5e8ddcbe86 Video mode probing support for the new x86 setup code
Video mode probing for the new x86 setup code.  This code breaks down
different drivers into modules.  This code deliberately drops support
for a lot of the vendor-specific mode probing present in the assembly
version, since a lot of those probes have been found to be stale in
current versions of those chips -- frequently, support for those modes
have been dropped from recent video BIOSes due to space constraints,
but the video BIOS signatures are still the same.

However, additional drivers should be extremely straightforward to plug
in, if desirable.

1d67953f2b Use a new CPU feature word to cover features that are spread around
Some Intel features are spread around in different CPUID leafs like 0x5,
0x6 and 0xA.  Make this feature detection code common across i386 and
x86_64.

Display Intel Dynamic Acceleration feature in /proc/cpuinfo. This feature
will be enabled automatically by current acpi-cpufreq driver.

Refer to Intel Software Developer's Manual for more details about the feature.

Thanks to hpa (H Peter Anvin) for the making the actual code detecting the
scattered features data-driven.

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.

de32e04175 x86 Kconfig: change X86_MINIMUM_CPU_MODEL to X86_MINIMUM_CPU_FAMILY
The X86_MINIMUM_CPU_MODEL name isn't really right, so change it to
X86_MINIMUM_CPU_FAMILY.  Also, the default minimum should be 3, not 0.

ec481536b1 Unify the CPU features vectors between i386 and x86-64
Unify the handling of the CPU features vectors between i386 and x86-64.
This also adopts the collapsing of features which are required at
compile-time into constant tests from x86-64 to i386.

f8c09377d7 include/asm-i386/boot.h: This is <asm/boot.h>, not <linux/boot.h>
include/asm-i386/boot.h incorrectly has the multiple include guards
as _LINUX_BOOT_H instead of _ASM_BOOT_H.  Fix.

48dd643c3b hd.c: remove BIOS/CMOS queries
An ST-506 disk these days is pretty much someone trying to pull ancient
data using an auxilliary controller.  Pulling data from the BIOS or CMOS
is just plain wrong, since it's likely to be the primary OS disk... and
would be user-entered data anyway.  Instead, require the user enters it
on the command line.

de61b542b8 [MIPS] Rename PC speaker code
While the PC speaker is wired up to the i8254 there is more to the i8254
than just the PC speaker so this code was getting in the way under its
current name.

fdc1f93847 [MIPS] Don't use genrtc.
The only pseudo-legitimate MIPS user of genrtc was a systems that doesn't
have an RTC in hardware at all.  At this point faking one is a little
pointless ...
