[PATCH 1/3] fbmem: fix aperture overlapping check
fb_do_apertures_overlap is returning wrong value when one aperture
is completely whithin the other. Add generic ranges_overlap macro
(probably kernel.h candidate) and use it here.

Looks like registered_fb[] entry is pointing to (partially?) freed or
corrupted fb_info, but I can't see how this could be an effect of
remove_conflicting_framebuffers().

[PATCH 1/3] fbcon: Disable accelerated scrolling
So ever since syzbot discovered fbcon, we have solid proof that it's
full of bugs. And often the solution is to just delete code and 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
