    s390: remove 31 bit support · 5a79859a

    Remove the 31 bit support in order to reduce maintenance cost and
    effectively remove dead code. Since a couple of years there is no
    distribution left that comes with a 31 bit kernel.
    
    The 31 bit kernel also has been broken since more than a year before
    anybody noticed. In addition I added a removal warning to the kernel
    shown at ipl for 5 minutes: a960062e ("s390: add 31 bit warning
    message") which let everybody know about the plan to remove 31 bit
    code. We didn't get any response.
    
    Given that the last 31 bit only machine was introduced in 1999 let's
    remove the code.
    Anybody with 31 bit user space code can still use the compat mode.
