ACPI is not handled specially by sys/conf/kern.opts.mk (unlike a few
options), so we should fall back on the generic behavior of
sys/conf/config.mk, which pulls from all the generated opt*.h files,
including opt_acpi.h, which will cause DEV_ACPI to be included in
KERN_OPTS. Then the generic machinery in sys/conf/kmod.mk will cause
SRCS.DEV_ACPI to be included in SRCS when appropriate.

This patch shaves off up to two three instructions in
save_registers_head in exception.S for arm64, which would make more
space for instructions that could be added in CheriBSD.
This is done by:
1. Combining pointer arithmetic with pre-incrementing STP instructions
2. Removing the instruction that sets the frame pointer (x29) as its
content is unused

Mapping the framebuffer with WC (Write Combined) memory type can, in
practice, cause some memory transactions to be rate-limited at a
fraction of the fb write rate. WC allows one core to queue up many
globally visible write transactions, and in the process some unrelated
transactions may end up having to wait for all of the queued up PCI
writes to be flushed.
Add an hw.efifb.cache_attr tunable to allow mapping the framebuffer as
uncacheable instead. We should likely be taking a more careful approach
of checking the memory map to determine which cacheability attributes
are feasible, but the knob lets us use our historically functional
behavior while offering a convenient way to switch on a stock kernel.
The only valid values for hw.efifb.cache_attr at this time are "uc" and
"wc".

Reflect the fact that ipfilter was moved from contrib to netpfil
on December 20, 2021 by 3b9b51fe46. And that ipfilter userland
was moved from contrib to sbin/ipf by 41edb306f0 that same day.
This corrects a bug in which the daily periodic script '310.accounting'
attempts to rotate logs via /etc/rc.d/accounting by calling
onerotate_logs function. The rotate logs function turns accounting back
on regardless of what acccounting_enable is set to in /etc/rc.conf. This
is due to checkyesno always returning YES since rotate logs is called
with the 'one' prefix.
In effect, accounting will always be turned back on once a day even if
it is disabled and stopped by hand. The fix was simple, just check if
accounting is before rotating logs and if it is, don't attempt the
rotate.

The growfs_fstab script has been testing dumpdev, and if it is AUTO,
enables dumps on the newly-added swap device for the initial boot.
However, dumpdev defaults to AUTO on main, but NO on stable/13 and
release branches. On the other hand, bsdinstall adds dumpdev="AUTO"
by default (controlled by a menu item). bsdinstall is not used when
booting an SD card or other disk image. Adopt the default from
bsdinstall, and set dumpdev to AUTO in /etc/rc.conf in the
growfs_fstab script if a swap partition has been added, along with
the explanatory comment added by bsdinstall.

Qemu defines some common fwcfg items. We don't need to support all of
them. Only a subset needs to be present for fwcfg to work properly.
- signature
The signature is used by the guest to check if qemu's fwcfg is
available or not.
- id
The id is used by the guest to check which features are supported by
the fwcfg implementation of the hypervisor.
- file_dir
The file dir reports all fwcfg items which don't have a fixed index.
These are mostly user defined fwcfg items.
