    EDAC: Cleanup atomic_scrub mess · b01aec9b
    Borislav Petkov authored
    So first of all, this atomic_scrub() function's naming is bad. It looks
    like an atomic_t helper. Change it to edac_atomic_scrub().
    
    The bigger problem is that this function is arch-specific and every new
    arch which doesn't necessarily need that functionality still needs to
    define it, otherwise EDAC doesn't compile.
    
    So instead of doing that and including arch-specific headers, have each
    arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c
    for ifdeffery. Much cleaner.
    
    And we already are doing this with another symbol - EDAC_SUPPORT. This
    is also much cleaner than having CONFIG_EDAC enumerate all the arches
    which need/have EDAC support and drivers.
    
    This way I can kill the useless edac.h header in tile too.
