skip past an empty region, otherwise we end up generating an infinitely
long e820 map.  (Yes, there *are* real systems that provide e820 maps
with a zero-length region at the end...)

even when we returned failure).

our manual ".code32" will break a KEEP_IT_REAL build.

Fix bug that caused over-allocation of .text16 and .data16 memory areas
by a factor of 16.

Updated PXE API dispatcher to use copy_{to,from}_user, and moved to
arch/i386 since the implementation is quite architecture-dependent.
(The individual PXE API calls can be largely
architecture-independent.)

--nulltrap to the make target at the moment.)

as a result of our memory map editing, so strip out any empty regions.

Allow our functions to return a non-zero, non-error status (since the
INT 13 Extensions Check has to return the API version in the register
that is otherwise always used for the error code).

Report a non-zero API version from the INT 13 Extensions Check; GRUB
now uses extended reads.

flow of control through this code.

We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.

UNDI loader is still missing.

on the stack.

worrying about its stack being destroyed during the Etherboot run.

install() now calls relocate(), moves the protected-mode code to the new
location, and calls hide_etherboot().

Change semantics; relocate() now just finds a suitable location; it
doesn't actually perform the relocation itself.  Code in libprefix does
the copy in flat real mode.

order?

requiring each caller to decide how many entries it wants to permit.

REAL_CODE() don't need it.

int13_boot() now does its own segment register save and restore, ready
for the removal of segment register restoration from the libkir
generic code.
