Merge branch 'resizex' (patches from Maciej)
Merge VT_RESIZEX fixes from Maciej Rozycki:
"I got to the bottom of the issue with VT_RESIZEX recently discussed
and came up with this small patch series, fixing an additional issue
that I originally thought might be broken VGA hardware emulation with
my laptop, which however turned out to be intertwined with the
original problem and also a regression introduced somewhat later.
The fix for that because the first patch, and then to make backporting
feasible I had to put a revert of the offending change from last
September next, followed by a proper fix for the framebuffer issue
that change had tried to address.
See individual change descriptions for details.
These have been verified with true VGA hardware (a Trident TVGA8900
ISA video adapter) using various combinations of `svgatextmode' and
`setfont' command invocations to change both the VT size and the font
size, and also switching between the text console and X11, both by
starting/stopping the X server and by switching between VTs.
All this to ensure bringing the behaviour of VGA text console back to
correct operation as it used to be with Linux 2.6.18"
