Jann Horn ac26d1f74c x86/fpu: Use the correct exception table macro in the XSTATE_OP wrapper ... Commit 75045f77f7 ("x86/extable: Introduce _ASM_EXTABLE_UA for uaccess fixups") incorrectly replaced the fixup entry for XSTATE_OP with a user-#PF-only fixup. XRSTOR can also raise #GP if the xstate content is invalid, and _ASM_EXTABLE_UA doesn't expect that. Change this fixup back to _ASM_EXTABLE so that #GP gets fixed up.
