If we parse mbuf for TSO early and use firmware-assisted TSO, we do not
expect mbuf data access when we compose firmware-assisted TSO (v1 or v2)

FATSO cannot be used because of, for example, too big header, we do not
care about a bit more performance degradation because of prefetch

This is needed for two reasons:
* Drivers will need to know what the negotiated set of VHT capabilities
and rates are in order to configure (and reconfigure for opmode/chanwidth
changes) how to speak to a given peer; and
* Because some vendors are "special", we should be careful in what we announce
to them during peer association.
This isn't the complete solution, as I still need to make sure that when
sending out probe requests before we know what we want, we don't limit
the capabilities being announced. This is important for IBSS/mesh work
later on as probe request/response exchanges are the first hint at what
a peer supports. I'll look at adding that to the API soon.

card presence and write protect switch detection.
A bridge driver just needs to call the setup routine in its attach(), the

the sdhci interface functions to the new helper functions. This is not
extensively documented, but multiple examples will exist real soon.
card insert/remove events on controllers that don't implement the insert
and remove interrupts.
Bridge drivers can set a new slot option, SDHCI_NON_REMOVABLE, to indicate
non-removable media (such as eMMC). The sdhci driver will not enable
insert/remove interrupts, and sdhci_generic_get_card_present() will always
return true.
Bridge drivers can set a new quirk, SDHCI_QUIRK_POLL_CARD_PRESENT, and the
sdhci driver will not enable insert/remove interrupts, and instead will use
a callout to poll the card-present status at 5 Hz.
For bridge drivers that get notified of card insert/remove via gpio
interrupts, there is a new sdhci_handle_card_present() function they can
call from the gpio interrupt handler to inform the sdhci code of the event.
In addition to adding these new features, the existing code to debounce card
insertions was updated to use taskqueue_enqueue_timeout() instead of
scheduling a callout to do the taskqueue_enqueue(). There is also now a
comment explaining that insertion-debounce is what's going on -- it took me
a long time to realize that's what the old sdhci_card_delay() routine was
really doing. There is no functional difference between the old and new
debounce code (I hope!).

This is a skeleton set based on ieee80211_ht.c. It implements some IE

However, by itself it's not enough to do VHT - notably, the actual
channel promotion for STA mode at least is done in ieee80211_ht.c as
part of htinfo_update_chw(). I was .. quite amused when I found that
out.
I'm checking this in so others can see progress rather than one huge
commit when VHT is "done" (which will likely be quite a while.)
Many embedded SoC controllers that are (more or less) sdhci-compatible don't
implement card detect, and the related values in the PRESENT_STATE register
aren't useful. A bridge driver can now implement get_card_present() to read
a gpio pin or whatever else is necessary for that system.
The default implementation reads the CARD_PRESENT bit from the PRESENT_STATE
register, so existing drivers will keep working (or keep not-fully-working,
since many drivers right now can't detect card insert/remove).
sched_*(2) syscalls might be not available at runtime. Defining this

* Add ioctl plumbing for enabling/disabling VHT and each of the VHT
widths.
Note: this DOES change the ABI (the driver caps ioctl struct size, sigh)
so this will require a recompile of at least ifconfig.
In preparation for VHT station support, we need to store VHT IEs when
scanning so we can choose to upgrade to VHT.
This doesn't change the ABI - it just steals spare[] entries.
The VHT operational element (VHTOPMODE) isn't a uint32_t - it's
the MCS sets, freq1/freq2 parameters and channel width.
So, store the channel width too in lieu of just storing the
IE struct.
This changes the VHT parameter layout in ieee80211_node but it
doesn't change ABI at all.
The 11n code uses these bits for both configuration /and/ controlling
the channel width on softmac chips - it uses it to find the widest
width for all VAPs (eg a HT20 vap and a HT40 vap) to know what to
configure the ic_curchan.
For fullmac devices it isn't /as/ important, as each virtual device
exposed by the firmware will likely have its own configuration and the
firmware figures out what to do to enable it.
These came from Linux mac80211 headers and are configuration bits, not
VHTOPMODE field parameters.
Whilst here, add the field names for the VHTCAP bits.

The HT40 channel population logic was "just" doing pairs of channels starting with
the band entry frequency. Trouble is, a lot of the rules start way off at 5120MHz,
which isn't a valid 5GHz channel. Then, eg for HT40U, it would populate:
* (5120,5140)
* (5160,5180)
* (5200,5220)
* (5240,5260)
.. as the HT40U pairs, with the first being the primary channel. Channel 36
is 5180MHz, and since it's not a primary channel here, it wouldn't populate it.
Then, the next HT40U would be 5200/5220, which is highly wrong.
HT40D had the same problem.
So, this just forces that 5GHz HT40 channels start at channel 36 (5180),
no matter what the band edge says. This includes eg doing 4.9GHz channels.
This erm, meant that the HT40 channels for the low band was always wrong.

Upon each execve, we allocate a KVA range for use in copying data to the
new image. Pages must be faulted into the range, and when the range is
freed, the backing pages are freed and their mappings are destroyed. This
is a lot of needless overhead, and the exec_map management becomes a
bottleneck when many CPUs are executing execve concurrently. Moreover, the
number of available ranges is fixed at 16, which is insufficient on large
systems and potentially excessive on 32-bit systems.
The new allocator reduces overhead by making exec_map allocations
persistent. When a range is freed, pages backing the range are marked clean
and made easy to reclaim. With this change, the exec_map is sized based on
the number of CPUs.

Previously, the stack unwinder tried to locate the start of the function
in each frame by walking backwards until it found an instruction that
modified the stack pointer and then assumed that was the first instruction
in a function. The unwinder would only print a function name if the
starting instruction's address was an exact match for a symbol name.
However, not all functions generated by modern compilers start off functions
with that instruction. For those functions, the unwinder would fail to
find a matching function name. As a result, most frames in a stack
trace would be printed as raw hex PC's instead of a function name.
Stop depending on this incorrect assumption and just use db_printsym()
like other platforms to display the function name and offset for each
frame. This generates a far more useful stack trace.
While here, don't print out curproc's pid at the end of the trace. The
pid was always from curproc even if tracing some other process.

However, the kernel doesn't null-terminate them. A bunch of copy-pasted code

least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually
overflows. You can see the result by doing "camcontrol negotiate da0 -v".

Instead of spuriously re-reading the lock value, read it once.
This change also has a side effect of fixing a performance bug:
on failed _mtx_obtain_lock, it was possible that re-read would find
the lock is unowned, but in this case the primitive would make a trip
through turnstile code.
This is diff reduction to a variant which uses atomic_fcmpset.
Discussed with: jhb (previous version)

It was a temporary change to ease an import of native atomic_cas primitives.
Instead, atomic_fcmpset was devised with different semantics. See r311168.

On systems without a configured swap device, an attempt to launder pages
from a swap object will always fail and result in the page being
reactivated. This means that the page daemon will continuously scan pages
that can never be evicted. With this change, anonymous pages are instead
moved to PQ_UNSWAPPABLE after a failed laundering attempt when no swap
devices are configured. PQ_UNSWAPPABLE is not scanned unless a swap device
is configured, so unreferenced unswappable pages are excluded from the page
daemon's workload.

The boot2 family of bootblocks (zfsboot/gptzfsboot) are using separate
implementation if keyboard reading code, which has deadlock case when
extended key (arrows etc) are pressed.
The problem is about avoiding the noise from some systems, generating
false key events with scan code 1 and ascii code 00, so the code
does attempt to filter such cases out. Unfortunately the extended keys
also set ascii 0, and therefore the pressed key event is ignored and
the keypress is never read, resulting in infinite loop.
This update is moving the check to keyhit() function and is allowing
the rest of the code to process the extended keys.

The previous API had various problems, including the length of the
caller provided buffer not being specified, no means being available
to discover how big the buffer needs to be, and a lack of clarity of
what the resulting list contains.
To fix it:
- add the buffer length as a parameter
- if the provided buffer is too short, fail with ENOSPC and return the
required length
- ensure that the list contents are valid and add comments
describing it
It is safe to change this API as, unsuprisingly, it has no users.

The flag EFX_FILTER_MATCH_LOC_MAC_IG to represent filtering on the
individual/group bit of the MAC address (with the two cases being
distingusished by the MAC address in the filter specification) was
introduced to mirror the Linux driver filtering code, but the
implementations are different enough anyway that it isn't of much value.
Having separate flags for unknown unicast and multicast simplifies
the code and allows the set of flags to match those used by MCDI.
It will also makes it easier to report whether these filters are
supported.
In the MCDI definitions, the unknown multicast and unicast flags have
the values 0x40000000 and 0x80000000 respectively, and so using the
same values for simplicity requires 32 bits in the filter specification
to store the flags. This means the structure is now a little bigger
than 64 bytes, but filters are not often used on critical paths so this
shouldn't have much impact - on Linux they are also bigger than they
used to be.
