Merge tag 'x86_urgent_for_v6.9_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
- Fix CPU feature dependencies of GFNI, VAES, and VPCLMULQDQ
- Print the correct error code when FRED reports a bad event type
- Add a FRED-specific INT80 handler without the special dances that
need to happen in the current one
- Enable the using-the-default-return-thunk-but-you-should-not warning
only on configs which actually enable those special return thunks
- Check the proper feature flags when selecting BHI retpoline
mitigation
