    [ARM] Optimise kernel->userspace exit code a little. · c28ac96b
    Russell King authored
    This improves interrupts and exceptions returning to user space
    by a few of cycles.  We change the requirements for
    *_restore_user_regs slightly so we can remove a few instructions.
    We also re-shuffle the code to handle pending work.
