While working on arch/sh/include/asm/uaccess.h, I noticed
that one macro within this header is made harder to read because it
violates a coding style rule: space is missing after comma.

Fix it up.

This follows the sparc changes a439fe51.

Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.

This moves get_fs/set_fs() and friends in to asm/segment.h. The
mm_segment_t definition is likewise consolidated from the _32/_64 split.

This is prepatory groundwork for using the generic address space limit
and verification routines across mmu/nommu configs.

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!
