Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+	  Kernel-level support for the Direct Rendering Infrastructure (DRI)

+************************************************************

+*     http://dri.sourceforge.net/                          *
+************************************************************
+
+The Direct Rendering Manager (drm) is a device-independent kernel-level
+device driver that provides support for the XFree86 Direct Rendering
+Infrastructure (DRI).
+
+The DRM supports the Direct Rendering Infrastructure (DRI) in four major
+ways:
+
+    1. The DRM provides synchronized access to the graphics hardware via
+       the use of an optimized two-tiered lock.
+
+    2. The DRM enforces the DRI security policy for access to the graphics
+       hardware by only allowing authenticated X11 clients access to
+       restricted regions of memory.
+
+    3. The DRM provides a generic DMA engine, complete with multiple
+       queues and the ability to detect the need for an OpenGL context
+       switch.
+
+    4. The DRM is extensible via the use of small device-specific modules
+       that rely extensively on the API exported by the DRM module.
+
+
+Documentation on the DRI is available from:
+    http://precisioninsight.com/piinsights.html
+
+For specific information about kernel-level support, see:
+
+    The Direct Rendering Manager, Kernel Support for the Direct Rendering
+    Infrastructure

+/* Interface history:
+ *
+ * 1.1 - ??
+ * 1.2 - Add vertex2 ioctl (keith)
+ *     - Add stencil capability to clear ioctl (gareth, keith)
+ *     - Increase MAX_TEXTURE_LEVELS (brian)
+ * 1.3 - Add cmdbuf ioctl (keith)
+ *     - Add support for new radeon packets (keith)
+ *     - Add getparam ioctl (keith)
+ *     - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
+ * 1.4 - Add scratch registers to get_param ioctl.
+ * 1.5 - Add r200 packets to cmdbuf ioctl
+ *     - Add r200 function to init ioctl
+ *     - Add 'scalar2' instruction to cmdbuf
+ * 1.6 - Add static GART memory manager
+ *       Add irq handler (won't be turned on unless X server knows to)
+ *       Add irq ioctls and irq_active getparam.
+ *       Add wait command for cmdbuf ioctl
+ *       Add GART offset query for getparam
+ * 1.7 - Add support for cube map registers: R200_PP_CUBIC_FACES_[0..5]
+ *       and R200_PP_CUBIC_OFFSET_F1_[0..5].
+ *       Added packets R200_EMIT_PP_CUBIC_FACES_[0..5] and
+ *       R200_EMIT_PP_CUBIC_OFFSETS_[0..5].  (brian)
+ * 1.8 - Remove need to call cleanup ioctls on last client exit (keith)
+ *       Add 'GET' queries for starting additional clients on different VT's.
+ * 1.9 - Add DRM_IOCTL_RADEON_CP_RESUME ioctl.
+ *       Add texture rectangle support for r100.
+ * 1.10- Add SETPARAM ioctl; first parameter to set is FB_LOCATION, which
+ *       clients use to tell the DRM where they think the framebuffer is 
+ *       located in the card's address space
+ * 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color
+ *       and GL_EXT_blend_[func|equation]_separate on r200
+ * 1.12- Add R300 CP microcode support - this just loads the CP on r300
+ *       (No 3D support yet - just microcode loading)
+ * 1.13- Add packet R200_EMIT_TCL_POINT_SPRITE_CNTL for ARB_point_parameters
+ *     - Add hyperz support, add hyperz flags to clear ioctl.
+ * 1.14- Add support for color tiling
+ *     - Add R100/R200 surface allocation/free support
+ * 1.15- Add support for texture micro tiling
+ *     - Add support for r100 cube maps
+ * 1.16- Add R200_EMIT_PP_TRI_PERF_CNTL packet to support brilinear
+ *       texture filtering on r200
