This changes the build OBJDIR from the older style of /usr/obj/<srcdir> for
native builds, and /usr/obj/<target>.<target_arch>/<srcdir> for cross builds to
a new simpler format of /usr/obj/<srcdir>/<target>.<target_arch>. This
new format is used regardless of cross or native build. It allows
easier management of multiple source tree object directories.
The UNIFIED_OBJDIR option will be removed and its feature made permanent
for the 12.0 release.
Relnotes: yes (don't note UNIFIED_OBJDIR option since it will be removed)

Try to not expose bluetooth devices to external devices unless the user
explicitly configures it, like any other radio/network device. Bluetooth
has a long history of security problems and it is probably best to keep it
disabled if not needed.
Users who do use the bluetooth device should enable "discoverable" in
bluetooth.device.conf(5) after this change.
Keep in mind that bluetooth addresses can be discovered by passive
monitoring or whole address-space scans[0], so a safety conscious user
should also disable "connectable" in bluetooth.device.conf(5).

In reclaim_pv_chunk(), rotate the pv chunks list so that next
invocations of the reclaim do not scan the same pv chunks that could
not be freed. Only do the rotation when there is no parallel scan,
tracked by active_reclaims counter.
To rotate, move all chunks that are before current iteration marker,
after another marker that is inserted at the list tail on start of the
reclaim.

The VNET_SYSUNINIT() callback is executed after the MOD_UNLOAD. That means
that netisr_unregister() has already been called when
netisr_unregister_vnet() gets calls, leading to an assertion failure.
Restore the expected order of operations by performing everything that
was done in MOD_UNLOAD to a SYSUNINIT() (that will be called after the

The r195005 unlocked pmc_sx before calling into pmclog_configure_log()
to avoid the LOR, but it allows flush or closelog to run in parallel
with the configuration, causing many failure modes.
Revert r195005. Pre-create the logging process, allowing it to run
after the set up succeeded, otherwise the process terminates itself.

hwpmc(4) must not voluntarily call fo_close(), doing this causes
double-close of the file. It seems to almost avoid bad consequences
for pipes, but other types of files demonstrate random memory access.
To fix, remove fo_close() calls, which also do not provide the
declared wake-up of waiters consistently. Instead, send a signal to
the logger and configure the logger process to not block it. Since
logger never returns to userspace, the signal only causes termination
of the interruptible sleeps in fo_write().

This geom does not immediately detach its consumer relying on the
wither-washer to do that. Since that happens asynchronously we may get
additional spoiling events. So, we need to account for that.
There are multiple options for fixing this issue like detaching
immediately or checking for G_CF_ORPHAN in g_slice_spoiled().
The most reliable and least intrusive fix seems to be setting
geom->softc to NULL on the first call and checking for NULL on
subsequent calls. This is something that the code did before r325227.

This is the extra key on 102/105-keys keyboards, located on the right
of the Left Shift key. For instance on a French layout, this is the '<'
key.
This fixes an issue where the key fires no evdev event and thus remains
inactive in an evdev/libinput-enabled X.Org server. The issue only
occurred on an AT keyboard; the same key on a USB keyboard worked fine.

It is used on each new entry addition to decide whether to whack an existing
negative entry in order to prevent a blow out in size, but the parameter was
set years ago and never revisited.
Building with poudriere results in about 400 evictions per second which
unnecessarily grab entries from the hot list.
With the new parameter there are next to no evictions of the sort.
This brings it closer to par with GENERIC64. In the future I hope to have a
GENERIC64-E and GENERIC-E kernels as Book-E analogues to the GENERIC64/GENERIC
AIM kernels.
This is needed for the HDA emulation with FreeBSD guests.
