Subject: [PATCH 1/2] staging/vboxvideo: Don't set FBINFO_MISC_ALWAYS_SETPAR

It's a debug hack flag useful to work around driver bugs. That's not a
good idea for a new driver. Especially for a new drm driver.

Aside: the fbdev support should probably be converted over to the new
generic fbdev support.

Subject: [PATCH 2/2] staging/xgifb: Needs to be converted to a drm driver

Although given the lack of progress since 2010, maybe time to ditch it
from staging outright?

Since Hans wants to destage vboxvideo this cycle probably best I merge
this through drm-misc? Just to make sure it's not lost.

Applied, thanks for your review.

I think 2/2 is directly staging material for you (somehow
get_maintainers.pl didn't add you to the cc: list, not sure why ...).

For the record I screwed up rebasing this one because it was in some patch
that also removed FBINFO_DEFAULT (which is 0, so pointless to set since
the structure is kzalloc'ed). Actually merged patch also removes
FBINFO_DEFAULT :-/ No real harm done though since as explained 0 doesn't
matter here.
