[GIT PULL] sh updates for 2.6.33-rc8

[Paul Mundt <lethal@xxxxxxxxxxxx>]

This fixes up a number of crashes both with the unwinder and with booting
from USB mass storage on certain CPUs. While the unwinder fixups aren't
technically regression fixes, they address a fairly long-standing set of
bugs. The HCD changes fix a fairly long-standing regression that was only
recently reported.
