Desktop slowness (regression) caused by hashing change in 4.7

[Alexander Spitzer]

Hello all,

I'm experiencing some graphics issues due to commit 554828ee. I am
unsure if this is indeed a i915 problem. The relevant bugzilla is
below.

Who would be the best maintainer to contact about this?

Thanks!
