Explain that we set up the descriptors for Big Real Mode, and why we
do so. In particular, one system that is known to fail without it is
the Lenovo X61.
Signed-off-by: H. Peter Anvin <hpa@zytor.com>

The explanation for recent video BIOS suspend quirk failures is that
the VESA BIOS expects to be entered in Big Real Mode (*.limit = 0xffffffff)
instead of ordinary Real Mode (*.limit = 0xffff).
This patch changes the segment descriptors to Big Real Mode instead.
The segment descriptor registers (what Intel calls "segment cache") is
always active. The only thing that changes based on CR0.PE is how it is
*loaded* and the interpretation of the CS flags.
The segment descriptor registers contain of the following sub-registers:
selector (the "visible" part), base, limit and flags. In protected mode
or long mode, they are loaded from descriptors (or fs.base or gs.base can
be manipulated directly in long mode.) In real mode, the only thing
changed by a segment register load is the selector and the base, where the
base <- selector << 4. In particular, *the limit and the flags are not
changed*.
As far as the handling of the CS flags: a code segment cannot be writable
in protected mode, whereas it is "just another segment" in real mode, so
there is some kind of quirk that kicks in for this when CR0.PE <- 0. I'm
not sure if this is accomplished by actually changing the cs.flags register
or just changing the interpretation; it might be something that is
CPU-specific. In particular, the Transmeta CPUs had an explicit "CS is
writable if you're in real mode" override, so even if you had loaded CS
with an execute-only segment it'd be writable (but not readable!) on return
to real mode. I'm not at all sure if that is how other CPUs behave.

As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory. Thus a NULL test or memset after calls to these
functions is unnecessary.

If the Linux system is already running, the new reipl sysfs attribute
'parm' can be used to change kernel parameters for the next reboot.

In case the initrd is located within the bss section it will be
overwritten when the section is cleared. To prevent this just move
the initrd right behind the bss section if it starts within the
section.
The current code already moves the initrd if the bootmem allocator
bitmap would overwrite it. With this patch we should be safe against
initrd corruptions.
