This is similar to 5d48fb3b16c1496bf415fee620c61cc944b0326d.
With LLVM14 the .data.rel.ro ELF section appears after .data,
making loader behave erractly and kernel is not loaded.
This patch makes ensures the correct order.

Replace the DMAR unit's tlb_flush TAILQ by a custom list implementation

lock.

Upgrade the argument of (*bss_info_changed) mac80211 ops function call
from 32 to 64 bit.
Add an extra argument to ieee80211_beacon_get_template().

Both changes are needed in order to keep other out-of-tree drivers in
synch and to move forward.

The driver changes were extracted from Linux wireless-testing

The devmap variants used vm_offset_t for some reason, and a few places
explicitly cast bus addresses to vm_offset_t.  (Probably those casts
along with similar casts for vm_size_t should just be removed and
instead permit the compiler to DTRT.)

Put the console into raw mode on startup. This allows the menus to work
as expected. Boot is now interruptable.

Note: Likely should restore the terminal settings on most exists.  It's
not clear the best way to do this, and most shells have an auto stty
sane anyway, so note it for future improvement.

Implement a stripped down termios, obtained from various files in musl
and HOST_ or host_ prepended to most things and a few unavoidable style
tweaks. Only implements the bits of termios we need for the boot loader:
put the terminal into raw mode, restore terminal settings and speed
stuff.

Clients of libsa are expected to implement exit(). The current exit just
loops forever. It is better to really exit: when running as init that
will reboot the system. When not running as init, other programs can
recover (not that we support running as init, but when we do in the
future, this is still the rigtht thing).

Add support for aarch64. exec.c and ldscript are copied from the EFI
version with #ifdefs for the differences. Once complete, I'll refactor
them. host_syscall.S implements a generic system call. tramp.S is a
first attempt to create a tramoline that we can use to jump to the
aarch64 kernel. Add aarch64-specific startup and stat files as well.
exec.c tweaked slightly to avoid bringing in bi_load(), which will come
in later. Includes tweaks to stat due to name differences between names
on different Linux architectures.

In the current implementation of altq_hfsc.c, whne new queues are being
added (by pfctl), each queue is added to the tail of the siblings linked
list under the parent queue.

On a system with many queues (50,000+) this leads to very long load
times at the insertion process must scan the entire list for every new
queue,

Since this list is unordered, this changes merely adds the new queue to
the head of the list rather than the tail.

After the addition of SV48 support, VIRT_IS_VALID() did not exclude
addresses that are in the SV39 address space hole but not in the SV48
address space hole.  This can result in mishandling of accesses to that
range when in SV39 mode.

Fix the problem by modifying VIRT_IS_VALID() to use the runtime address
space bounds.  Then, if the address is invalid, and pcb_onfault is set,
give vm_fault_trap() a chance to veto the access instead of panicking.
