sh updates for 2.6.33-rc8

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.
