[PATCH 0/1] Avoid oops on illegal VGA register access

[Simon Richter <Simon.Richter@hogyros.de>]

Hi,

this adds a way to avoid the illegal VGA accesses on non-x86 platforms by
letting these platforms report that VGA registers cannot be mapped.

This patch alone doesn't fully solve the problem, it also needs complementary
changes in vgaarb to actually report this, but since the interface is unchanged
and it is wrong to ignore the error code anyway, little coordination is needed
here.

Needs review from Intel whether this is the correct flow, and a decision on
whether this should be backported.
