Tested:
* rum0: MAC/BBP RT2573 (rev 0x2573a), RF RT2528, STA mode
Note: haven't tested AP mode yet; will do once the rest of the
AP mode / power save commits are in.

IFF_UP && !IFF_DRV_RUNNING.
- nd6_dad_starttimer() now calls nd6_dad_ns_output(), instead of
calling it before nd6_dad_starttimer().
- Do not release an entry in dadq when a duplicate entry is being
added.
Before r278702 prefetch was blocked for I/Os > 1MB, after -- >= 1MB.
1MB I/Os are used for bulk operations in CTL (XCOPY, VERIFY), and disabling
prefetch for them reduced the performance.
This is temporary local patch, that should be replaced when upstreamed.

* Remove unused sc_txtap_len/sc_rxtap_len fields.
* Remove unused ackrate variable.
* Remove unneded warning in rum_update_mcast().
* Use nitems().
* Replace some hardcoded values for RT2573_MAC_CSR1 register.
* Remove second argument for RUM_LOCK_ASSERT() - it is always the same.

This can be used to update IV state for the caller without adding
information to the mbuf. Some hardware (eg rum) apparently requires
bits of this.

self-consistent, there is no need in anything but compiler barrier in
the implementation of atomic_thread_fence_*() on ARMv5. Split
implementation of fences for ARMv4/5 and ARMv6; the former use
compiler barriers, the later also perform hardware barriers.
An issue which is fixed by the change is the faults from the CP15
coprocessor accesses in the user mode. This was uncovered by the
pthread_once() changes in r287556.

recently added error checks return immediately instead of jumping to a
label resulting in leaks. Fix these to jump to a label to do cleanup
instead.

missed. In other words, if a new request for an IPI is sent while the
previous request is being handled but the IPI is not cleared yet, the
clearing of the previous IPI request also clears the new one and the
handling is missed.
There are only three MP interrupt controllers in ARM now. Two of them are
fixed by this change, the third one is correct, probably only just by
accident. The fix is minimalistic as new interrupt framework is awaited.
It was debugged on RPi2 where missing IPI handling together with SCHED_ULE
led to situation in which tdq_ipipending was not cleared and so IPI_PREEMPT
was stopped to be sent. Various odditys were found related to slow system
response time like various events timed out, and slow console response.

with a laptop overheating or the battery dying.
The implementation uses a new sysctl, kern.suspend_blocked; init(8) sets
this while rc.suspend runs, and the ACPI sleep code ignores requests while
the sysctl is set.

of POSIX_FADV_DONTNEED so that it causes the backing pages to be moved to
the head of the inactive queue instead of being cached.
This affects the implementation of POSIX_FADV_NOREUSE as well, since it
works by applying POSIX_FADV_DONTNEED to file ranges after they have been
read or written. At that point the corresponding buffers may still be
dirty, so the previous implementation would coalesce successive ranges and
apply POSIX_FADV_DONTNEED to the result, ensuring that pages backing the
dirty buffers would eventually be cached. To preserve this behaviour in an
efficient manner, this change adds a new buf flag, B_NOREUSE, which causes
the pages backing a VMIO buf to be placed at the head of the inactive queue
when the buf is released. POSIX_FADV_NOREUSE then works by setting this
flag in bufs that underlie the specified range.

Currently we perform crypto requests for IPSEC synchronous for most of
crypto providers (software, aesni) and only VIA padlock calls crypto
callback asynchronous. In synchronous mode it is possible, that security
policy will be removed during the processing crypto request. And crypto
callback will release the last reference to SP. Then upon return into
ipsec[46]_process_packet() IPSECREQUEST_UNLOCK() will be called to already
freed request. To prevent this we will take extra reference to SP.
