[PATCH 5.9 258/391] x86/mce: Allow for copy_mc_fragile symbol checksum to be generated

From: Greg Kroah-Hartman
Date: Tue Nov 03 2020 - 16:52:03 EST


From: Borislav Petkov <bp@xxxxxxx>

commit b3149ffcdb31a8eb854cc442a389ae0b539bf28a upstream.

Add asm/mce.h to asm/asm-prototypes.h so that that asm symbol's checksum
can be generated in order to support CONFIG_MODVERSIONS with it and fix:

WARNING: modpost: EXPORT symbol "copy_mc_fragile" [vmlinux] version \
generation failed, symbol will not be versioned.

For reference see:

4efca4ed05cb ("kbuild: modversions for EXPORT_SYMBOL() for asm")
334bb7738764 ("x86/kbuild: enable modversions for symbols exported from asm")
