Actually, I have one more general comment here. It would be really nice
if you could add those files that have nothing specific to blackfin moved
to include/asm-generic. That would probably include bug.h, current.h,
flat.h, hardirq.h, ioctls.h, {ipc,msg,sem,msg}buf.h, kmap_types.h, mman.h,
param.h, pci.h, poll.h, posix_types.h, scatterlist.h, semaphore.h,
socket.h, sockios.h, stat.h, termbits.h, termios.h, types.h, and unistd.h.

It doesn't really matter if you're the only user of the new files,
as long as they are generic enough to be used by every future port.
If the files are specific to nommu, 32bit or little-endian, then
they should probably have the respective name so the next person can
do it differently.

For unistd.h, it may be a good idea to leave space for a few syscall
numbers specific to architectures, so you could start the generic numbers
at 32 or so.

Of course nobody is forcing you do do that work, but the next person
trying to do will be really thankful.
