andvar | Allocate buf[6] instead of buf[5] to work around buggy firmware, which may
write mementry to 24 bytes instead 20 requested with ACPI 3.0 enabled,
causing corrupted stack and wrong marks[] values in common_load_kernel().
This in turn was leading to erroneous caluclations and memory addresses.
This eventually may result in null pointer dereference in the kernel and sudden
reboot for VIA based systems.
Commit should fix boot issues for VIA C7-M based HP 2133 Mini-Note,
mentioned in the original bug report. For AMD based HP Compaq 6005 Pro
discussed in a separate thread, the issue may be different.
Tested on my VIA C7-D based Biostar Viotech 3100+ motherboard.

dsl | Change getextmem2 to return 'configured' values from cx/dx if ax/bx zero,
make absolutely high the top 16bits of returned values are zero.
Ralf's list says that some BIOS need %eax = 0x0000e820 in getmementry.
Add a few comments.
Might fix problems with memory size detection on some systems.

dsl | Change all .S files to use .code16 and .code32
Support 32bit addresses >64k as valid on bios calls.
Move stack for dosboot and biosboot to >64 so stack doesn't hit data.
Use disk sector number passed by mbr code to select default partition
(the mbr code doesn't do this yet).
NB only biosboot and dosboot have been tested so far.

drochner | change the interface for getmementry() to hold the iterator in an
argument and to return success or error explicitely.
Now we can "error" and "end of list" cleanly; this should fix the
problem where the last list element was ignored.

New, optional, method to get size of extended memory.
It will be used for getextmem() if EXTENDED_MEMDETECT is defined.
Worked on all tested machines.
