Use DRIVER_MODULE_ORDERED(SI_ORDER_ANY) so that ig4's ACPI attachment
happens after iicbus and acpi_iicbus drivers are registered.
I have seen a problem where iicbus attached under ig4 instead of
acpi_iicbus when ig4.ko was loaded with kldload. I believe that that
happened because ig4 driver was a first driver to register, it attached
and created an iicbus child. Then iicbus driver was registered and,
since it was the only driver that could attach to the iicbus child
device, it did exactly that. After that acpi_iicbus driver was
registered. It would be able to attach to the iicbus device, but it was
already attached, so nothing happened.

If the index we're trying to convert is 0 we can avoid a potentially

we can handle this as an error: set the errno to ENXIO and return NULL.

Preload OpenSSL ERR string data so that the formatted error messages are
vaguely meaningful. Add OpenSSL error information to the RSA_public_encrypt()
operation failure case in one-time key generation.
For obsolescent OpenSSL versions (*cough* FIPS *cough*), pre-seed the PRNG
before entering Cap mode, as old versions of OpenSSL are unaware of kernel
RNG interfaces aside from /dev/random (such as the long-supported kern.arnd, or
the slightly more recent getentropy(3) or getrandom(2)). (RSA_public_encrypt()
wants a seeded PRNG to randomize the "PS" portion of PKCS 1.5 padding or the
"MGF" pseudo-random function in OAEP padding.)
Switch dumpon to encrypt the one-time key with OAEP padding (recommended since
1998; RFC2437) rather than the obsolescent PKCS 1.5 padding (1993; RFC2313).
Switch decryptcore to attempt OAEP decryption first, and try PKCS 1.5
decryption on failure. This is intended only for transition convenience, and
we should obsolete support for non-OAEP padding in a release or two.

In r360131, acpi_ec probe was changed to not clobber an error status prior to
several error cases that did not explicitly set the error variable before
goto'ing the exit path. However, I did not notice that the error variable was
not set to success in the success path. That caused all successful probes to
fail, which is obviously undesirable.

One of the goals of the new routing KPI defined in r359823 is to entirely
hide`struct rtentry` from the consumers. It will allow to improve routing
subsystem internals and deliver more features much faster.
This commit is mostly mechanical change to eliminate direct struct rtentry
field accesses.
The only notable difference is AF_LINK gateway encoding.
AF_LINK gw is used in routing stack for operations with interface routes
and host loopback routes.
In the former case it indicates _some_ non-NULL gateway, as the interface
is the same as in rt_ifp in kernel and rtm_ifindex in rtsock reporting.
In the latter case the interface index inside gateway was used by the IPv6
datapath to verify address scope for link-local interfaces.
Kernel uses struct sockaddr_dl for this type of gateway. This structure
allows for specifying rich interface data, such as mac address and interface
name. However, this results in relatively large structure size - 52 bytes.
Routing stack fils in only 2 fields - sdl_index and sdl_type, which reside
in the first 8 bytes of the structure.
In the new KPI, struct nhop_object tries to be cache-efficient, hence
embodies gateway address inside the structure. In the AF_LINK case it
stores stortened version of the structure - struct sockaddr_dl_short,
which occupies 16 bytes. After D24340 changes, the data inside AF_LINK
gateway will not be used in the kernel at all, leaving rtsock as the only
potential concern.
The difference in rtsock reporting:

10.0.0.0 link#5 255.255.255.0
Note 40 bytes different (52-16 + alignment).
However, gateway is still a valid AF_LINK gateway with proper data filled in.
It is worth noting that these particular messages (interface routes) are mostly
ignored by routing daemons:
* bird/quagga/frr uses RTM_NEWADDR and ignores prefix route addition messages.
* quagga/frr ignores routes without gateway
More detailed overview on how rtsock messages are used by the
routing daemons to reconstruct the kernel view, can be found in D22974.

r360139 made compiling with NO_HISTORY work. This #define does not remove
the fc and bind builtins completely but makes them always write an error

However, there was also some code in builtins.def and mkbuiltins to remove

system complication to make this work seems not worth it, so remove that
code.

RFC5661 specifies that a client's recovery upon receipt of NFSERR_BADSESSION
should first consist of a CreateSession operation using the extant ClientID.
If that fails, then a full recovery beginning with the ExchangeID operation
is to be done.
Without this patch, the FreeBSD client did not attempt the CreateSession
operation with the extant ClientID and went directly to a full recovery
beginning with ExchangeID. I have had this patch several years, but since
no extant NFSv4.n server required the CreateSession with extant ClientID,
I have never committed it.
I an committing it now, since I suspect some future NFSv4.n server will
require this and it should not negatively impact recovery for extant NFSv4.n
servers, since they should all return NFSERR_STATECLIENTID for this first
CreateSession.
The patched client has been tested for recovery against both the FreeBSD
and Linux NFSv4.n servers and no problems have been observed.

In the below-referenced PR, a case is attached of a simple reproducer that
exhibits suboptimal behavior: EVFILT_READ and EVFILT_WRITE being set in the
same kevent(2) call will only honor the first one. This is, in-fact, how
it's supposed to work.
A read of the manpage leads me to believe we could be more clear about this;
right now there's a logical leap to make in the relevant statement: "When
passed as input, it forces EV_ERROR to always be returned." -- the logical
leap being that this indicates the caller should have allocated space for
the change to be returned with EV_ERROR indicated in the events, or
subsequent filters will get dropped on the floor.
Another possible workaround that accomplishes similar effect without needing
space for all events is just setting EV_RECEIPT on the final change being
passed in; if any errored before it, the kqueue would not be drained. If we
made it to the final change with EV_RECEIPT set, then we would return that
one with EV_ERROR and still not drain the kqueue. This would seem to not be
all that advisable.
