The asm-generic/xor.h header file is nasty and defines static functions
that are not inline. The header file is include by the ARM version of
asm/xor.h, which uses some but not all of the symbols defined there.
Marking the extraneous functions as __maybe_unused lets gcc drop them
without complaining.
Without this patch, building iop13xx_defconfig results in:
include/asm-generic/xor.h:696:34: warning: 'xor_block_8regs_p' defined but not used [-Wunused-variable]
include/asm-generic/xor.h:704:34: warning: 'xor_block_32regs_p' defined but not used [-Wunused-variable]

Commit e66eed651f ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h, which
uncovered several cases that had apparently relied on that rather
obscure header file dependency.
So this fixes things up a bit, using
grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')
to guide us in finding files that either need <linux/prefetch.h>
inclusion, or have it despite not needing it.
There are more of them around (mostly network drivers), but this gets
many core ones.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
