    Use a new CPU feature word to cover all Intel features that 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.

    If the video BIOS is not capable of switching or failed to switch the
    hardware to 8-bit DAC, the channel properties are not set.  This leads
    to a blank (all black) display with vesafb at 8 bpp. Fix by defaulting

    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.

    x86 setup: force the assembler to generate a 2-byte jump in header
    
    The jump instruction in the header only has two bytes available, so
    it *better* be a 2-byte jump!  Unfortunately, the assembler will
    always generate a 3/5-byte jump when the target is in a different
    section.  Deal with that by generating the jump instruction
    explicitly from .byte's, just like we do elsewhere when we need a
    specific binary representation of a certain instruction.

    x86 new setup: use appropriate sections for code and data
    
    An intermediate elf file is generated for the 16-bit setup code.
    The generated code can be viewed using objdump -m i8086 -d. As it
    stands, it also tries to disassemble the bugger_off_msg, which
    results in garbage. This introduces two new sections to separate
    the code and the data part of the bootsector stub. It also moves
    some code from the .header section (a data section) to .inittext.

    special cases.

    x86 setup: Sadly, Cirrus removed extended text modes from their BIOS.
    
    In the later era of the Cirrus 54xx series, Cirrus removed extended text
    modes from their BIOS.  Neither Qemu nor Bochs implement them in the BIOS.
    If we can find a direct-register-poking method of setting them that
    works in Bochs/Qemu it might be worthwhile to resurrect this; the probing
    routine *does* work.
    
    Of course, the Right Thing[TM] would be to submit such a routine to the
    Bochs/Qemu BIOS as a VESA text mode.
