The memory behind ring_rptr can either be in ioremapped memory
or a vmalloc() normal kernel memory buffer.
However, the code unconditionally uses DRM_{READ,WRITE}32() (and thus
readl() and writel()) to access it.
Basically, if RADEON_IS_AGP then it's ioremap()'d memory else it's
vmalloc'd memory.
Adjust all of the ring_rptr access code as needed.
While we're here, kill the 'scratch' pointer in drm_radeon_private.
It's only used in the one place where it is initialized.
