Hi,

For patches 11-16,

I've checked the building on x86, arm.
x86 shows no difference in floppy.o binary.

Compilation on arm tested (make rpc_defconfig).

I think that macro fd_outb from arm could be turned to
the static inline function, like on mips or m68k arches. However,
it's up to you if you want to keep the changes close to the
original structure.

Please address the warnings and resend the patches:

Everything else looks good to me. Thanks!
