1. Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
there's a bootstrap complication in ths respect. Avoid it. Make the
necessary changes to have upgrade_checks work wth bmake anyway.
2. Remove the use of -E. It's not needed in our build because we use ?= for
the respective variables, which means that we'll take the environment
value (if any) anyway.
3. Properly declare phony targets as phony as bmake is a lot smarter (and
thus agressive) about build avoidance.
4. Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
smarter about build avoidance and should not find files we generate in
the source tree. We should not have files in the repository we want to
generate, but this is an easier way to cross this hurdle.
5. Have behavior under bmake the same as it is under make with respect to
halting when sub-commands fail. Add "set -e" to compound commands so
that bmake is informed when sub-commands fail.
6. Make sure crunchgen uses the same make as the rest of the build. This
is important when the make utility isn't called make (but bmake for
example).
7. While here, add support for using MAKEOBJDIR to set the object tree
location. It's the second alternative bmake looks for when determining
the actual object directory (= .OBJDIR).

the temporary mappings that are used to implement operations like
pmap_zero_page(). There is no reason for the MIPS pmap to deviate
from that practice.
This should allow to mount a dataset as a root filesystem even if
it belongs to a pool that is not described in zpool.cache.
This adds some overhead to the boot process though.
If the root filesystem's pool is found in zpool.cache, the by default
its cached configuration will be used for import.
vfs.zfs.rootpool.prefer_cached_config could be set to zero to force

To handle the one known special case of a command that accepts a 12k

to 32k rather than 16k. The result is that commands less than 8k should

The code is based on couple of files from OpenBSD, significantly

Parser differentiates for four levels of verbosity: no -v, -v,

We don't yet forward this code upstream, because currently it

this can be fixed in future.

* jail_setv will leak a parameter name if jailparam_import fails.
* jailparam_all loses the jailparam pointer on realloc error
(a clear freshman mistake).
* If jailparam_init fails, the caller doesn't need to jailparam_free

jailparam_free to work without error (though it's still not required).
AR5416 and AR9280, but leave it disabled by default.
TL;DR: don't enable this code at all unless you go through the process
of getting the NIC re-certified. This is purely to be used as a
reference and NOT a certified solution by any stretch of the imagination.
The background:
The AR5112 RF synth right up to the AR5133 RF synth (used on the AR5416,
derivative is used for the AR9130/AR9160) only implement down to 2.5MHz
channel spacing in 5GHz. Ie, the RF synth is programmed in steps of 2.5MHz
(or 5, 10, 20MHz.) So they can't represent the quarter rate channels
in the 4.9GHz PSB (which end in xxx2MHz and xxx7MHz). They support
fractional spacing in 2GHz (1MHz spacing) (or things wouldn't work,
right?)
So instead of doing this, the RF synth programming for the AR5112 and
later code will round to the nearest available frequency.
If all NICs were RF5112 or later, they'll inter-operate fine - they all
program the same. (And for reference, only the latest revision of the
RF5111 NICs do it, but the driver doesn't yet implement the programming.)
However:
* The AR5416 programming didn't at all implement the fractional synth
work around as above;
* The AR9280 programming actually programmed the accurate centre frequency
and thus wouldn't inter-operate with the legacy NICs.
So this patch:
* Implements the 4.9GHz PSB fractional synth workaround, exactly as the
RF5112 and later code does;
* Adds a very dirty workaround from me to calculate the same channel
centre "fudge" to the AR9280 code when operating on fractional frequencies
in 5GHz.
HOWEVER however:
It is disabled by default. Since the HAL didn't implement this feature,
it's highly unlikely that the AR5416 and AR928x has been tested in these
centre frequencies. There's a lot of regulatory compliance testing required
before a NIC can have this enabled - checking for centre frequency,
for drift, for synth spurs, for distortion and spectral mask compliance.
There's likely a lot of other things that need testing so please don't
treat this as an exhaustive, authoritative list. There's a perfectly good
process out there to get a NIC certified by your regulatory domain, please
go and engage someone to do that for you and pay the relevant fees.
If a company wishes to grab this work and certify existing 802.11n NICs
for work in these bands then please be my guest. The AR9280 works fine
on the correct fractional synth channels (49x2 and 49x7Mhz) so you don't
need to get certification for that. But the 500KHz offset hack may have
the above issues (spur, distortion, accuracy, etc) so you will need to
get the NIC recertified.
Please note that it's also CARD dependent. Just because the RF synth
will behave correctly doesn't at all mean that the card design will also
behave correctly. So no, I won't enable this by default if someone
verifies a specific AR5416/AR9280 NIC works. Please don't ask.
Tested:
I used the following NICs to do basic interoperability testing at
half and quarter rates. However, I only did very minimal spectrum
analyser testing (mostly "am I about to blow things up" testing;
not "certification ready" testing):
* AR5212 + AR5112 synth
* AR5413 + AR5413 synth
* AR5416 + AR5113 synth
* AR9280
