cxgbe/t4_tom: Exempt RDMA connections from a TCP sanity test for now, to
avoid panicking debug kernels.

t4_tom does not keep track of a connection once it switches to ULP mode
iWARP.  If the connection falls out of ULP mode the driver/hardware seq#
etc. are out of sync.  A better fix would be to figure out what the
current seq# are, update the driver's state, and perform all sanity
checks as usual.

exec: Cease tracing if credentials will change with the new image.

This also prevents tracing to a P_INEXEC process since it could race
with other processes attaching to it in filemon_event_process_exec() due
to the filemon_get_proc() race of incrementing ref and then locking the
filemon.  With the no-P_INEXEC invariant in place the p_filemon may only
be the same or NULL when trying to drop it in
filemon_event_process_exec().

Fix taskqueue groups to work with EARLY_AP_STARTUP.

In the EARLY_AP_STARTUP case the APs are already running when a taskqgroup
is created, so adjust the group at the same time it is created.

iw_cxgbe: Plug a lock leak in process_mpa_request().

If the parent is DEAD or connect_request_upcall() fails, the parent
mutex is left locked.  This leads to a hang when process_mpa_request()
is called again for another child of the listening endpoint.

300886 by bdrewery:
Move external GCC compiler hacks to bsd.sys.mk.

This allows respecting -nostdinc, -nostdinc++ and -nostdlib before
making the decision to add in -isystem, etc.  The -isystem flags
are problematic for building lib/libc++ and lib/libcxxrt which wants
to only use its own headers.

More information the need of these flags can be found at
https://gcc.gnu.org/ml/gcc/2016-03/msg00219.html

This also reverts r300873.

300885 by bdrewery:
Libcompat: Only pass -isystem =/usr/include for external GCC.

This is the same as the main build logic.  GCC with a cross-compiler
requires using -isystem to =/usr/include to get the search order
correct.

Fix up r300870

The sys/types.h fix I proposed was only tested with zfs(4), not with
libzpool, which is where the build failure actually existed

Remove vm/vm_pageout.h from arc.c and zfs_vnops.c because they're both
unneeded

Always create loopback routes on every fib

Always create loopback routes on every fib, for both IPv4 and IPv6

etc/rc.d/routing
	Create loopback IPv4 and IPv6 routes on every fib at boot. Revert
	278302; now that all FIBs have IPv6 loopback routes, the
	"route add -reject" commands won't fail.

tests/etc/rc.d/routing_test.sh
	Greatly simplify static_ipv6_loopback_route_for_each_fib. It was
	written under the assumption that loopback routes would be added to
	a given fib by the kernel as soon as an interface is configured on
	that fib. However, the logic can be much simpler now that we simply
	add loopback routes to all fibs at boot. This also removes the need
	to run the test as root, removes the restriction that
	net.add_addr_allfibs=0, and removes the need to configure fibs in
	kyua.conf.

	Also, add a test case for IPv4 loopback routes

Avoid issuing spa config updates for physical path when not necessary

ZFS's configuration needs to be updated whenever the physical path for a
device changes, but not when a new device is introduced. This is because new
devices necessarily cause config updates, but only if they are actually
accepted into the pool.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c
	Split vdev_geom_set_physpath out of vdev_geom_attrchanged.  When
	setting the vdev's physical path, only request a config update if
	the physical path has changed.  Don't request it when opening a
	device for the first time, because the config sync will happen
	anyway upstack.

sys/geom/geom_dev.c
	Split g_dev_set_physpath and g_dev_set_media out of
	g_dev_attrchanged

Strip leading spaces off of a SCSI disk's serial number

sys/cam/scsi/scsi_xpt.c
	Strip leading spaces off of a SCSI disk's reported serial number
	when populating the CAM serial number. This affects the output of
	"diskinfo -v" and the names of /dev/diskid/DISK-* device nodes,
	among other things.

	SPC5r05 says that the Product Serial Number field from the Unit
	Serial Number VPD page is right-aligned. So any leading spaces are
	not part of the actual serial number. Most devices don't left-pad
	their serial numbers, but some do. In particular, the SN VPD page
	that an LSI HBA emulates for a SATA drive contains enough
	left-padding to fill a 20-byte field.

UPDATING
	Add a note to UPDATING, because some users may have to update
	/etc/fstab or geom labels.
