We started testing 4.9 and see same problems as other people:
https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/tree/linux-4.9.y
Yes, this means we'll test 4.9 going forward. There are still some
failures due to missing configs, those should get fixed soon.
Best regards,
Pavel

ARM: Spectre-BHB workaround
comomit b9baf5c8c5c356757f4f9d8180b5e9d234065bc3 upstream.
Workaround the Spectre BHB issues for Cortex-A15, Cortex-A57,
Cortex-A72, Cortex-A73 and Cortex-A75. We also include Brahma B15 as
well to be safe, which is affected by Spectre V2 in the same ways as
Cortex-A15.
