    [POWERPC] Generic BUG for powerpc · 73c9ceab
    Jeremy Fitzhardinge authored
    This makes powerpc use the generic BUG machinery.  The biggest reports the
    function name, since it is redundant with kallsyms, and not needed in general.
    
    There is an overall reduction of code, since module_32/64 duplicated several
    functions.
    
    Unfortunately there's no way to tell gcc that BUG won't return, so the BUG
    macro includes a goto loop.  This will generate a real jmp instruction, which
    is never used.
