Can't do that yet - that one is still called from regset.c:
arch/x86/kernel/fpu/regset.c: In function ‘xstateregs_set’: arch/x86/kernel/fpu/regset.c:135:10: error: implicit declaration of function ‘validate_user_xstate_header’ [-Werror=implicit-function-declaration] 135 | ret = validate_user_xstate_header(&xsave->header); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: some warnings being treated as errors
Maybe after the 5th patch which kills that usage too.
Gah, yes. I had the patches ordered differently and then failed to do a full step by step recompile after reshuffling them. Fixed localy.
