    powerpc: Fix various issues with return to userspace · 18b246fa

    We have a few problems when returning to userspace. This is a
    quick set of fixes for 3.3, I'll look into a more comprehensive
    rework for 3.4. This fixes:
    
     - We kept interrupts soft-disabled when schedule'ing or calling
    do_signal when returning to userspace as a result of a hardware
    interrupt.
    
     - Rename do_signal to do_notify_resume like all other archs (and
    do_signal_pending back to do_signal, which it was before Roland
    changed it).
    
     - Add the missing call to key_replace_session_keyring() to
    do_notify_resume().
