Queued async events handling in CAM opened race, that may lead to duplicate
AC_PATH_REGISTERED events delivery during boot. That was not happening
before r272935 because the driver was initialized later. After that change
it started create duplicate ports in CTL.
Target mode operation does not depend on the initiator mode scan process.
This change allows the target driver to attach earlier and receive some
async events (like AC_CONTRACT) that could be lost otherwise.

the value without recompiling the kernel. This is useful when
recompiling is not possible as an immediate solution. When we run out
of witness objects, witness is completely disabled. Not having an
immediate solution can therefore be problematic.

Such LUNs will be visible to initiators, but return "not ready" status
on media access commands. If backing storage become available later,
`ctladm modify ...` or `service ctld reload` can trigger its reopen.
FreeBSD segfaults on invalid pointers passed to getcwd because it throbs the
address passed in in libc, whereas NetBSD just passes the information off to
the syscall, which allows the kernel to return EFAULT on bad pointers.

compatible with write-locked path. Test for MAP_ENTRY_NOSYNC and set
VPO_NOSYNC for pages with dirty mask zero (this does not exclude a
possibility that the page is dirty, e.g. due to read fault on
writeable mapping and consequent write; the same issue exists in the
slow path).
Use helper vm_fault_dirty() to unify fast and slow path handling of
VPO_NOSYNC and setting the dirty mask.

The powerpc support was the only supported architecture not prepending the elf format name
with "-freebsd" in base this change makes it consistent with other architectures.
On newer version of binutils the powerpc format is also prepended with "-freebsd".
Also modify the kernel ldscripts in that regards.
As a result it is now possible cross build the kernel on powerpc using newer binutils

These are needed for the forthcoming vxlan implementation. The context
pointer means we do not have to use a spare pointer field in the inpcb,
and the source address is required to populate vxlan's forwarding table.
While I highly doubt there is an out of tree consumer of the UDP
tunneling callback, this change may be a difficult to eventually MFC.
