Remove i915 driver sources from linux-core

Intel developers have stated, that their DRM development continues
elsewhere in some Linux kernel trees. This makes the code in drm.git
just dead weight. This removal allows further cleanup of compatibility
code.

shared-core and bsd-core are left untouched this time.

- * This is (we hope) the only really tricky part of gem. The goal
- * is fairly simple -- track which caches hold bits of the object
- * and make sure they remain coherent. A few concrete examples may
- * help to explain how it works. For shorthand, we use the notation
- * (read_domains, write_domain), e.g. (CPU, CPU) to indicate the
- * a pair of read and write domain masks.
- *
- * Case 1: the batch buffer
- *
- *	1. Allocated
- *	2. Written by CPU
- *	3. Mapped to GTT
- *	4. Read by GPU
- *	5. Unmapped from GTT
- *	6. Freed
- *
- *	Let's take these a step at a time
- *
- *	1. Allocated
- *		Pages allocated from the kernel may still have
- *		cache contents, so we set them to (CPU, CPU) always.
- *	2. Written by CPU (using pwrite)
- *		The pwrite function calls set_domain (CPU, CPU) and
- *		this function does nothing (as nothing changes)
- *	3. Mapped by GTT
- *		This function asserts that the object is not
- *		currently in any GPU-based read or write domains
- *	4. Read by GPU
- *		i915_gem_execbuffer calls set_domain (COMMAND, 0).
- *		As write_domain is zero, this function adds in the
- *		current read domains (CPU+COMMAND, 0).
- *		flush_domains is set to CPU.
- *		invalidate_domains is set to COMMAND
- *		clflush is run to get data out of the CPU caches
- *		then i915_dev_set_domain calls i915_gem_flush to
- *		emit an MI_FLUSH and drm_agp_chipset_flush
- *	5. Unmapped from GTT
- *		i915_gem_object_unbind calls set_domain (CPU, CPU)
- *		flush_domains and invalidate_domains end up both zero
- *		so no flushing/invalidating happens
- *	6. Freed
- *		yay, done
- *
- * Case 2: The shared render buffer
- *
- *	1. Allocated
- *	2. Mapped to GTT
- *	3. Read/written by GPU
- *	4. set_domain to (CPU,CPU)
- *	5. Read/written by CPU
- *	6. Read/written by GPU
- *
- *	1. Allocated
- *		Same as last example, (CPU, CPU)
- *	2. Mapped to GTT
- *		Nothing changes (assertions find that it is not in the GPU)
- *	3. Read/written by GPU
- *		execbuffer calls set_domain (RENDER, RENDER)
- *		flush_domains gets CPU
- *		invalidate_domains gets GPU
- *		clflush (obj)
- *		MI_FLUSH and drm_agp_chipset_flush
- *	4. set_domain (CPU, CPU)
- *		flush_domains gets GPU
- *		invalidate_domains gets CPU
- *		wait_rendering (obj) to make sure all drawing is complete.
- *		This will include an MI_FLUSH to get the data from GPU
- *		to memory
- *		clflush (obj) to invalidate the CPU cache
- *		Another MI_FLUSH in i915_gem_flush (eliminate this somehow?)
- *	5. Read/written by CPU
- *		cache lines are loaded and dirtied
- *	6. Read written by GPU
- *		Same as last GPU access
- *
- * Case 3: The constant buffer
- *
- *	1. Allocated
- *	2. Written by CPU
- *	3. Read by GPU
- *	4. Updated (written) by CPU again
- *	5. Read by GPU
- *
- *	1. Allocated
- *		(CPU, CPU)
- *	2. Written by CPU
- *		(CPU, CPU)
- *	3. Read by GPU
- *		(CPU+RENDER, 0)
- *		flush_domains = CPU
- *		invalidate_domains = RENDER
- *		clflush (obj)
- *		MI_FLUSH
- *		drm_agp_chipset_flush
- *	4. Updated (written) by CPU again
- *		(CPU, CPU)
- *		flush_domains = 0 (no previous write domain)
- *		invalidate_domains = 0 (no new read domains)
- *	5. Read by GPU
- *		(CPU+RENDER, 0)
- *		flush_domains = CPU
- *		invalidate_domains = RENDER
- *		clflush (obj)
- *		MI_FLUSH
- *		drm_agp_chipset_flush

-/** @file i915_gem_tiling.c
- *
- * Support for managing tiling state of buffer objects.
- *
- * The idea behind tiling is to increase cache hit rates by rearranging
- * pixel data so that a group of pixel accesses are in the same cacheline.
- * Performance improvement from doing this on the back/depth buffer are on
- * the order of 30%.
- *
- * Intel architectures make this somewhat more complicated, though, by
- * adjustments made to addressing of data when the memory is in interleaved
- * mode (matched pairs of DIMMS) to improve memory bandwidth.
- * For interleaved memory, the CPU sends every sequential 64 bytes
- * to an alternate memory channel so it can get the bandwidth from both.
- *
- * The GPU also rearranges its accesses for increased bandwidth to interleaved
- * memory, and it matches what the CPU does for non-tiled.  However, when tiled
- * it does it a little differently, since one walks addresses not just in the
- * X direction but also Y.  So, along with alternating channels when bit
- * 6 of the address flips, it also alternates when other bits flip --  Bits 9
- * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines)
- * are common to both the 915 and 965-class hardware.
- *
- * The CPU also sometimes XORs in higher bits as well, to improve
- * bandwidth doing strided access like we do so frequently in graphics.  This
- * is called "Channel XOR Randomization" in the MCH documentation.  The result
- * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address
- * decode.
- *
- * All of this bit 6 XORing has an effect on our memory management,
- * as we need to make sure that the 3d driver can correctly address object
- * contents.
- *
- * If we don't have interleaved memory, all tiling is safe and no swizzling is
- * required.
- *
- * When bit 17 is XORed in, we simply refuse to tile at all.  Bit
- * 17 is not just a page offset, so as we page an objet out and back in,
- * individual pages in it will have different bit 17 addresses, resulting in
- * each 64 bytes being swapped with its neighbor!
- *
- * Otherwise, if interleaved, we have to tell the 3d driver what the address
- * swizzling it needs to do is, since it's writing with the CPU to the pages
- * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the
- * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling
