This attempts to avoid splittings when it is not needed, that is when
vm_flags are same as new flags. The idea is from the <2.6.11 mlock_fixup
and others. This will provide base for the next madvise merging patch.

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!
