From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Currently userspace is allowed to feed in any king of garbage in the high bits of the mode flags/type, as are drivers when probing modes. Reject any mode with bogus flags/type. Hopefully this won't break any current userspace...
Unfortunately this breaks xf86-video-vmware which currently leaves the mode->type uninitialized :(. That code is inherited from the old gallium xorg state tracker. I don't know whether it has spread elsewhere but the symptoms are that the X server frequently dies failing to set screen resources, a very uninformative error.
I'll fix the xf86-video-vmware driver, but I guess we need to back out the mode->type check.
