This patch (as1044) causes EHCI port handover for non-high-speed

The user might well unplug a USB device while the system is
suspended and then plug it back in before resuming.
A corresponding change is made to the core resume routine; now
high-speed root hubs will always be resumed when the system wakes up,
even if they were suspended before the system went to sleep. If this
weren't done then EHCI port handover wouldn't work, since it is called

SUNRPC: Invalidate the RPCSEC_GSS session if the server dropped the request
RFC 2203 requires the server to drop the request if it believes the
RPCSEC_GSS context is out of sequence. The problem is that we have no way
on the client to know why the server dropped the request. In order to avoid
spinning forever trying to resend the request, the safe approach is
therefore to always invalidate the RPCSEC_GSS context on every major
timeout.

V4L/DVB (7729): Fix VIDIOCGAP corruption in ivtv
Frank Bennett reported that ivtv was causing skype to crash. With help
from one of their developers he showed it was a kernel problem.
VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names
that are too long and does not truncate them so corrupts a few bytes of
the app data area.
Possibly the names also want trimming but for now this should fix the
corruption case.
