[PATCH v3 1/1] x86/kbuild: enable modversions for symbols exported from asm
Commit 4efca4ed ("kbuild: modversions for EXPORT_SYMBOL() for asm") adds
modversion support for symbols exported from asm files. Architectures
must include C-style declarations for those symbols in asm/asm-prototypes.h
in order for them to be versioned.
Add these declarations for x86, and an architecture-independent file that
can be used for common symbols.
With f27c2f6 reverting 8ab2ae6 ("default exported asm symbols to zero") we
produce a scary warning on x86, this commit fixes that.

[PATCH v3 1/1] x86/kbuild: enable modversions for symbols exported from asm
Commit 4efca4ed ("kbuild: modversions for EXPORT_SYMBOL() for asm") adds
modversion support for symbols exported from asm files. Architectures
must include C-style declarations for those symbols in asm/asm-prototypes.h
in order for them to be versioned.
Add these declarations for x86, and an architecture-independent file that
can be used for common symbols.
With f27c2f6 reverting 8ab2ae6 ("default exported asm symbols to zero") we
produce a scary warning on x86, this commit fixes that.
