commit 334bb773876403eae3457d81be0b8ea70f8e4ccc upstream.
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.
