Subject: [ 30/32] drm/gma500: Increase max resolution for mode setting

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Patrik Jakobsson <patrik.r.jakobsson@...il.com>

commit cbbd379aa43890f36da934f5af619d2fb8ec3d87 upstream.

By having a higher max resolution we can now set up a virtual
framebuffer that spans several monitors. 4096 should be ok since we're
gen 3 or higher and should be enough for most dual head setups.
