Commit b4fe945405e477cded91772b4fec854705443dd5 ("drm/radeon: Fix memory allocation failures in the preKMS command stream checking.") added a regression in that it completely tossed the get_unaligned() done by r300_scratch() which we added in commit 958a6f8ccb1964adc3eec84cf401c5baeb4fbca0 ("drm: radeon: Fix unaligned access in r300_scratch().").
Put it back.
