This patch is rather big, but actually very straight-forward: it adds
a "agp dev" argument to DRM_IOREMAP(), DRM_IOREMAP_NOCACHE(), and
DRM_IOREMAPFREE() and then uses it in drm_memory.h to support
platforms where CPU accesses to the AGP space are not translated by
the GART (true for ia64 and alpha, not true for x86, I don't know
about the other platforms). On platforms where cant_use_aperture is
always false, this whole patch will look like a no-op. On ia64, it
works. Don't know about other platforms, but it should simplify
things for Alpha at least (and if it breaks a platform, I shall be
happy to work with the respective maintainer to get fix back to
working).
Thanks,
--david
