IPv4 and IPv6 to be available and ask the user to configure it
by calling
- netconfig_ipv4 doing DHCP and static IPv4 addresses, and
- netconfig_ipv6 doing rtsol and static IPv6 addresses,
and then checking, querying and updating resolv.conf upon return.
Both DHCP and rtsol (in the future) might update resolv.conf already so
we seed ourselves from that file if available.

a sync(2) syscall before unmount(2) for the "-f" case.
This avoids a forced dismount from getting stuck for
an NFS mountpoint in sync() when the server is not
responsive. With this commit, forced dismounts should
normally work for the NFS clients, but can take up to
about 1minute to complete.

When notifying the protocol that some data has been drained the
lock is released for a moment. Returning we block waiting for the
rest of data. There is a race, when data could arrive while the
lock was released and then the connection stalls in sbwait.
Fix this by checking for data before blocking and skip blocking
if there are some.

o In bare_probe(), change the logic that determines the maximum
number of processors/cores into a switch statement and take
advantage of the fact that bit 3 of the SVR value indicates
whether we're running on a security enabled version. Since we
don't care about that here, mask the bit. All -E versions
are taken care of automatically.

MPC8555(E) has 8 LAWs, so don't make that the default case. Current
processors have 12 LAWs so use that as the default instead.
o Determine the target ID of the PCI/PCI-X and PCI-E controllers in
a way that's more future proof. There's almost a perfect mapping
from HC register offset to target ID, so use that as the default.
Handle the MPC8548(E) specially, since it has a non-standard target
ID for the PCI-E controller. Don't worry about whether the processor
implements the target ID here, because we should not get called for
PCI/PCI-X or PCI-E host controllers that don't exist.
This means these features do not work as expected with multibyte characters.
This perhaps less than ideal behaviour matches printf(3) and is specified by
POSIX.
Examples:
LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244)
LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344)
Both of these should print 228.
Like some other shells, incomplete or invalid multibyte characters yield the
value of the first byte without a warning.
Note that there is no general way to go back from the character code to the
character.

from U-Boot, the kernel is passed a standard argc/argv pair.
The Juniper loader passes the metadata pointer as the second
argument and passes 0 in the first. The FreeBSD loader passes
the metadata pointer in the first argument.
As such, have locore preserve the first 2 arguments in registers
r30 & r31. Change e500_init() to accept these arguments. Don't
pass global offsets (i.e. kernel_text and _end) as arguments to
e500_init(). We can reference those directly.
Rename e500_init() to booke_init() now that we're changing the
prototype.
In booke_init(), "decode" arg1 and arg2 to obtain the metadata
pointer correctly. For the U-Boot case, clear SBSS and BSS and
bank on having a static FDT for now. This allows loading the
ELF kernel and jumping to the entry point without trampoline.

correctly during a forced dismount. This required that
the exclusive and shared (refcnt) sleep lock functions check
for MNTK_UMOUNTF before sleeping, so that they won't block
while nfscl_umount() is getting rid of the state. As
such, a "struct mount *" argument was added to the locking
functions. I believe the only remaining case where a forced
dismount can get hung in the kernel is when a thread is
already attempting to do a TCP connect to a dead server
when the krpc client structure called nr_client is NULL.
This will only happen just after a "mount -u" with options
that force a new TCP connection is done, so it shouldn't
be a problem in practice.

The "exp" builtin is undocumented, non-standard and not very useful.
If exp's return value is not used, something like
VAR=$(exp EXPRESSION)
is equivalent to
VAR=$((EXPRESSION))
except that errors in the expression are fatal and quoting special
characters is not needed in the latter case.
If exp's return value is used, something like
if exp EXPRESSION >/dev/null
can be replaced by
if [ $((EXPRESSION)) -ne 0 ]
with similar differences.
The exp-run showed that "let" is close enough to bash's and ksh's builtin
that removing it would break a few ports. Therefore, "let" remains in 9.x.
