[Intel-gfx] drm/i915 stable patches

[Daniel Vetter]

Dear stable team,

Please backport

commit 4615d4c9e27eda42c3e965f208a4b4065841498c

    drm/i915: Use MLC (l3$) for context objects

to all supported stable kernels. It's not just a performance
optimization, but seems to prevent gpu hangs, too.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=64073

Thanks, Daniel
