Only set the baudrate when it is different than what the device has
reported. In addition, pass in the args to effect no change to the other
parameters to the serial port. Some EFI firmware gets cranky when you
set them to the same value, so avoid doing so (we likely can remove the
HyperV workaround with this fix, but I kept it in place). Add comments
to the code for why we do this too.

Remove rtsdtr_off. It's basically unused. Expand its meaning, but put
changing flow control to under an ifdef. We shouldn't set it unless
we're sure we need to do so. UEFI normally initializes the device
correctly, and we should avoid needless changes that aren't user

Rename efiserialc to eficom.c and move it to libefi. Remove
loader.efi.h, since it's not needed. It's architecture independent
(though how we use it might vary). Drivers also belong in libfoo
in the boot loader: all the BIOS drivers are in i386/libi386 and
the console driver is in efi/libefi.

Add a compat shim for the "comconsole" name so that people with a
"console=comconsole" in their loader.conf on aarch64 will continue to
work (though with a warning).
This is only aarch64: it will never be there for amd64 (where comconsole
always means talk to the hardware directly). To do that is too hard.

Fix the 'renaming kludge' that we absolutely cannot do going forward
(it's cost us days of engineering time).
console=comconsole talks to the hardware directly. This is available
only on amd64. It is not available anywhere else (and so requires
changes for people doing comconsole on aarch64)
console=eficom talks to the console via EFI protocols. It's available
on amd64, aarch64 and riscv64. It's the first port that we find, though
it can be overriden by efi_com_port (which should be set to the UID of
the serial port, not the I/O port, despite the name). devinfo -v
will give the UID to uartX mapping.
This is an incompatible change for HYPER-V on amd64. It only works with
eficom console, so you'll need to change your configuration in
loader.conf. No compatibility hack will ever be provided for this (since
it requires renamig, which the loader cannot reliably do).
It's also an incompatible change for aarch64. comconsole will need to
change to eficom. There might be a comconsole "shim" for this.
All the interlock to keep only eficom and comconsole from both attaching
have been removed.

VLAN 0 essentially means "Treat as untagged, but with priority bits",
and is used by some ISPs.
On igb/em interfaces we did not receive packets with VLAN tag 0 unless
vlanhwfilter was disabled.
This can be fixed by explicitly listing VLAN 0 in the hardware VLAN
filter (VFTA). Do this from em_setup_vlan_hw_support(), where we already

If a file is specified in loader_conf_files that ends in '.lua', lualoader
will now load and execute that file. These may be used in place of a
traditional loader.conf to use more complicated logic, where some values
may be set based on others or based on the environment that the C bits has
left us with.
Lua scripts are run in a limited environment. In particular, it does not get
access to any modules or, in-fact, anything except environment variable.
A config.buildenv hook has been added so that a local module can add
whatever it may need to to the environment.
When a global var is set in the lua script, it does not immediately alter
the loader environment. Instead, the script's environment is initially
empty and processed only if the whole script executes successfully.
Effectively, a lua configuration file either takes effect or it does not,
an error will not leave it in a half-baked state.

It is nice to have, however, the location of this information means that
it will naturally be missed by developers adding or removing directories
to the layout, so it trends out-of-date and it is out-of-date.
The target audience for hier(7) is users and administrators. It is not
expected to be a place that programmers should go to learn about the
purposes of the different C headers provided by FreeBSD.
Program authors needing FreeBSD-specific interfaces or libraries
(#include <sys/queue.h>, for instance) will either be following a more
detailed man page, or consulting the header contents directly. Folks
targeting standardized headers (#include <sys/time.h>) will not need
hier(7) to tell them where those headers are under /usr/include.
In other words, this is more detail than necessary for this document.
I'd go as far as to say that many of the existing entries in this list
do little more than parrot the name of the directory.
With all this in mind, let's drop the maintenance burden.

Commit 281402e0a5 ("arm64: Shave off two instructions in exceptions")
removed the instruction that set the frame pointer (x29) as it appeared
to be unused.
The frame pointer is used in arm64/db_trace.c:db_stack_trace_cmd() when
unwinding state, and hence still needs to be set.
Add back the instruction to save_registers to properly update frame
pointer.

When performing an "upgrade" (moving between FreeBSD releases, as
opposed to "update" which merely applies security/errata updates
to the installed release) FreeBSD Update:
1. Generates a list of "files needing to be merged", namely those
files which don't match the version installed in the "old" release
and have paths matching the MergeChanges configuration directive
(by default, /boot/device.hints and everything under /etc/).
and later on,
2. Compares the currently-installed files to the versions in the
"new" release, removing index entries for files which "don't need
to be updated because they're not changing".
Unfortunately if a file falls into both of these categories -- that
is to say, if a file in /etc/ is the same as the version in the new
release and not the same as the version in the old release -- the
resulting "merge" step saw that the file was no longer listed as
being part of the new release, resulting in the file being deleted.
For the first 18 years of FreeBSD Update's existence, this never
happened, since $FreeBSD$ tags resulted in "new release" files
always being different from any files systems would already have
installed.
This commit fixes this behaviour by only placing a file into the
"files needing to be merged" list if it does not match the version
in the old release *or* the version in the new release.
