Merge branch 'for-3.10' of git://linux-nfs.org/~bfields/linux

Pull nfsd fixes from Bruce Fields:
 "A couple minor fixes for the (new to 3.10) gss-proxy code.

  And one regression from user-namespace changes.  (XBMC clients were
  doing something admittedly weird--sending -1 gid's--but something that
  we used to allow.)"

* 'for-3.10' of git://linux-nfs.org/~bfields/linux:
  svcrpc: fix failures to handle -1 uid's and gid's
