Oddly, max_low_pfn/max_pfn end up being the number of pages in the system,
rather than the maximum PFN on ARM. This doesn't seem to cause any problems,
so just add a note about it.

ARM wasn't raising a SIGBUS with a siginfo structure. Fix
__do_user_fault() to allow us to use it for SIGBUS conditions, and arrange
for the sigbus path to use this.
We need to prevent the siginfo code being called if we do not have a user
space context to call it, so consolidate the "user_mode()" tests.
Thanks to Ian Campbell who spotted this oversight.

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!
