Applied to arm64 (for-next/fixes), thanks!

[1/2] arm64/head: Drop unnecessary pre-disable-MMU workaround
      https://git.kernel.org/arm64/c/2b504e162037
[2/2] arm64/head: Disable MMU at EL2 before clearing HCR_EL2.E2H
      https://git.kernel.org/arm64/c/34e526cb7d46

I added a Fixes tag and cc stable on the second patch, it goes all the
way to 6.3 (this should actually be 6.6 LTS).
