[PARISC] Fix GSC graphics cards with 64MB regions
Make knapps work with its 64MB gfx card. I probably just broke another machine in the process, but assuming 64MB when 64MB aligned is probably safer than assuming 32MB all the time. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
