3df058ffaf Add the GPIO driver for the ADI Engineering RCC-VE and RCC-DFF/DFFv2.
This driver allows read the software reset switch state and control the
status LEDs.

The GPIO pins have their direction (input/output) locked down to prevent
possible short circuits.

Note that most people get a reset button that is a hardware reset.  The
software reset button is available on boards from Netgate.

084748985d Separate ELFTOOLCHAIN_BOOTSTRAP from BINUTILS_BOOTSTRAP
For most cases they are equivalent, but BINUTILS_BOOTSTRAP is a
BROKEN_OPTION on arm64 as the in-tree GNU binutils do not support it,
so we need a separate internal flag for ELF Tool Chain.

646041a89a Add DEV_RANDOM pseudo-option and use it to "include out" random(4)
if desired.

Retire randomdev_none.c and introduce random_infra.c for resident
infrastructure. Completely stub out random(4) calls in the "without
DEV_RANDOM" case.

Add RANDOM_LOADABLE option to allow loadable Yarrow/Fortuna/LocallyWritten
algorithm.  Add a skeleton "other" algorithm framework for folks
to add their own processing code. NIST, anyone?

Retire the RANDOM_DUMMY option.

Build modules for Yarrow, Fortuna and "other".

Use atomics for the live entropy rate-tracking.

Convert ints to bools for the 'seeded' logic.

Move _write() function from the algorithm-specific areas to randomdev.c

Get rid of reseed() function - it is unused.

Tidy up the opt_*.h includes.

Update documentation for random(4) modules.

Fix test program (reviewers, please leave this).

347a39b4a6 Add support for the arrays in nvlist library.
- Add
  nvlist_{add,get,take,move,exists,free}_{number,bool,string,nvlist,
  descriptor} functions.
- Add support for (un)packing arrays.
- Add the nvl_array_next field to the nvlist structure.
  If an array is added by the nvlist_{move,add}_nvlist_array function
  this field will contains next element in the array.
- Add the nitems field to the nvpair and nvpair_header structure.
  This field contains number of elements in the array.
- Add special flag (NV_FLAG_IN_ARRAY) which is set if nvlist is a part of
  an array.
- Add special type (NV_TYPE_NVLIST_ARRAY_NEXT).This type is used only
  on packing/unpacking.
- Add new API for traversing arrays (nvlist_get_array_next).
- Add the nvlist_get_pararr function which combines the
  nvlist_get_array_next and nvlist_get_parent functions. If nvlist is in
  the array it will return next element from array. If nvlist is last
  element in array or it isn't in array it will return his
  container (parent). This function should simplify traveling over nvlist.
- Add tests for new features.
- Add documentation for new functions.
- Add my copyright.
- Regenerate the sys/cddl/compat/opensolaris/sys/nvpair.h file.

As the name indicates, these are flags to pass to nm(1).  The newer
binutils have a plugin mechanism so, to build something with LLVM's
LTO, we need to pass flags to nm(1).  This commit also extends
lorder(1) to pass NMFLAGS to nm(1).

cff0a327b8 Stop describing an acquire operation as a read barrier and a release
operation as a write barrier.  That description has never been correct,
and it has caused confusion.  An acquire operation orders writes as well
as reads, and a release operation orders reads as well as writes.

Also, explicitly say that a thread doesn't see its own accesses being
reordered.  The reordering of a thread's accesses is only (potentially)
visible to another thread.  Thus, memory barriers need only be used to
control the ordering of accesses between threads, not within a thread.

196d3019a8 Allow the choice of PPS signal captured by uart(4) to be runtime-configured,
eliminating the need to build a custom kernel to use the CTS signal.

The historical UART_PPS_ON_CTS kernel option is still honored, but now it
can be overridden at runtime using a tunable to configure all uart devices
(hw.uart.pps_mode) or specific devices (dev.uart.#.pps_mode).  The per-
device config is both a tunable and a writable sysctl.

This syncs the PPS capabilities of uart(4) with the enhancements recently
recently added to ucom(4) for capturing from USB serial devices.

Thanks to all the testers and to Adrian for his help with this

There's no MFC planned because the driver isn't very stable yet.

ddab052725 Disable SSE in libthr
Clang emits SSE instructions on amd64 in the common path of
pthread_mutex_unlock.  If the thread does not otherwise use SSE,
this usage incurs a context-switch of the FPU/SSE state, which
reduces the performance of multiple real-world applications by a
non-trivial amount (3-5% in one application).

Instead of this change, I experimented with eagerly switching the
FPU state at context-switch time.  This did not help.  Most of the
cost seems to be in the read/write of memory--as kib@ stated--and
not in the #NM handling.  I tested on machines with and without
XSAVEOPT.

One counter-argument to this change is that most applications already
use SIMD, and the number of applications and amount of SIMD usage
are only increasing.  This is absolutely true.  I agree that--in
general and in principle--this change is in the wrong direction.
However, there are applications that do not use enough SSE to offset
the extra context-switch cost.  SSE does not provide a clear benefit
in the current libthr code with the current compiler, but it does
provide a clear loss in some cases.  Therefore, disabling SSE in
libthr is a non-loss for most, and a gain for some.

I refrained from disabling SSE in libc--as was suggested--because
I can't make the above argument for libc.  It provides a wide variety
of code; each case should be analyzed separately.
