This is a trivial comment-only fix. The man page for kevent(2) gives
the definition of struct kevent, including a comment on each
field. The actual definition in sys/event.h omitted the comments on
some fields. Add the comments in. Not only does this make the man page
and include file agree, but the comments are useful in and of
themselves.

Query the minimal inline mode supported by the card.
When creating a send queue, cache the queried mode and optimize the transmit
if no inlining is required. In this case, we can avoid touching the headers
cache line and avoid dirtying several more lines by copying headers into
the send WQEs. Also, if no inline headers are used, hardware assists in
the VLAN tag framing.

Track session objects in the framework, and pass handles between the
framework (OCF), consumers, and drivers. Avoid redundancy and complexity in
individual drivers by allocating session memory in the framework and
providing it to drivers in ::newsession().
Session handles are no longer integers with information encoded in various
high bits. Use of the CRYPTO_SESID2FOO() macros should be replaced with the
appropriate crypto_ses2foo() function on the opaque session handle.
Convert OCF drivers (in particular, cryptosoft, as well as myriad others) to
the opaque handle interface. Discard existing session tracking as much as
possible (quick pass). There may be additional code ripe for deletion.
Convert OCF consumers (ipsec, geom_eli, krb5, cryptodev) to handle-style
interface. The conversion is largely mechnical.
The change is documented in crypto.9.

up serial output. Setting the cursor position after every character is
inefficient, and causes all lines to be over-printed in the serial
console for the boot loader. Allow the terminal to do the emulation.
This isn't completely perfect when the size of the terminal attached
to the serial port isn't the same as 80x25 to match the viedoe console
(or whatever the video console is). While imperfect still, these
changes make it much better.
This makes the serial port useful with UEFI.

Also, I misspoke in r336428. Any devices on sparc64 machines on "isa"
that can do DMA can do 32-bit address DMA and aren't limited to
24-bits of address.
Also, fix a bug in common code that could cause other tests to fail: using
ppoll(2) in combination with buffered I/O for /dev/auditpipe. Fix it by
disabling buffering.

Plumb the %VERSREQ from Makefile.<arch> through to the rest of config(8).
We've recorded the config(8) version that we're calling "the end of
envmode and hintmode," and we'll write them out for earlier versions. Later
kernel version bumps will remove envmode/hintmode from the kernel as needed,
which is OK since the current kernel does not use them at all.
These compatibility shims really need to go away when the major version
rolls over...

Remove the STDC CX_LIMITED_RANGE pragma and its verbose comment. We still
don't have any C99 compilers (that support fenv pragmas), and if we did
then there are thousands of other places in libm that would need to use
them more than here.
The other cleanups are smaller.
For setups having a large amount of PCI devices, it makes sense to limit the
number of MSIX vectors per PCI device, in order to avoid running out of IRQ
vectors.

and csqrtl().
When one component is huge and the other is tiny, scaling down the tiny
component gave spurious underflow.
When both components are denormal, not scaling them up gave inaccuracies
of 34+ ulps on not very carefully selected args. Fixing this reduces the
maximum error to 1.6 ulps on the same set of args (mosly not denormal ones).
The scaling used multiplication of a complex variable by 2, but clang messes
this on amd64 up by losing the sign of -0.0. Calculate the components
separately, as is well known to be needed for operations on more exceptional
values.
