Add a kernel interface (OF_xref_phandle()) for systems where phandles
used as cross-references in the device tree and phandles as used by the
Open Firmware client interface are in different namespaces. This include
IBM pSeries hardware as well as FDT systems. FDT certainly abuses
ihandles for this purpose and should be modified to use this API
eventually. This changes no behavior on systems where FreeBSD already
worked.

Properly remove c++filt.
The c++filt binary is only installed if ${MK_GCC} == yes && ${MK_CXX} ==
yes. This means that it should be removed if ${MK_GCC} == no ||
${MK_CXX} == no. In its current form, it actually uses a conjunction
instead of a disjunction.
As there is already a separate block for ${MK_CXX} == no listing
c++filt, simply remove the conditional entirely.
drm/radeon: Fix usage of pci_save_state() and pci_restore_state()
Calling those functions with the drmn device as argument causes a panic,
because it's not a direct child of pci$N. They must be called with the
vgapci device instead.
This fix is not enough to make suspend/resume work reliably.
vga_pci_(un)map_bios() takes a vgapci device as argument, not a drmn
one. This fixes a bug where the BIOS couldn't be mapped if the device
wasn't the boot display.

If the last page of the file is partially full and whole valid
portion is invalidated, invalidate the whole page. Otherwise,
partially valid page appears on a page queue, which is wrong. This
could only happen for the last page, because only then buffer which
triggered invalidation could not cover the whole page.

Reduce the scope of the proctree_lock. If several processes cause
continuous calls to the uprintf(9), the proctree_lock could be
shared-locked for indefinite amount of time, starving exclusive

effectively stops the machine.
While there, do the similar reduction for tprintf(9).

Fix an issue that caused Integrated RAID volumes on LSI mps(4) controllers
to not get scanned on boot.
The problem originated in change 253549. With the change to the mps(4)
driver to scan only targets that it knows it has (as opposed to scanning
the entire bus), scanning RAID volumes on boot was omitted.
So, for versions of FreeBSD that have the scanning changes
(__FreeBSD_version 1000039 and higher), scan RAID volumes that are added
whether or not we're booting.

After r255321, clang uses libc++ by default. This leads to a lot of
errors when you enable WITH_GNUCXX to build libstdc++, since it will
include C++ headers from the libc++ installation under ${WORLDTMP}, and
those are not compatible with libstdc++ at all.
To fix this, add -stdlib=libstdc++ to CXXFLAGS when building libstdc++
(and its companion libsupc++) with clang.

Prior to r254304, we only began scanning the active page queue when the
amount of free memory was close to the point at which we would begin
reclaiming pages. Now, we continuously scan the active page queue,
regardless of the amount of free memory. Consequently, we are continuously
calling pmap_ts_referenced() on active pages.
Prior to this change, pmap_ts_referenced() would always demote superpage
mappings in order to obtain finer-grained reference information. This made
sense because we were coming under memory pressure and would soon have to
begin reclaiming pages. Now, however, with continuous scanning of the
active page queue, these demotions are taking a toll on performance. To
address this problem, I have replaced the demotion with a heuristic for
periodically clearing the reference flag on superpage mappings.

Change the default value of VerifyHostKeyDNS to "yes" if compiled with

Clean up the OpenSSH build. It is now possible to build most components
as static binaries, if desired. The one exception is sshd, which runs
into trouble due to libpam.a's includion of pam_ssh.
Make OpenSSH use LDNS if available. This allows it to verify signed
SSHFP records.
There are two different versions of the ARM ABI depending on the
TARGET_ARCH. As these are sligntly different a package built for
one may not work on another. We need to detect which one we are on
by parsing the .ARM.attributes section.
This will only work on the ARM EABI as this section is part of the
ABI definition. As armv6 only supports the ARM EABI this is not a
problem for the oabi.
Older versions of libelf in FreeBSD fail to read the
.ARM.attributes section needed. As armv6 is unsupported on these
versions we can assume we are running on arm.
