With "cached read" HDD testing and multiple ports busy on a SATA
host controller, 3726/3826 PMP will very rarely drop a deferred
R_OK that was intended for the host. Symptom will be all 5 drives
under test will timeout, get reset, and recover.

null_hashget() obtains the reference on the nullfs vnode, which must
be dropped.
- Fix a wart which existed from the introduction of the nullfs
caching, do not unlock lower vnode in the nullfs_reclaim_lowervp().
It should be innocent, but now it is also formally safe. Inform the
nullfs_reclaim() about this using the NULLV_NOUNLOCK flag set on
nullfs inode.
- Add a callback to the upper filesystems for the lower vnode
unlinking. When inactivating a nullfs vnode, check if the lower
vnode was unlinked, indicated by nullfs flag NULLV_DROP or VV_NOSYNC
on the lower vnode, and reclaim upper vnode if so. This allows
nullfs to purge cached vnodes for the unlinked lower vnode, avoiding
excessive caching.

a non-loss reset.
When the drain functions are called, the holding descriptor and link pointers
are NULLed out.
But when the processq function is called during a non-loss reset, this
doesn't occur. So the next time a DMA occurs, it's chained to a descriptor
that no longer exists and the hardware gets angry.
Tested:
* AR5416, STA mode; use sysctl dev.ath.X.forcebstuck=1 to force a non-loss
reset.
TODO:
* Further AR9380 testing just to check that the behaviour for the EDMA
chips is sane.

before using said node.
The "blessed" way here is to take a node reference before referencing
anything inside the node, otherwise the node can be freed between
the time the pointer is copied/dereferenced and the time the node contents
are used.
This mirrors fixes that I've done elsewhere in the net80211/driver
stack.

match changes that GE publishes to the Octeon Simple Executive. Since
board types overlap with other boards, it is unlikely that we will
properly boot on other Octeon boards with OCTEON_VENDOR_GEFES enabled.
Tested extensively on the WANIC 6354, but I retained support for all
the other models. Some features need changes in the base kernel, and
those are in progress.
An array-type stat in vmm.ko is defined as follows:
VMM_STAT_ARRAY(IPIS_SENT, VM_MAXCPU, "ipis sent to vcpu");
It is incremented as follows:
vmm_stat_array_incr(vm, vcpuid, IPIS_SENT, array_index, 1);
And output of 'bhyvectl --get-stats' looks like:

assigned conflicting ranges to BARs then leaving the BARs alone could
result in one device stealing mmio accesses intended to go to a second
device. Prior to 233677 the PCI bus driver attempted to handle this case
by clearing the BAR to 0 depending on BARs based at 0 not decoding (which
is not guaranteed to be true). Now when a conflicting BAR is detected the
following steps are taken:
1) If hw.pci.realloc_bars (a new tunable) is enabled (default is enabled),
then ignore the current BAR setting from the firmware and attempt to
allocate a fresh resource range for the BAR.
2) If 1) failed (or was disabled), disable decoding for the relevant
BAR type (e.g. disable mem decoding for a memory BAR) and emit a
warning if booting verbose.

all requested data was sent. The reason is that xfsize <= 0 condition
must not be tested at all if space == loopbytes. Otherwise, the done

Instead of moving the condition to exiting the inner loop after the
xfersize check, directly check for the completed transfer before the
testing of the available space in the socket buffer, and revert item 1
of r248830. It is arguably another bug to sleep waiting for socket
buffer space (or return EAGAIN for non-blocking socket) if all bytes
are already transferred.

bsnmp modules are located.
Section 3 (Library Functions) looks wrong for this manual page, which
contains only module description, that is why initially it was located
to section 8 (System Manager's Manual). On the other hand manual
pages for all other bsnmpd modules are already located in the section
3, and having all pages in one section looks more consistent. Also,
currently, similarly to manuals for other modules, snmp_hast manual
contains LIBRARY section, which is not good style for section 8.
