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

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

From: Michael Cree <mc...@orcon.net.nz>

commit a2fa3ccd7b43665fe14cb562761a6c3d26a1d13f upstream.

Currently we export SOCK_NONBLOCK to user space but that conflicts with
the definition from glibc leading to compilation errors in user programs
(e.g.  see Debian bug #658460).

The generic socket.h restricts the definition of SOCK_NONBLOCK to the
kernel, as does the MIPS specific socket.h, so let's do the same on
Alpha.
