fix i915 <gen6 hardware with kernel >=3.14

A code change in kernel 3.14 requires fixing mesa for certain i915 hardware (gen4 and 5).

Even master still isn't fixed, the proposed patch applies cleanly to 10.1.1 and fixes the problem for me.
Comment 1 Andreas Sturmlechner gentoo-dev 2014-05-01 13:05:08 UTC
fix has gone upstream, let's patch it downstream?
Comment 2 Andreas Sturmlechner gentoo-dev 2014-05-05 22:55:31 UTC
not fixed in upstream mesa-10.1.2
Comment 3 Andreas Sturmlechner gentoo-dev 2014-05-10 15:22:44 UTC
still not fixed in upstream mesa-10.1.3
Comment 4 Chí-Thanh Christopher Nguyễn gentoo-dev 2014-05-12 07:14:41 UTC
Then your issue that you are seeing is not fdo #75723, as this has already been fixed in 10.1 branch and is included in mesa-10.1.2

Oh, I was wondering how that patch did still apply here when it should have been backported already, but in fact an entirely different patch made it upstream instead of the one from the bug. Sorry for the noise then, works for me now (I'm not often testing kernels above 3.4.9999, just to see if by some chance my pet bug(s) have been fixed).
