Neither of these need to be backported to the v6.12.y stable tree. In the v6.12.y stable tree CONFIG_ARM64_SME depends on BROKEN, and these patches only matter when CONFIG_ARM64_SME=y. I think we should leave that BROKEN in the v6.12.y stable tree given that suddenly enabling SME for distros could cause all sorts of surprises. If you are going to backport patches I have written, please CC me on those backports.
