In fact, my x86_64 allmodconfig build produces these:

arch/x86/crypto/sha1_ssse3_glue.c:43:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
 static asmlinkage void (*sha1_transform_asm)(u32 *, const char *, unsigned int);
 ^
arch/x86/crypto/sha256_ssse3_glue.c:56:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
 static asmlinkage void (*sha256_transform_asm)(const char *, u32 *, u64);
 ^
arch/x86/crypto/sha512_ssse3_glue.c:55:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
 static asmlinkage void (*sha512_transform_asm)(const char *, u64 *, u64);
 ^
mm/process_vm_access.c:422:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
 {
 ^

That last is added by commit 700d00f85598 ("mm/process_vm_access.c: mark
function as static") from the akpm-current tree.

So is "static asmlinkage" not allowed?
