On parisc, SHMLBA was defined to 0x00400000 (4MB) to reflect that we need to take care of our caches for shared mappings. But actually, we can map a file at any multiple address of PAGE_SIZE, so let us correct that now with a value of PAGE_SIZE for SHMLBA. Instead we now take care of this cache colouring via the constant SHM_COLOUR while we map shared pages.
