    Hi stable maintainers,

    Please apply commit d1e420772cd1 ("x86/pkeys: Simplify PKRU update in signal frame") to the stable branches for 6.12 and later.

    This fixes a regression introduced in 6.13 by commit ae6012d72fa6 ("x86/pkeys: Ensure updated PKRU value is XRSTOR'd"), which was also backported in 6.12.5.

    Now queued up, thanks.

    Nope, this broke the build on 6.12.y and 6.15.y, so now dropped. How
    did you test this?

    Sorry, I forgot to say this depends on the preceding commit 64e54461ab6e ("x86/fpu: Refactor xfeature bitmask update code for sigframe XSAVE").

    Ben.

    Hi stable maintainers,

    Please apply commit d1e420772cd1 ("x86/pkeys: Simplify PKRU update in
    signal frame") to the stable branches for 6.12 and later.

    This fixes a regression introduced in 6.13 by commit ae6012d72fa6
    ("x86/pkeys: Ensure updated PKRU value is XRSTOR'd"), which was also
    backported in 6.12.5.
