Subject: Bug #7595: Avoid u32 overflows in radeon_check_and_fixup_offset().

The overflows could cause valid offsets to get rejected under some
circumstances, e.g. when the framebuffer resides at the very end of the card's
address space.

Subject: drm: i810_dma.c: fix pointer arithmetic for 64-bit target

First warning result from open-coded PTR_ERR,
the rest is caused by code like this:

*(u32 *) ((u32) buf_priv->kernel_virtual + used)

I've also fixed a missing PTR_ERR in i830_dma.c
