Both, no scaling with xv either.

Completely disable 2D acceleration on Broadwell
As tedu@ reported (and some pople on misc@ confirmed) partly disabling 2D acceleration on Broadwell made X unstable. It really looks like the alternative BLT path isn't well tested and therefore buggy. So here is a diff that disables 2D acceleration completely. Those who don't care about suspend/resume can still enable it if they want. 3D acceleration should continue to work. ok?
