services or PAL procedures. The new implementation is based on
specific functions that are known to be called in certain scenarios
only. This in particular fixes the PAL call to obtain information
about translation registers. In general, the new implementation does
not bank on virtual addresses being direct-mapped and will work when
the kernel uses PBVM.
When new scenarios need to be supported, new functions are added if
the existing functions cannot be changed to handle the new scenario.
If a single generic implementation is possible, it will become clear
in due time.
While here, change bootinfo to a pointer type in anticipation of
future development.
our info about worker processes if any of them was terminated in the meantime.
This fixes the problem with 'hastctl status' running from a hook called on
split-brain:
1. Secondary calls a hooks and terminates.
2. Hook asks for resource status via 'hastctl status'.
3. The main hastd handles the status request by sending it to the secondary
worker who is already dead, but because signals weren't checked yet he
doesn't know that and we get EPIPE.

the topology mutex in the following functions, that manipulate pointers
to peer nodes:
- ng_bypass()
- ng_path2noderef() when switching to the next node in sequence.
Rewrite the function a bit.
- ng_address_hook()
- ng_address_path()
This patch improves stability of large mpd5 installations.
* Pull out the static rix stuff into a different function
* I know this may slightly drop performance, but check if a static
rix is needed before each packet TX.
* Whilst I'm at it, add a little extra debugging to the rate
control stuff to make it easier to follow what's going on.
This way we know how to connect to secondary node when we are primary.
The same variable is used by the secondary node - it only accepts
connections from the address stored in 'remote' variable.
In cluster configurations it is common that each node has its individual
IP address and there is one addtional shared IP address which is assigned
to primary node. It seems it is possible that if the shared IP address is
from the same network as the individual IP address it might be choosen by
the kernel as a source address for connection with the secondary node.
Such connection will be rejected by secondary, as it doesn't come from
primary node individual IP.
Add 'source' variable that allows to specify source IP address we want to
bind to before connecting to the secondary node.

1. The PBVM is in region 4, so if we want to make use of it, we
need region 4 freed up.
2. Region 4 and above cannot be represented by an off_t by virtue
of that type being signed. This is problematic for truss(1),
ktrace(1) and other such programs.
POSIX does not require the shell to fork for a subshell environment, and we
use that possibility in various ways (command substitutions with a single
command and most subshells that are the final command of a shell process).
Therefore do not tie subshells to forking in the man page.
Command substitutions with expansions are a bit strange, causing a fork for
$(...$(($x))...) because $x might expand to y=2; they will probably be
changed later but this is how they work now.
Give it a good go (32 attempts) and then print out a warning that's
going to occur whether HAL debugging is enabled or not. Then don't
abort the radio setup; just continue merrily along.
This should fix the issue that users were having where scanning would
occasionally fail on the active channel, causing traffic to cease
until the radio scanned again.

"wired". They remain in the paging queues. However, they are pinned in
memory using vm_page_hold().
not needed.
These calibrations are only applicable if the chip operating mode
engages both interleaved RX ADCs (ie, it's compensating for the
differences in DC gain and DC offset -between- the two ADCs.)
Otherwise the chip reads values of 0x0 for the secondary ADC
(as I guess it's not enabled here) and thus writes potentially
bogus info into the chip.
I've tested this on the AR9160 and AR9280; both behave themselves
in 11g mode with these calibrations disabled.
for fixing them based on the ath9k related TXQ fixes.
I've done this so people can go over the history of the diffs to the original
AR5212 routines (which AR5416 and later chips use) to see what's changed.

- A closer inspection of the OpenSolaris code indicates the block store
workaround is only necessary in case of BUS_DMASYNC_POSTREAD.
- Mark some unused parameters as such.
In some cases as udp6_connect() without an earlier bind(2) to an
address, v4-mapped scokets allowed and a non mapped destination
address, we can end up here with both v4 and v6 indicated:
inp_vflag = (INP_IPV4|INP_IPV6|INP_IPV6PROTO)
In that case however laddrp is NULL as the IPv6 path does not
pass in a copy currently.
