Add support for the SCTP_PR_STREAM_STATUS and SCTP_PR_ASSOC_STATUS
socket options. This includes managing the correspoing stat counters.
Add the SCTP_DETAILED_STR_STATS kernel option to control per policy
counters on every stream. The default is off and only an aggregated
counter is available. This is sufficient for the RTCWeb usecase.

Supplement r259111 by also using correct casts in gcc's emmintrin.h for
the first argument of the following builtin function:

* __builtin_ia32_psrlqi128() takes __v2di instead of __v4si

This should fix the following errors when building the graphics/webp
port with base gcc:

lossless_sse2.c:403: error: incompatible type for argument 1 of '__builtin_ia32_psrlqi128'
lossless_sse2.c:404: error: incompatible type for argument 1 of '__builtin_ia32_psrlqi128'

Copy country-code .iso syscons keymaps for vt(4)

Existing syscons ISO 8859-1 keymaps (??.iso.kbd) are usable without
change as Unicode keymaps for vt(4).

Make the libbsdstat useful again.
Remove trailing whitespace
Use "NO NAME" as the default unnamed label.

Microsoft recommends avoiding the use of spaces in the
string structures for FAT. Unfortunately they do just
that by default in the case of unlabeled filesystems.

Follow the default MS behavior to avoid confusion in
common tools like file(1). This was actually the
default behavior before r203868.

Stop telling people to directly report llvm or clang bugs upstream,

Stop using __FreeBSD_ARCH_armv6__ and switch to __ARM_ARCH >= 6 in the
couple of places in tree. clang already implements ACLE. Add a define
that says we implement version 1.1, even though the implementation
isn't quite complete.
Add support for FDT and !FDT configs on Atmel, though FDT isn't
working yet.
Bump rev on arm Makefile since files.at91 uses new '!' operator.
Start to add FDT support.
Add support for multipass to Atmel, for both FDT and !FDT cases.
Add AIC to at91sam9260 support, now that it is needed for multipass to
work. This gets my AT91SAM9260-based boards almost booting with
current in multi pass. The MCI driver is broken, but it is equally
broken before multi-pass.
Bump version because challenge buffer size changed

Use the max guest memory address when creating its iommu domain.

Also, assert that the GPA being mapped in the domain is less than its maxaddr.

Re-instate UMA cached backend for 4K - 64K allocations.  New consumers
like geli(4) uses malloc(9) to allocate temporary buffers that gets

Add a new loader tunable, vm.kmem_zmax which allows a system administrator

Fix euro symbol in copied keymaps

These were copied from share/syscons/keymaps/??.iso.kbd.  They were
not actually ISO 8859-1 as assumed.  When interpreted as Unicode they
ended up with the generic currency sign (U+00A4) instead of the euro
(U+20AC).
