The initialization code and macros are the same. So extracts it
and puts it into the driver. This is another step to follow
the driver model.
Those empty C files are there because the current Kbuild
requires Makefile to be present at those directories,
(due to arch/x86/Kbuild), which requires building some object
files. So the empty source files are there to produce empty
object files to satisfy this.

a hit to the context switch performance.
Per-arch asm implementations are provided for maximum performance.
