| |
Commit a4b6a77b77ba4f526392612c2365797fab956014 ("module: fix symbol versioning with symbol prefixes") broke the MODVERSIONS loading of any module using memcmp (e.g. ipv6) on x86_32, as it's defined to __builtin_memcmp which is expanded by VMLINUX_SYMBOL_STR. Use __VMLINUX_SYMBOL_STR instead which doesn't expand the argument.
