Functions __raw_writeq(), __raw_readq() are available for all
architectures. So let's use them.
The major architectures have these but not m68k, microblaze, nd32,
nios2, powerpc, sh, xtenza.
Just checking to be clear: This patch breaks compiling on these
platforms and you are withdrawing it (for now)?
Thanks,
Stefan
