[PATCH] Remove page_table_lock from vma manipulations

After more careful consideration, I don't see any reasons why
page_table_lock is necessary for dealing with vmas. I found one spot in
swapoff, but it was easily changed to mmap_sem. I've beat on this code and
mjb has beat on this code with no problems. Here's the patch to remove it.

Feel free to poke holes in it.
