Subject: [PATCH 3.11 247/272] NFSv4.2: Fix a mismatch between Linux labeled NFS and the NFSv4.2 spec

3.11.10.1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <Trond.Myklebust@...app.com>

commit f3f5a0f8cc40b942f4c0ae117df82eeb65f07d4d upstream.

In the spec, the security label attribute id is '80', which means that
it should be bit number 80-64 == 16 in the 3rd word of the bitmap.

Fixes: 4488cc96c581: NFS: Add NFSv4.2 protocol constants
