locate a high memory area for the heap using the SMAP.
- Read the number of hard drive devices from the BIOS instead of hardcoding
a limit of 128. Some BIOSes duplicate disk devices once you get beyond
the maximum drive number.

fd_set bits in select(2). It seems that historical behaviour is to not

where running ofwdump could cause hangs by forcing all secondary CPUs
into a busy wait with interrupts off during the call.
Following section 8.4 of the Open Firmware PowerPC processor binding,
the firmware is free to overwrite the system interrupt handlers during
OF calls, restoring the OS handlers on exit. On single CPU systems, this
process is invisible to the operating system. On multiple CPU systems,
taking any exception on a secondary CPU while an OF call is in progress
ends with that exception vectored into OF, resulting in a slow movement
of the entire system into firmware context and a machine hang.

utilities and related support files for manual pages, which were previously
controlled by MAN. For POLA, the default depends on MAN, i.e., WITHOUT_MAN
implies WITHOUT_MAN_UTILS and WITH_MAN implies WITH_MAN_UTILS. This patch
is slightly improved by me from:

FILESYSTEMS (the default early_late_divider):
1. Move sysctl to run first
2. Move as many BEFOREs to REQUIREs as possible.
3. Minor effect, move hostid_save from right before mdconfig to right
after.
A lot of the early scripts make use of sysctl one way or another so
running this first makes a lot of sense given that system-critical
values are often placed in sysctl.conf.
My original purpose for working on this was that while doing some
debugging on other stuff I noticed that the order of execution was
different in the first pass through the early scripts and the second.
In practice that doesn't matter because the scripts are not executed the
second time. However this _can_ result in problems if the difference in
the rcorder moves a script from the late section to the early section in
the second pass (which would mean the script would not get executed).
So, I wanted to make the order of execution of the scripts in the early
section more deterministic.
In the course of debugging the ordering problems I noticed that moving
the BEFOREs to REQUIREs prevented the changes in order from the first
pass to the second pass without having to make any substantial changes.
(Of course it's no secret that I think BEFORE should be avoided as much
as possible, but this is a good example of why.)

socket while it is still in use.
priv->ctlsock is checked at the top of the function but without any
lock held, which means the control socket state may certainly change.
Add a similar protection to ngs_shutdown() even if a race is unlikely
to be experienced there.

loader(8)
In r193192 loader(8) has grown an ability to pass root mount options
from fstab via vfs.root.mountfrom.options. Unfortunately, some options
that can be present in fstab are for userland only and lead to root
mounting failure when seen by kernel.
Rather than teaching loader about FFS-specific options that should be
filtered out, ffs_mount recognizes those options as valid, but ignores
and deletes[1] them.
