If we hit an error at this level, we are almost certainly not in any kind
of sane state where autoboot can do the right thing. Instead of letting it
try and probably failing, disable autoboot so they immediately get kicked
into a loader prompt for manual remediation/diagnosis.

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 FreeBSD the bits that disabled stats
when netflix-stats is not defined is no longer
needed. Lets remove these bits so that we
will properly use stats per its definition

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.

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.
