All existing callers guarantee that the page does not have a
pre-existing dequeue pending. Thus, if the page is dequeued before
pqbatch_submit() acquires the page queue lock, we do not need to do
anything since vm_page_dequeue_complete() takes care of clearing all
page queue state flags for us.
With this change, vm_page_pqbatch_submit() has the nice property that it
does not directly modify any fields in the page structure.

It will become useful for the page daemon to be able to directly create
a batch queue entry for a page, and without modifying the page
structure. Rename vm_pqbatch_submit_page() to vm_page_pqbatch_submit()
to keep the namespace consistent. No functional change intended.

As discussed on arch@, gcc 4.2.1 is on its way out. Turn off Werror on gcc
versions < 5.0 permantly. This will allow older platforms to continue to compile
w/o new errors once we take them out of universe by default. This will also free
developers from chasing down obsolete warnings that produce no beneficial
changes to the source.

The Linux lockdep API assumes LA_LOCKED semantic in lockdep_assert_held(),
meaning that either a shared lock or write lock is Ok. On the other hand,
the timeout code uses lc_assert() with LA_XLOCKED, and we need both to
work.
For mutexes, because they can not be shared (this is unique among all lock
classes, and it is unlikely that we would add new lock class anytime soon),
it is easier to simply extend mtx_assert to handle LA_LOCKED there, despite
the change itself can be viewed as a slight abstraction violation.

Ouput format of last(1) is broken for non UTF-8 locales
since it got libxo(3) support. It uses strftime(3) that produces
non UTF-8 strings passed to xo_emit(3) with wrong %s format -
it should be %hs in this case, so xo_emit(3) produces empty output.
This change is basically no-op when locale is of UTF-8 type,

It fixes output for other locales.

queues, don't try to tear them down in the ctrlr_destroy
path. Otherwise, we dereference queue structures that are NULL and we
trap.
This fix is incomplete: we leak IRQ and MSI resources when this
happens. That's preferable to a crash but still should be fixed.
machine/regnum.h ends up being included by sys/procfs.h and sys/ptrace.h via
machine/reg.h. Many of the regnum definitions are too short and too generic
to be exposing to any userland application including one of these two
headers. Moreover, these actively cause build failures in googletest
(template <typename T1 ...> expanding to template <typename 9 ...>).
Hide the definitions behind _KERNEL or _WANT_MIPS_REGNUM, and patch all of
the userland consumers to define as needed.

since kldxref properly handles that case.
Turn off bus master after we detach the device (to match the prior
order). Release MSI after we're done detaching and have turned off
all the interrupts. Otherwise this may cause problems as other threads
race nvme_detach. This more closely matches the old order.

ENOTTY is not listed as an error return by either the lseek(2) man page

This streams out an XML document over several GDB packets describing all
threads in the system; their ids, name, and any loosely defined "extra info"
we feel like including. For now, I have included a string version of the run
state, similar to some of the DDB logic to stringify thread state.
The benefit of supporting this in addition to the qfThreadInfo/qsThreadInfo
packing is that in this mode, the host gdb does not ask for every thread's
"qThreadExtraInfo," saving per-thread round-trips on "info threads."
To use this feature, (k)gdb needs to be built with the --with-expat option.
I would encourage enabling this option by default in our GDB port, if it is
not already.
Finally, there is another optional attribute you can specify per-thread
called a "handle." Handles are arbitrarily long sequences of bytes,
represented in the XML as hexadecimal. It is unclear to me how or if GDB
actually uses handles for anything. So I have left them out.
