This provides a uniform interface to enable/disable legacy fbdev support for modesetting drivers.
DRM_FBDEV_EMULATION is made available in the top level drm Kconfig. A driver that wants fbdev emulation using drm_fb_helper can enable this option.
Apart from 5 drivers (msm, tegra, imx, sti, i915), all enable fbdev emulation by default. For these drivers, if we explicitly disable fbdev emulation, the 'hope' is that we will cleanly bail out with an error. We set DRM_FBDEV_EMULATION to 'y' by default, since most drivers rely on it.

Ah I guess you can disregard some of my comments here. Since this was in-reply-to the old thread but step 1 wasn't I've read the patches out-of-order ;-) -Daniel
