This is the start of the stable review cycle for the 5.4.184 release.
There are 18 patches in this series, all will be posted as a response
to this one. If anyone has any issues with these being applied, please
let me know.
Responses should be made by Fri, 11 Mar 2022 15:58:48 +0000.
Anything received after that time might be too late.
The whole patch series can be found in one patch at:
https://www.kernel.org/pub/linux/kernel/v5.x/stable-review/patch-5.4.184-rc1.gz
or in the git tree and branch at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-5.4.y
and the diffstat can be found below.
thanks,

On x86_64 (allnoconfig, gcc-10) this is the output:

If so, would not it be easier from a logistics point of view if ARM, ARM64 and x86 all get BHB mitigations within the same stable tag? Thanks -- Florian

I would have loved to have all three show up in the same stable releases, and for some kernels (5.10 and newer) that looks like it will happen. I was not happy with the 5.4 and older backports just yet enough to be able to add them to a -rc. Hopefully James and I can work through the issues and have them in a kernel soon. Note, Linus's tree, and these backports, all do break when using clang for arm32 and arm64, so that is an issue for many ARM users. Hopefully that can be resolved and when the fixes hit Linus's tree, I'll be glad to take them to stable releases. thanks, greg k-h
