asmlinkage Make __stack_chk_failed and memcmp visible
In LTO symbols implicitely referenced by the compiler need to be visible. Earlier these symbols were visible implicitely from being exported, but we disabled implicit visibility fo EXPORTs when modules are disabled to improve code size. So now these symbols have to be marked visible explicitely. Do this for __stack_chk_fail (with stack protector) and memcmp.
