This is the start of the stable review cycle for the 5.8.1 release. There are 38 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 Wed, 12 Aug 2020 15:17:47 +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-5.8.1-rc1.g... or in the git tree and branch at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-5.8.y and the diffstat can be found below.

Results from Linaro’s test farm. No regressions on arm64, arm, x86_64, and i386.

Few warnings noticed while running kselftests on arm64 juno-r2 device 1 and 3 noticed on linux mainline tree 2 and 4 seems to be specific to arm64 juno platform.
