The audio controller in the H3 is more or less the same as A10/A20 except
some registers are shuffled around. The mixer interface, however, is
completely different between SoCs. Separate a10_mixer_class and
h3_mixer_class implementations are now made available. This will also make
adding support for other SoCs easier in the future.

I used this during driver bring-up to find that the Linux driver holds a
whole lot of locks whilst doing their equivalent of busdma operations.
If this works out well, it should be added to the other architecture busdma
implementations to aid in similar debugging.
Tested:
* bounce buffer and dmar busdma, Lenovo X230 laptop, all the internal
hardware
* ath(4) too

This is a long time coming. The general pieces have been floating around
in a local repo since circa 2012 when I dropped the net80211 support
into the tree.
This allows the per-chain RSSI and NF to show up in 'ifconfig wlanX list sta'.
I haven't yet implemented the EVM hookups so that'll show up; that'll come
later.
Thanks to Susie Hellings <susie@susie.id.au> who did the original work
on this a looong time ago for a company we both worked at.
Now that the changes to the dirname(3) function had some time to settle,
let's go ahead and use the same approach for replacing basename(3) by a
simple implementation that modifies the input string, thereby making it
thread-safe and guaranteed to succeed.
Unlike dirname(3), this function already had a thread-safe variant
basename_r(3). This function had its own set of problems, like having an
upper bound on the pathname length. Keep this function around for
compatibility, but remove most references from the man page. Make the
man page more similar to that of dirname(3).
As the basename_r(3) function is only provided by FreeBSD (and Bionic),
depending on its use is even more implementation defined than assuming
that basename(3) is thread-safe.

Currently lzc_receive() requires that its snapname argument is a snapshot name
(contains '@').
zfs receive allows to specify just a dataset name and would try to deduce the
snapshot name from the stream.
I propose to allow lzc_receive() to do the same.
That seems to be quite easy to implement, it requires only a small amount of
logic, it does not require any additional system calls or any additional data
from the stream.
The benefit is that the new behavior would allow to keep the snapshot names the
same between the sender and receiver at zero cost, without a need to pass the
names out of band.

If dotdot lookup does not escape from the file descriptor passed as
the lookup root, we can allow the component traversal. Track the
directories traversed, and check the result of dotdot lookup against
the recorded list of the directory vnodes.
Dotdot lookups are enabled by sysctl vfs.lookup_cap_dotdot, currently
disabled by default until more verification of the approach is done.
Disallow non-local filesystems for dotdot, since remote server might
conspire with the local process to allow it to escape the namespace.
This might be too cautious, provide the knob
vfs.lookup_cap_dotdot_nonlocal to override as well.

This behaviour broke autounmountd(8) - if you tried to manually unmount
a mounted filesystem, using 'automount -u', and the autounmountd attempted
to refresh the filesystem list in that very moment, it would conclude that
the filesystem got unmounted and not try to unmount it afterwards.

Summary:
i.MX5 and PowerPC use a very similar eSDHC controller, which is also
similar to the uSDHC controller used by i.MX6. The imx_sdhci driver works
almost completely with PowerPC, with some minor tweaks.
There is one caveat with this: reset currently does not work on PowerPC, so has
been #ifdef'd out until this can be tracked down and fixed. If resets are done
the controller will timeout all data transactions. Without a reset, it appears
to work just fine.
This is part 3, following up r308186 and r308187.
Test Plan:
This has been tested on a PowerPC QorIQ P1022 board. It has not been
tested on i.MX, but no regressions are expected.

Some controllers (namely Freescale's eSDHC, tested) will continue to assert
the card removed or card insert interrupts even after being handled. To work
around this, disable watching the interrupt that just occurred until the
opposite interrupt is triggered.
Linux has a similar change in its driver to address the same problem.
