bec9534d1d sys/cam: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

e57b2b1830 rw: fix runlock_hard when new readers show up
When waiters/writer spinner flags are set no new readers can show up unless
they already have a different rw rock read locked. The change in r326195 failed
to take that into account - in presence of new readers it would spin until
they all drain, which would be lead to trouble if e.g. they go off cpu and
can get scheduled because of this thread.

665c8a2ee5 Add to ipfw support for sending an SCTP packet containing an ABORT chunk.
This is similar to the TCP case. where a TCP RST segment can be sent.

There is one limitation: When sending an ABORT in response to an incoming
packet, it should be tested if there is no ABORT chunk in the received
packet. Currently, it is only checked if the first chunk is an ABORT
chunk to avoid parsing the whole packet, which could result in a DOS attack.

Thanks to Timo Voelker for helping me to test this patch.

2b6a8dd52c Add a Saved Process Status Register bit for AArch32 execution mode.
The documentation on the Saved Process Status Register (SPSR) is a bit
weird; the M[4] bit is documented separately from M[3:0]. The M[4] bit
can be toggled to switch to 32-bit execution mode. This functionality is
orthogonal to M[3:0].

Change the definition of PSR_M_MASK to no longer include M[4]. Add a new
definition, PSR_AARCH32 that can be used to toggle 32-bit independently.
This bit will be used by the cloudabi32 code to force execution of
userspace code in 32-bit mode.

For FreeBSD/arm64's cloudabi32 support, I'm going to need a TO_PTR() in

difference remains as minimal as possible.

7af24ff710 Make 32-bit system calls end up in svc_handler().
The nice thing about ARM64 is that it's pretty elegant to install
separate trap/exception handlers for 32-bit and 64-bit processes. That
said, for all other architectures (e.g., i386 on amd64) we always let
32-bit counterparts go through the regular system call codepath. Let's
do the same on ARM64.

47f69f4f2b Use the cookie now set by loader to determine whether the value passed to
PowerPC kernels in r6 is actually metadata from loader(8) or gibberish
left in r6, which is not required to be anything under the
PAPR/ePAPR/CHRP/OF standards, by another boot loader.

Note that, as a result, systems need a new boot loader to boot PPC kernels
after this revision without ending up at a mountroot prompt. New boot
loaders are backwards compatible and can boot older kernels.
