[PATCH v3 0/9] video: screen_info cleanups

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

v3 changelog

No real changes, just rebased for context changes, and picked up the Acks.

This now conflicts with the ia64 removal and introduces one new dependency
on IA64, but that is harmless and trivial to deal with later.

v2 changelog

I refreshed the first four patches that I sent before with very minor
updates, and then added some more to further disaggregate the use
of screen_info:

 - I found that powerpc wasn't using vga16fb any more

 - vgacon can be almost entirely separated from the global
   screen_info, except on x86

 - similarly, the EFI framebuffer initialization can be
   kept separate, except on x86.

I did extensive build testing on arm/arm64/x86 and the normal built bot
testing for the other architectures.

Which tree should this get merged through?
