[GIT PULL] arm64 fixes for -rc1

From: Will Deacon

Date: Tue Oct 07 2025 - 04:28:23 EST


Hi Linus,

Please pull these arm64 fixes for -rc1 that address issues either found
or introduced during this merge window. The only one that isn't strictly
a fix is the kpti cleanup, as I ended up queuing it late due to some
inter-branch dependencies and wanted to give it some more time in -next.

Summary in the tag.

Cheers,

Will
