Benjamin Herrenschmidt 281ab031a8 [PATCH] radeon drm: fix agp aperture map offset 
This finally fixes the radeon memory mapping bug that was incorrectly
fixed by the previous patch.  This time, we use the actual vram size as
the size to calculate how far to move the AGP aperture from the
framebuffer in card's memory space.

If there are still issues with this patch, they are due to bugs in the X
driver that I'm working on fixing too.

/* 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
* 1.17- Add initial support for R300 (3D).
* 1.18- Add support for GL_ATI_fragment_shader, new packets
* R200_EMIT_PP_AFS_0/1, R200_EMIT_PP_TXCTLALL_0-5 (replaces
* R200_EMIT_PP_TXFILTER_0-5, 2 more regs) and R200_EMIT_ATF_TFACTOR
* (replaces R200_EMIT_TFACTOR_0 (8 consts instead of 6)
* 1.19- Add support for gart table in FB memory and PCIE r300
