The PCI bwfm(4) chips have no TX rings in the traditional sense, as on
the actual rings we only share messages.  Sending a TX packet means
putting a message on the ring which contains a pktid (which for us maps
to an mbuf) and the physical address of the mbuf.  On jcs@'s macbook he
seems to run out of TX pktids pretty quickly during a speedtest.  This
would mean that there are 2048 TX packets in flight that we either want
to send out or that have not been "acked" by the firmware yet.  Either
way, recover from that situation when we hit that arbitrary limit by
restarting the queue after we free'd a packet from the TX pktid list.

Implement FUCKWIT for arm64; unmap the kernel almost entirely while userland
is running.  This provides protection against meltown on cores that are
vilnerable (just Cortex-A75 so far) but also seems to be an essential to
protect against spectre-like attacks against the kernel.

This implementation only exposes a single treampoline page that does not
contain any kernel virtual addresses and also hides the real virtual address
of the exception vectors, which helps on cores vulnerable to "variant 3a"
(Cortex-A57, Cortex-A72).  The implementation is inspired by the work done
by Will Deacon for Linux, but there are no knobs to turn it off.  The
overhead is fairly limited: around 3-4% slowdown on Cortex-A57.
