byte, rather than the number of permissible bytes (i.e. subtract one
from the value under the previous definition to get the value under
the new definition).

This avoids integer overflow on 64-bit kernels, where
bzhdr.initrd_addr_max may be 0xffffffffffffffff; under the old
behaviour we set mem_limit equal to initrd_addr_max+1, which meant it
ended up as zero.  Kernel loads would fail with ENOBUFS.

confusing to read the code.

stack; it breaks vmxassist.

work around limitations in real-mode virtualisation support on Intel

Added redundant call to get_memmap() in int13_boot() immediately
before jumping to boot sector, to assist in debugging.

require that we use drive 0x80, so it should probably be the default.

Some shuffling around of the image management code; this needs tidying up.

Added FEATURE() macros to most relevant (non-driver) files.

Experimentation reveals that gcc ignores -mrtd for the implicit
arithmetic functions (e.g. __udivdi3), but not for the implicit
memcpy() and memset() functions.  Mark the implicit arithmetic
functions with __attribute__((cdecl)) to compensate for this.

(Note: we cannot mark with with __cdecl, because we define __cdecl to
incorporate regparm(0) as well.)

allow the UNDI NIC interrupt to happen.

This reverts commit 9e7b165017.

already handled the INT13 call.

Add some of the missing parts to libkir.h.

us to round down the size for the relocation copy to the nearest 64kB

last 64kB of the image is all-zeroes anyway (it's the .bss).
