Ivybridge doesn't appear to have the same errata as Sandybridge; no
corruption was observed by setting it to more than the minimal correct
value. It's possible that we were simply lucky, since the URB entries
are 1024-bit on Ivybridge vs. 512-bit Sandybridge. Or perhaps the
underlying hardware issue is fixed.
Either way, we may as well program the minimum value since it's now
readily available, likely to be more efficient, and possibly more
correct.
v2: Use GEN7_SBE_* defines rather than GEN6_SF_*. (A copy and paste
mistake.) They're the same, but using the right names is better.

(cherry picked from commit 44aa2e15f6)
(This commit message was primarily written by Paul Berry, who explained
what's going on far better than I would have.)
Previous to this patch, we thought that the only restrictions on
3DSTATE_SF's URB read length were (a) it needs to be large enough to
read all the VUE data that the SF needs, and (b) it can't be so large
that it tries to read VUE data that doesn't exist. Since the VUE map
already tells us how much VUE data exists, we didn't bother worrying
about restriction (a); we just did the easy thing and programmed the
read length to satisfy restriction (b).
However, we didn't notice this erratum in the hardware docs: "[errata]
Corruption/Hang possible if length programmed larger than recommended".
Judging by the context surrounding this erratum, it's pretty clear that
it means "URB read length must be exactly the size necessary to read all
the VUE data that the SF needs, and no larger". Which means that we
can't program the read length based on restriction (b)--we have to
program it based on restriction (a).
The URB read size needs to precisely match the amount of data that the
SF consumes; it doesn't work to simply base it on the size of the VUE.
Thankfully, the PRM contains the precise formula the hardware expects.
Fixes random UI corruption in Steam's "Big Picture Mode", random terrain
corruption in PlaneShift, and Piglit's fbo-5-varyings test.

The swrast fragment program interpreter has trouble computing the
right texture LOD because it doesn't have easy access to input
derivatives. This causes the GLSL-based meta generate mipmap code
to fetch texels from the wrong mipmap level.
One possible fix would be to set the GL_TEXTURE_MIN/MAX_LOD parameters
to limit sampling from the right level. But let's just use the
_mesa_generate_mipmap() fallback since it's a lot faster than using
the fragment shader interpreter.

Previously, Mesa code assumed that glReadBuffer(GL_NONE) was only

quite clear that is should also be valid for the default framebuffer.
From section 18.2.1 ("Obtaining Pixels from the Framebuffer") of the
GL 4.3 spec:
"When READ_FRAMEBUFFER_BINDING is zero, i.e. the default
framebuffer, src must be one of the values listed in table 17.4,
including NONE."
Similar language exists in the GLES 3.0 spec, and in desktop GL all
the way back to ARB_framebuffer_object.
