sh updates for 2.6.33-rc9

This simply hooks up TIF_SINGLESTEP around the hardware single-step enable/disable in addition to punting the step state down to tracehook_report_syscall_exit()/tracehook_signal_handler() in order to get the ptrace_notify() logic right, as reported by Mike Frysinger.

With any luck, this should it for 2.6.33.
