Silence a coverity warning about ignoring a return value. We do, but
we also know that it "can't fail" given the single-threaded nature of
device enumeration. Go ahead and check it just in case, but add a
comment.
Reduce confusion in scalbnl() family of functions.
The changes unrelated to the bug in r277948 made
the code very difficult to understand to both
coverity and regular humans so take a step back
to something that is much easier to understand
for both and follows better the original code.
If the vm_page_alloc_contig() failed in the ttm page allocators, do
what other callers of vm_page_alloc_contig() do, retry after
vm_pageout_grow_cache().
Fix use after free in pipe_dtor(). PIPE_NAMED flag must be tested
before pipeclose() is called, since for !PIPE_NAMED case, when peer is
already closed, the pipe pair memory is freed.

Avoid hard-coding a path to ksh in scripts that are executed directly by
the test harness. This is a problem in many of the *.ksh test scripts as
well, but those scripts are executed using a shell whose path is specified
in dtest.pl, so there's no need to modify them.

Continue to handle the case where state is NULL, though this currently
cannot happen on FreeBSD. r278136 overlooked the fact that a destructor
registered with devfs_set_cdevpriv(9) is invoked even in the case of an
error.

Overhaul the relnotes page to reorganize the sections.
With the previous layout, the majority of the release
notes were categorized under one main "What's New"
section, which in addition to making the page difficult
to parse relevant bits, also had a few rendering issues,
such as 'Note' blocks visually not appearing as if they
pertain to a particular change.
This change removes the "What's New" section, integrating
it with the introduction. In addition, each section now
provides a brief description of its contents, broken down
further into a subsection for each "topic", making it much
easier to find a specific topic in the page.

Let the standard deviation of the empty set be 0. This is consistent with
the behaviour for averages, and fixes a crash that can occur when attempting
to print a stddev aggregation containing no elements:
The flowid and hashtype should be copied from the originating packet
when fragmenting IP packets to preserve the order of the packets in a
stream. Else the resulting fragments can be sent out of order when the
hardware supports multiple transmit rings.
Reorganize the list of addresses associated with an interface and group them
based on the address family. This should help to recognize interfaces with
multiple AF (e.g. ipv4 and ipv6) with many aliases or additional addresses. The
order of addresses inside a single group is strictly preserved.
Improve the scope_id output for AF_INET6 families, as the
current approach uses hexadecimal string that is basically the ID of an
interface, whilst this information is already depicted by getnameinfo(3) call.
Therefore, now ifconfig just prints the scope of address as it is defined in
2.4 of RFC 2373.
Optimise allocation of USB DMA structures. By default don't double map
allocations if only one element should be allocated per page
cache. Make one allocation per element compile time configurable. Fix
a comment while at it.
Section 3.2.9 in the XHCI specification about control transfers says
that we should use a normal-TRB if there are more TRBs extending the
data-stage TRB. Add a dedicated state bit to the internal USB transfer
flags to handle this case.

CTL LUN mapping rewrite.
Replace iSCSI-specific LUN mapping mechanism with new one, working for any
ports. By default all ports are created without LUN mapping, exposing all
CTL LUNs as before. But, if needed, LUN mapping can be manually set on
per-port basis via ctladm. For its iSCSI ports ctld does it via ioctl(2).
The next step will be to teach ctld to work with FibreChannel ports also.
Respecting additional flexibility of the new mechanism, ctl.conf now allows
alternative syntax for LUN definition. LUNs can now be defined in global
context, and then referenced from targets by unique name, as needed. It
allows same LUN to be exposed several times via multiple targets.
While there, increase limit for LUNs per target in ctld from 256 to 1024.
Some initiators do not support LUNs above 255, but that is not our problem.

Add a quirk to limit AHCI MSI vectors to one
In 10.1-RELEASE the default number of MSI vectors used was changed from one
to as many vectors as the HW supports.
This change resulted in an ahci timeouts regression when running on AMD
SB7x0/SB8x0/SB9x0 hardware, so its now limited to 1 MSI by default using
this new quirk.

Do not skip setting the memory 'reg' property if the fdt data already
contains one. Published dts source often includes a minimal default
memory definition and expects it to be overridden by the bootloader after
determining the actual physical memory in the system.

FreeBSD expects _Unwind_GetGR, _Unwind_SetGR, and _Unwind_SetIP to be
symbols and not macros. Make this so. This fixes a few ports that try to
link against these functions but fail as they previously didn't exist.

Revert r256642, not only to reduce diffs against upstream libcxxrt, but
also because it is the wrong approach: comparing typeinfo names deeply
causes trouble if two loaded DSOs use independent types of the same
name.
In addition, this particular change was never merged to FreeBSD 10.x and
9.x, so let's get rid of it before it ends up in an 11.x release.
