There seems to be no definition for arm here too. I literally meant
definition as '#define asmlinkage' not the usage of it. For arm it is none
so default defined in include/linux/linkage.h is used which is nothing
special and just extern 'C' declaration to avoid garbled naming of C++
linkage, thats it.
