2005-08-05	Rename the driver hooks in the DRM to something a little more	Eric Anholt
	understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating. Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)
2004-09-30	Remove DRM() macros from core ffb driver. DaveA says he'll make it compile	Jon Smirl
	someday.
2004-09-30	Lindent of core build. Drivers checked for no binary diffs. A few files	Jon Smirl
	weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included.
