This patch lets the early real mode code look for the 'quiet' option
on the kernel command line and pass a loadflag to the decompressor.
When this flag is set, we suppress the "Decompressing Linux... Parsing
ELF... done." messages.

If we use the bootloader-provided stack pointer, we might end up in a
situation where the bootloader (incorrectly) pointed the stack in the
middle of our heap. Catch this by simply comparing the computed heap
end value to the stack pointer minus the defined stack size.

Push video mode setup as late as possible; messages issued through the
BIOS interface after video mode setup will either not be seen (for
framebuffer modes) or will screw up the cursor (for text modes.)
In particular, this makes the EDD probing message show up correctly.

Make <asm/setup.h> usable by the boot code.
Clean up vestiges of the old command-line protocol from setup.h and
head_32.S (it is still supported from the boot loader point of
view, since it is converted to the new command-line protocol by the
boot code.)
