PCB SP cache acquires extra reference, when SP is stored in the cache.
Release this reference when PCB is destroyed in ipsec_delete_pcbpolicy().
In ipsec_copy_pcbpolicy() release reference to SP in case if sp_in or
sp_out are not NULL.

before we increase irq again, or we'd end up choosing an irq, and then
really using the next one, even if it's not available.
Also in the inner loop, correct the end check so that we check every irq,
even the last one.
This makes the msk(4) adapter able to use MSI on Softiron Overdrive 1000.
This check has been redundant since it was introduced in r162554.

When this option is enabled, only gdb and kgdb are installed to
/usr/libexec for use by crashinfo(8). Other bits of GDB such as
gdbserver and gdbtui are not installed. For this option to be
effective, GDB must be enabled.
Rework r317094 to re-enable GDB on all platforms but enable
GDB_LIBEXEC on platforms for which the GDB in ports is a superset of
functionality.

patm(4) devices.
Maintaining an address family and framework has real costs when we make
infrastructure improvements. In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).
With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.
Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021. Improvements to the code in FreeBSD 11 are
certainly welcome.

The NFSv4 RFCs give a server the option of allowing the use of an open
stateid for write access to be used for a Read operation.
This patch enables this by default and adds a sysctl to disable it,
for anyone who does not want this capability.
Allowing this is particularily useful for a pNFS Data Server (DS), since
they are not permitted to allow the use of special stateids.
Discovered during recent testing of the pNFS server under development.

usr.bin/diff/diffreg.c: In function 'change':
usr.bin/diff/diffreg.c:1085: warning: 'i' may be used uninitialized in this function
This version of gcc is not smart enough to see that 'i' cannot actually
be used unitialized. However, the variable is confusingly re-used, so
it is better to give it another name, and clearly initialize it before
attempting to use it.

Hyper-V hot channel effect:
Operation latency on hot channel is only _half_ of the operation
latency on cold channels.
This commit takes the advantage of the above Hyper-V host channel
effect, and can reduce more than 75% latency and more than 50%
latency stdev, i.e. lower and more stable/predictable latency,

This patch sets the default uid/gid values for "nobody" and "nogroup"
to the values in the password and group databases. Normally nfsuserd(8)
will override these with whatever is in the password/group databases,
so these values are only used when the databases entries aren't available.
It would be nice to use the definitions in sys/conf.h, but those are
in the _KERNEL section of the file.

An NFSv4 server has the option of allowing a Read to be done using a Write
Open. If this is not allowed, the server will return NFSERR_OPENMODE.
This patch attempts the read with a write open and then disables this
if the server replies NFSERR_OPENMODE.
This change will avoid some uses of the special stateids. This will be
useful for pNFS/DS Reads, since they cannot use special stateids.
It will also be useful for any NFSv4 server that does not support reading
via the special stateids. It has been tested against both types of NFSv4 server.
