-rc3 directly, the following patches should be applied:
http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.18.tar.xz
http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.18.117.xz
http://www.kernel.org/pub/linux/kernel/projects/rt/3.18/patch-3.18.117-rt105-rc3.patch.xz
You can also build from 3.18.117-rt104 by applying the incremental patch:
http://www.kernel.org/pub/linux/kernel/projects/rt/3.18/incr/patch-3.18.117-rt104-rt105-rc3.patch.xz
Enjoy!
Tom
