drivers/gpu/drm/i915/i915_sysfs.c:105:16: error: 'GEN7_L3LOG_SIZE'

Hi Tim,

FYI, kernel build failed on

tree:   git://sources.calxeda.com/kernel/linux.git ubuntu-quantal
head:   c07f1571f9b6e609109d50bd6ba2b2547e873614
commit: f22af270b676180993593f98bd23a51b9fc910d0 [94/299] drm/i915: l3 parity sysfs interface
config: x86_64-allmodconfig

These errors are then fixed by some later commit and only hurts bisectability. If you don't care about bisectability of your tree, please let me know. Thanks!
