from OpenFirmware be 16 pages to avoid fragmentation in the list
of mappings returned when the kernel requests it in pmap_bootstrap.
This allows a static buffer to be used when obtaining the existing
mappings - very useful on the G5 when random physical pages can't
be grabbed because they can't be BAT-mapped.

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"

- Teach the i386 and pc98 loaders to honor multiple console requests from
their respective boot2 binaries so that the same console(s) are used in
both boot2 and the loader.
- Since the kernel doesn't support multiple consoles, whichever console is
listed first is treated as the "primary" console and is passed to the
kernel in the boot_howto flags.

syncing the icache for modules since the kernel will do it after

This fixes the trap when loading modules at boot time.

user to interrupt autoboot process at all. Currently, even when
`autoboot_delay' is set to 0, loader(8) still allows autoboot process to be
interrupted by pressing any key on the console when the loader reads kernel
and modules from the disk. In some cases (i.e. untrusted environment) such
behaviour is highly indesirable and user should not be allowed to interfere
with the autoboot process at all.

copying, rather than a page at a time. This was creating far
too many single-page mappings, and eventually OFW overflowed
some internal data structure and refused to map any more.
The new algorithm creates far less mappings and fixed a bug
where multiple mappings for the same page would be created.
'Twas known this was a problem, but only became urgent when the
install CD's mfs_root grew large enough to cause the overflow.

they would leave enough elements on the stack that if you escaped to the

after loading such a kernel, "module_path" will be set to
an insane value. Fixed example by providing an equivalent
setting. For the record, when automatically loading a
kernel (commands "boot" and "boot-conf"), the following is
tried, in this order:
path=/boot/${kernel} file=${bootfile}
path=/boot/${kernel} file=${kernel}
path=${kernel} file=${bootfile}
path=${kernel} file=${kernel}
path=${module_path} file=${kernel}
