This was only added for the drm's fbdev emulation support, so that it would try harder to show the Oops. Unfortunately this never really worked reliably, and in practice ended up pushing the real Oops off the screen due to plentyfull locking, sleep-while-atomic and other issues. So we removed all that support from the fbdev emulation a...

Remove unnecessary dependencies in the include statements of the header file <linux/fb.h>. Several files throughout the kernel include the fbdev header, so reducing dependencies positively affects other subsystems as well. Also fix up nouveau and fbtft, which need backlight.h in some their source files. v2: * include backlight.h in fbtft (kernel test robot) Thomas Zimmermann (8): drm/nouveau: Include <linux/backlight.h> staging...

...d remove features, e.g. 50145474f6ef ("fbcon: remove soft scrollback code"). Now the problem is that most modern-ish drivers really only treat fbcon as an dumb kernel console until userspace takes over, and Oops printer for some emergencies. Looking at drm drivers and the basic vesa/efi fbdev drivers shows that only 3 drivers support any kind of acceleration: - nouveau, seems to be enabled by default - omapdrm, when a DMM remapper exists using remapper rewriting for y/xpanning - gma500, but that is getting deleted now for the GTT remapper trick, and the accelerated copyarea never s...
