Thoughts?

I can't say I approve keeping fbdev alive, but...

With fbdev emulation, every DRM driver is an fbdev driver too. So CONFIG_FB_DRIVER is somewhat misleading. Better add an option like CONFIG_FBCON_HW_SCROLLING and have it selected by the fbdev drivers that absolutely need HW acceleration. That option would then protect the rsp code.

Agreed that this option would be better and allow distros to disable the code that was reverted.

Best regards,
