    parisc: move definition of PAGE0 to asm/page.h · 4a8a0788
    Rolf Eike Beer authored
    This was defined in asm/pdc.h which needs to include asm/page.h for
    __PAGE_OFFSET. This leads to an include loop so that page.h eventually will
    include pdc.h again. While this is no problem because of header guards, it is
    a problem because some symbols may be undefined. Such an error is this:
