Back in the olden days we added support for using 64K pages to map the
SPU (Synergistic Processing Unit) local store on Cell, when the main
kernel was using 4K pages.
This was useful at the time because distros were using 4K pages, but
using 64K pages on the SPUs could reduce TLB pressure there.
However these days the number of Cell users is approaching zero, and
supporting this option adds unpleasant complexity to the memory
management code.
So drop the option, CONFIG_SPU_FS_64K_LS, and all related code.

from include/asm-powerpc. This is the result of a
mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
