- First three fields of system UUID may be little-endian as described in
SMBIOS Specification v2.6. For now, we keep the network byte order for
backward compatibility (and consistency with popular dmidecode tool)
if SMBIOS table revision is less than 2.6. However, little-endian format
can be forced by defining BOOT_LITTLE_ENDIAN_UUID from make.conf(5) if it
is necessary.
- Replace overly ambitious optimizations with more readable code.
- Update comments to SMBIOS Specification v2.6 and clean up style(9) bugs.
as 'real memory' instead of Maxmem if the value is available.
Note amd64 displayed physmem as 'usable memory' since machdep.c r1.640
to unconfuse users. Now it is consistent across amd64 and i386 again.
While I am here, clean up smbios.c a bit and update copyright date.

Use 'BOOT_SENSITIVE_INFO=YES' variable to turn them on.
- Use 'uint*_t' instead of 'u_int*_t', correct compilation warnings, and
update copyright while I am here.

These strings can be used to detect hardware quirks and to set appropriate
flags. For example, Compaq R3000 series and some HP laptops require
hint.atkbd.0.flags="0x9"
to boot. See amd64/67745 for more detail.
Note: Please do not abuse this feature to resolve general problem when it
can be fixed programmatically. This must be used as a last resort.
