    sparc64: Set %l4 properly on trap return after handling signals. · d1f1f98c
    David S. Miller authored
    If we did some signal processing, we have to reload the pt_regs
    tstate register because it's value may have changed.
    
    In doing so we also have to extract the %pil value contained in there
    anre load that into %l4.
    
    This value is at bit 20 and thus needs to be shifted down before we
    later write it into the %pil register.
    
    Most of the time this is harmless as we are returning to userspace
    and the %pil is zero for that case.
