'asmlinkage' macros are supposed to make symbol available
for calling from inline (or not) assembly.
'static' keyword is not compatible to it and breaks -flto
when gcc's LTO partitioner separates assembly definitions
from C definitions. This causes symbol resolution failures:
ld: /tmp/dosemu.bin.h8Y59G.ltrans0.ltrans.o: in function `stub_rep__':
<artificial>:(.text+0xe): undefined reference to `rep_movs_stos'
The changes turns 'asmlinkage' into exported symbol.
