2007-07-18	drm: remove drm_u64_t, replace with uint64_t everwhere	Dave Airlie
	This might break something, stdint.h inclusion in drm.h maybe required but I'm not sure yet what platforms have it what ones don't.
2007-04-26	libdrm: remove HAVE_XORG_CONFIG_H and XFree86LOADER ifdef's.	George Sapountzis
	We no longer import libdrm in the xserver.
2006-03-15	Avoid walking off the end of the hash table. (Coverity report #465)	Adam Jackson

2006-02-20	Formatting cleanup, dead code removal. Remove N() namespacing macro,	Adam Jackson
	useless. Remove SIGIO handling functions as they're server-only and properly belong in libdri.
2005-11-30	Resync from Xorg head: conditional include of xorg-config.h	Adam Jackson

2005-11-28	fix mem leak in HashHash() (bug 5171)	Brian Paul

2005-01-30	Final pass of libdrm.so work:	Adam Jackson
	- Add $(DESTDIR) for distributors doing package creation - Remove OS-specific include path from build - Add /usr/include/drm for driver-kernel API - Install all of shared-core/*.h in /usr/include/drm - Rename xf86drm.h to libdrm.h since we're not X biased anymore - Include backwards compat for xf86drm.h name, with a warning - Fix libdrm source to account for drm.h living in /usr/include/drm
2001-04-09	First pass of XFree86 4.0.99.2 merge.	David Dawes

2001-03-13	Rest of MGA dualhead patch.	Gareth Hughes
