    sparc: Remove old style signal frame support. · 5526b7e4

    Back around the same time we were bootstrapping the first 32-bit sparc
    Linux kernel with a SunOS userland, we made the signal frame match
    that of SunOS.
    
    By the time we even started putting together a native Linux userland
    for 32-bit Sparc we realized this layout wasn't sufficient for Linux's
    needs.
    
    Therefore we changed the layout, yet kept support for the old style
    signal frame layout in there.  The detection mechanism is that we had
    sys_sigaction() start passing in a negative signal number to indicate
    "new style signal frames please".
    
    Anyways, no binaries exist in the world that use the old stuff.  In
    fact, I bet Jakub Jelinek and myself are the only two people who ever
    had such binaries to be honest.
    
    So let's get rid of this stuff.
    
    I added an assertion using WARN_ON_ONCE() that makes sure 32-bit
    applications are passing in that negative signal number still.
