Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this shifts into the sign bit. Instead use (1U << 31) which gets the expected result.
This fix is not ideal as it assumes a 32 bit int, but does fix the issue for most cases.
A similar change was made in OpenBSD.

Update to DRM CVS as of 2006-04-09. The most notable new feature is the updated Radeon memmap code, which with a new DDX driver and DRI drivers should fix long-term stability issues with Radeons. Also adds support for r200's ATI_fragment_shader, r300 texrect support and texture caching fixes, i915 vblank support and bugfixes, and new PCI IDs.

Update DRM to CVS snapshot as of 2005-11-28. Notable changes: - S3 Savage driver ported. - Added support for ATI_fragment_shader registers for r200. - Improved r300 support, needed for latest r300 DRI driver. - (possibly) r300 PCIE support, needs X.Org server from CVS. - Added support for PCI Matrox cards. - Software fallbacks fixed for Rage 128, which used to render badly or hang. - Some issues reported by WITNESS are fixed. - i915 module Makefile added, as the driver may now be working, but is untested. - Added scripts for copying and preprocessing DRM CVS for inclusion in the kernel. Thanks to Daniel Stone for getting me started on that.

Update to DRM CVS as of 2005-04-12, bringing many changes: - Split core DRM routines back into their own module, rather than using the nasty templated system like before. - Development-class R300 support in radeon driver (requires userland pieces, of course). - Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the testbox). Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others. - i915 driver files, which just need to get drm_drv.c fixed to allow attachment to the drmsub device. Covers i830 through i915 integrated graphics. - savage driver files, which should require minimal changes to work. Covers the Savage3D, Savage IX/MX, Savage 4, ProSavage. - Support for color and texture tiling and HyperZ features of Radeon.

Update the DRM to latest from DRI CVS. This is approximately the version included in XFree86 4.3, but includes some fixes. Notable changes include Radeon 8500-9100 support, PCI Radeon/Rage 128 support, transform & lighting support for Radeons, and vblank syncing support for r128, radeon, and mga. The gamma driver was removed due to lack of any users.
