2abd4f8581 Add a way to map arm64 non-posted device memory
On arm64 we currently use a non-posted write for device memory, however
we should move to use posted writes. This is expected to work on most
hardware, however we will need to support a non-posted option for some
broken hardware.

4ce1ba6523 sndstat: nvlist schema and API definition changes
- SNDSTAT_LABEL_* are renamed to SNDST_DSPS_*, and SNDSTAT_LABEL_DSPS
  becomes SNDST_DSPS.
- Centralize channel number/rate/formats into a single nvlist
  The above nvlist is named "info_play" and "info_rec"
- Expose only encoding format in pfmts/rfmts. Userland has no direct
  access to AFMT_ENCODING/CHANNEL/EXTCHANNEL macros, thus it serves no
  meaning to expose too much information through this pair of labels.
  However pminrate/rminrate, pmaxrate/rmaxrate, pfmts/rfmts are
  deprecated and will be removed in future.

This commit keeps ioctls ABI compatibility with __FreeBSD_version
1400006 for now. In future the compat ABI with 1400006 will be removed
once audio/virtual_oss is rebuilt.

under SYN flood. To mitigate that add a sysctl that would make
syncache(4) globally visible, ignoring UID/GID, jail(2) and mac(4)
checks. When turned on, we won't need to call crhold() on the listening
socket credential for every incoming SYN packet.

aabe13f145 uma: Introduce per-domain reclamation functions
Make it possible to reclaim items from a specific NUMA domain.

- Add uma_zone_reclaim_domain() and uma_reclaim_domain().
- Permit parallel reclamations.  Use a counter instead of a flag to
  synchronize with zone_dtor().
- Use the zone lock to protect cache_shrink() now that parallel reclaims
  can happen.
- Add a sysctl that can be used to trigger reclamation from a specific
  domain.

Currently the new KPIs are unused, so there should be no functional
change.

38da497a4d Add the KASAN runtime
KASAN enables the use of LLVM's AddressSanitizer in the kernel.  This
feature makes use of compiler instrumentation to validate memory
accesses in the kernel and detect several types of bugs, including
use-after-frees and out-of-bounds accesses.  It is particularly
effective when combined with test suites or syzkaller.  KASAN has high
CPU and memory usage overhead and so is not suited for production
environments.

The runtime and pmap maintain a shadow of the kernel map to store
information about the validity of memory mapped at a given kernel
address.

The runtime implements a number of functions defined by the compiler
ABI.  These are prefixed by __asan.  The compiler emits calls to
__asan_load*() and __asan_store*() around memory accesses, and the
runtime consults the shadow map to determine whether a given access is
valid.

kasan_mark() is called by various kernel allocators to update state in
the shadow map.  Updates to those allocators will come in subsequent
commits.

The runtime also defines various interceptors.  Some low-level routines
are implemented in assembly and are thus not amenable to compiler
instrumentation.  To handle this, the runtime implements these routines
on behalf of the rest of the kernel.  The sanitizer implementation
validates memory accesses manually before handing off to the real
implementation.

The sanitizer in a KASAN-configured kernel can be disabled by setting
the loader tunable debug.kasan.disable=1.

types.h defines device_t as a typedef of struct device *.  struct device
is defined in subr_bus.c and almost all of the kernel uses device_t.
The LinuxKPI also defines a struct device, so type confusion can occur.

This causes bugs and ambiguity for debugging tools.  Rename the FreeBSD
struct device to struct _device.
