Add support for decoding pressed keys as a bitmap. The keys in the
bitmap are described in the interface specific HID descriptor. Some
keyboards even have multiple input interfaces, only using the bitmap
method when the event array is full. That typically means when more
than seven keys are pressed simultaneously.
The internals of the USB keyboard driver have been slightly reworked
to keep track of all keys in a single bitmap having 256 bits. This
bitmap is then divided into blocks of 64-bits as an optimisation.
Simplify automatic key repeat logic, because only the last key pressed
can be repeated.

Rotating and unmapped_io are really da flags. Convert them to a flag so it will
be reported with the other flags for the device. Deprecate the .rotating and
.unmapped_io sysctls in FreeBSD 14 and remove the softc ints.

fdatasync is essentially a subset of fsync (and may be exactly fsync,
depending on filesystem and development effort) and operates only on
a provided fd.

This is taken from the arm64 version, with the following simplifications:
- Our current pmap implementation uses a 3-level paging scheme
- The "mode" field has been omitted since RISC-V PTEs don't encode
typical mode attributes

In particular on amd64 this eliminates an atomic op in the common case,
trading it for IPIs in the uncommon case of catching CPUs executing the
code while the filesystem is getting suspended or unmounted.
This is a wrapper around smp_rendezvous_cpus which enables use of IPI
handlers which can fail and require retrying.
wait_func argument is added to to provide a routine which can be used to
poll CPU of interest for when the IPI can be retried.
Handlers which succeed must call smp_rendezvous_cpus_done to denote that
fact.

When the receive ring cannot be filled with mbufs, due to lack of memory,
no more interrupts may be generated to fill the receive ring later on.
Make sure to have a watchdog, to try refilling the receive ring from time
to time, hopefully when more mbufs are available.

It was saved from the initial purge of drivers in fcp-101 due to being
the onboard Ethernet device on a number of sparc64 machines. Now that
sparc64 is gone, it serves little purpose (PCI cards exist, but are rare
and are unlikely to have been deployed outside Sun systems).

From the beginning, ng_nat safely assumed cleansed traffic
because of limited ways it could be attached to NETGRAPH:
ng_ipfw or ng_ppp only.
Now as it may be attached with ng_ether too, the assumption proven wrong.
Add needed check to the ng_nat. Thanks for markj for debugging this.

An invalid value of priority will yield only in potential

This fixes compilation of ports/x11/nvidia-driver.
Maintain a count of free slabs in the per-domain keg structure and use
that to clear the free slab list in constant time for most cases. This
helps minimize lock contention induced by reclamation, in preparation
for proactive trimming of excesses of free memory.

When processing a taskqueue and a task has associated epoch, then
enter for duration of the task. If consecutive tasks belong to the
same epoch, batch them. Now we are talking about the network epoch
only.
Shrink the ta_priority size to 8-bits. No current consumers use
a priority that won't fit into 8 bits. Also complexity of
taskqueue_enqueue() is a square of maximum value of priority, so
we unlikely ever want to go over UCHAR_MAX here.
