e087db510c Clean up struct screen_info (<linux/screen_info.h>)
struct screen_info has unaligned members, it needs to be packed.
In the process, fix the naming of some of the members, which don't
belong in this structure but are part of it anyway.

968de4f026 [PATCH] i386: Relocatable kernel support
This patch modifies the i386 kernel so that if CONFIG_RELOCATABLE is
selected it will be able to be loaded at any 4K aligned address below
1G.  The technique used is to compile the decompressor with -fPIC and
modify it so the decompressor is fully relocatable.  For the main
kernel relocations are generated.  Resulting in a kernel that is relocatable
with no runtime overhead and no need to modify the source code.

A reserved 32bit word in the parameters has been assigned
to serve as a stack so we figure out where are running.

89ec4c238e [PATCH] vesafb: Fix incorrect logo colors in x86_64
Bugzilla Bug 6299:

A pixel size of 8 bits produces wrong logo colors in x86_64.

The driver has 2 methods for setting the color map, using the protected
mode interface provided by the video BIOS and directly writing to the VGA
registers.  The former is not supported in x86_64 and the latter is enabled
only in i386.

Fix by enabling the latter method in x86_64 only if supported by the BIOS.
If both methods are unsupported, change the visual of vesafb to
STATIC_PSEUDOCOLOR.

2b4f2f4b01 [PATCH] vesafb: Drop blank hook
From: Bugzilla Bug 5351

"After resuming from S3 (suspended while in X), the LCD panel stays black .
 However, the laptop is up again, and I can SSH into it from another
machine.

I can get the panel working again, when I first direct video output to the
CRT output of the laptop, and then back to LCD (done by repeatedly hitting
Fn+F5 buttons on the Toshiba, which directs output to either LCD, CRT or
TV) None of this ever happened with older kernels."

This bug is due to the recently added vesafb_blank() method in vesafb.  It
works with CRT displays, but has a high incidence of problems in laptop
users.  Since CRT users don't really get that much benefit from hardware
blanking, drop support for this.

This makes it possible for boot code to use screen_info without dragging in
all of tty.h.
