No, just for the asmlinkage.  asmlinkage is used to mark functions which
are called from assembly.  Making them static generally means you can't
call them from assembly (unless you have asm() code in the .c file which
does, like our kernel_thread() implementation used to).

Ok, asmlinkage on ARM is a no-op, but it's useful cheap documentation to
mark which C functions get called from assembly.
