Merge branch 'for-3.5' of git://linux-nfs.org/~bfields/linux

Pull the rest of the nfsd commits from Bruce Fields:
 "... and then I cherry-picked the remainder of the patches from the
  head of my previous branch"

This is the rest of the original nfsd branch, rebased without the
delegation stuff that I thought really needed to be redone.

I don't like rebasing things like this in general, but in this situation
this was the lesser of two evils.
