c842df4889 killall(1): Clarify -d, -s and -v options
-d and -v are not equivalent options. The former is more verbose than the
latter and the former does not actually send the signals while the latter does.
Let them have their own paragraphs.

From the point of view of the output, -v is equivalent to -s, so describe them
close to each other. The difference is that former actually sends the signals
and the latter doesn't.

b5e7ee4718 [ath_hal] Add KeyMiss for AR5212/AR5416 series chips.
This is a flag from the MAC that says the received packet didn't match
a keycache slot.  This isn't technically a problem as WEP keys don't
match keycache slots (they're "global" keys), but it could be useful
for tracking down CCMP decryption failures.

Right now it's a no-op - it mirrors what the AR9300 HAL does and it
just increments a counter.  But, hey, maybe one day I'll use it for
diagnosing keycache/CCMP decrypt issues.

f045cfb816 Chroot actually appeared in 7th Edition Unix.
Chroot appeared during the development of 7th edition Unix. The FreeBSD jail
documents, incorrectly, that Bill Joy added this to 4.2BSD on 18 March
1982. That was when Bill Joy converted from a statically coded system call glue
to dynamically generated assembler. Chroot was present in 32V, 3BSD, 4.0BSD, 4.1BSD
and 4.1cBSD well in advance of this. Kirk McKusick agrees with this analysis.

	4.1cBSD: https://minnie.tuhs.org/cgi-bin/utree.pl?file=4.1cBSD/usr/src/libc/sys/chroot.s

The 6th and earlier editions do not have this system call, nor do they have
anything named chroot in the trees available from TUHS.

4cee4598e7 Add mostly dummy hw.pci.enable_aspm tunable.
The only thing this tunable enables now is reporting to ACPI _OSC that
Active State Power Management and Clock Power Management Capability are
"supported" by the OS.

I've found that at least some Supermicro server boards do not allow OS
to support native PCIe hot-plug unless it reports those capabilities.
After spending significant time in PCIe specs I have found very little
motivation for that, and none of it applies to those motherboards, not
enabling ASPM themselves.  So unless OS explicitly wants to save power,
I see nothing for it to do there actually.

I guess it may get sense to support ASPM when we get Thunderbolt support.
Otherwise I have no system with PCIe hot-plug where power saving matters.

It would be nice to enable this by default, but I worry that it affect
power saving of some laptops, even though I haven't noticed that myself.

1264cc08ff Add MATCH option for CONFIG_MATCH_IFACE.
If the interfaces on which wpa_supplicant is to run are not known or do
not exist, wpa_supplicant can match an interface when it arrives. Each
matched interface is separated with -M argument and the -i argument now
allows for pattern matching.

As an example, the following command would start wpa_supplicant for a
specific wired interface called lan0, any interface starting with wlan
and lastly any other interface. Each match has its own configuration
file, and for the wired interface a specific driver has also been given.

wpa_supplicant \
	-M -c wpa_wired.conf -ilan0 -D wired \
	-M -c wpa1.conf -iwlan* \

4302208388 sound/hda: fix interrupt handler endless loop after r362294
Not all interrupt sources that affect CIS bit were acknowledged.
Specifically, bits in STATESTS (aka WAKESTS) were left set.

The fix is to disable WAKEEN and clear STATESTS bits before the HDA
interrupt is enabled.  This way we should never get any STATESTS bits.

I also added placeholders for all event bits that we currently do not
enable, do not handle and do not clear.  This might get useful when / if
we enable any of them.

71ab6f9708 Prevent calling USB backends multiple times.
The TRB processing loop could potentially call a back-end twice
with the same status transaction. While this was generally benign,
some code paths in the tablet backend weren't set up to handle
this case, resulting in a NULL dereference.

Fix by
 - returning a STALL error when an invalid request was seen in the backend
 - skipping a call to the backend if the number of packets in a status
   transaction was zero (this code fragment was taken from the Intel ACRN
   xhci backend)

8d8b292321 Don't log normal login_getpwclass(3) result.
The logging was introduced in r314527 but doesn't appear to be useful
for regular operation, and as the result, for users with no class set
(very common) the administrator would see a message like this in their
auth.log:

  sshd[44251]: user root login class [preauth]

(note that the class was "" because that's what's typically configured
for most users; we would get 'default' if lc->lc_class is chosen)

Remove this log as it can be annoying as the lookup happen before
authentication and repeats, and our code is not acting upon lc_class
or pw_class directly anyways.

4476c1def0 Add a boolean argument to nfscl_reqstart() to indicate that ext_pgs mbufs
should be used.

For KERN_TLS (and possibly some other future network interface) the mbuf
list passed into sosend() must be ext_pgs mbufs. The krpc could simply
copy all the mbuf data into ext_pgs mbufs before calling sosend(), but
that would be inefficient for large RPC messages.
This patch adds an argument to nfscl_reqstart() to indicate that it should
fill the RPC message into ext_pgs mbufs.
It also adds fields to "struct nfsrv_descript" needed for building NFS RPC
messages in ext_pgs mbufs, along with new flags for this.

Since the argument is always "false", this commit should not result in any
semantic change. However, this commit prepares the code
for future commits that will add support for building of NFS RPC messages
in ext_pgs mbufs.

94578db218 Reduce contention on per-adapter lock.
- Move temporary sglists into the session structure and protect them
  with a per-session lock instead of a per-adapter lock.

- Retire an unused session field, and move a debugging field under
  INVARIANTS to avoid using the session lock for completion handling
  when INVARIANTS isn't enabled.

- Use counter_u64 for per-adapter statistics.

Note that this helps for cases where multiple sessions are used
(e.g. multiple IPsec SAs or multiple KTLS connections).  It does not
help for workloads that use a single session (e.g. a single GELI
volume).

f4134e3d87 Implement an approximation of Linux MADV_DONTNEED semantics.
Linux MADV_DONTNEED is not advisory: it has side effects for anonymous
memory, and some system software depends on that.  In particular,
MADV_DONTNEED causes anonymous pages to be discarded.  If the mapping is
a private mapping of a named object then subsequent faults are to
repopulate the range from that object, otherwise pages will be
zero-filled.  For mappings of non-anonymous objects, Linux MADV_DONTNEED
can be implemented in the same way as our MADV_DONTNEED.

This implementation differs from Linux semantics in its handling of
private mappings, inherited through fork(), of non-anonymous objects.
After applying MADV_DONTNEED, subsequent faults will repopulate the
mapping from the parent object rather than the root of the shadow chain.
