[CVE-2014-9090] x86_64, traps: Stop using IST for #SS

[Luis Henriques]

Following this email I am sending for review the CVE-2014-9090 fix
backports for both Lucid (2.6.32) and Precise (3.2.0).

I'm also CC'ing Debian mailing-lists, Moritz, Ben and Willy as these
backports could be of interest both to Debian and to the 2.6.32 and
3.2 stable kernels.
