    ARM: 7197/1: errata: Remove SMP dependency for erratum 751472 · ba90c516
    Dave Martin authored
    Activation conditions for a workaround should not be encoded in the
    workaround's direct dependencies if this makes otherwise reasonable
    configuration choices impossible.
    
    This patches uses the SMP/UP patching facilities instead to compile
    out the workaround if the configuration means that it is definitely
    not needed.
    
    This means that configs for buggy silicon can simply select
    ARM_ERRATA_751472, without preventing a UP kernel from being built
    or duplicatiing knowledge about when to activate the workaround.
    This seems the correct way to do things, because the erratum is a
    property of the silicon, irrespective of what the kernel config
    happens to be.
