[Intel-gfx] [PATCH 00/33] fbcon notifier begone v3!

[Daniel Vetter]

Hi all,

I think we're slowly getting there. Previous cover letters with more
context:

https://lists.freedesktop.org/archives/dri-devel/2019-May/218362.html

tldr; I have a multi-year plan to improve fbcon locking, because the
current thing is a bit a mess.

Cover letter of this version, where I detail a bit more the details
fixed in this one here:

https://lists.freedesktop.org/archives/dri-devel/2019-May/218984.html

Note that the locking plan in this one is already outdated, I overlooked a
few fun issues around any printk() going back to console_lock.

I think remaining bits:

- Ack from Daniel Thompson for the backlight bits, he wanted to check the
  big picture.

- Hash out actual merge plan.

I'm also cc'ing the entire pile to a lot more people on request.

Thanks, Daniel
