The old /proc interfaces were never updated to use loff_t, and are just
generally broken. Now, we should be using the seq_file interface for
all of the proc files, but converting the legacy functions is more work
than most people care for and has little upside..
But at least we can make the non-LFS rules explicit, rather than just
insanely wrapping the offset or something.

Now that RCU applied on 'struct file' seems stable, we can place f_rcuhead
in a memory location that is not anymore used at call_rcu(&f->f_rcuhead,
file_free_rcu) time, to reduce the size of this critical kernel object.
The trick I used is to move f_rcuhead and f_list in an union called f_u
The callers are changed so that f_rcuhead becomes f_u.fu_rcuhead and f_list
becomes f_u.f_list

This patch fixes bug titled "sunrpc as module and bad proc/sys link count"
reported by Jiri Slaby.
The problem was, that only proc_dir_entry->nlink was updated and the
corresponding inode->i_nlink was not. The fix is to implement the
inode->getattr() method, and update i_nlink (if necessary).
A quick audit of proc code shows that no other attribute changes after
creation.

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!
