| |
From: Borislav Petkov <bp@suse.de>
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")
