APM BIOS was relevant only to early laptops (approximately P166 or
P200 and slower). These have not been relevant for a long time, and
this code has been untested for a long time (as far as I can
tell). The APM compat code in ACPI and the apm(8) command is not being
retired. Both of these items are still in use (apm(8) is more
scriptable than the replacement acpiconf, for the most part). This has
been commented out of i386 GENERIC since 2002. This code is not

Many arm kernel configs bogusly specified WERROR=-Werror. There's no
reason for this because the default is that and there's no reason to
override. These date from a time when we needed to add additional
warning->error suppression. They are obsolete and were cut and paste
propagated from file to file.
Comment out all the WERROR=.... lines in powerpc. They aren't bogus,
but were appropriate for the old defaults for gcc4.2.1. Now that we've
made the policy decision to suppress -Werror by default on these
platforms, it is appropriate to comment these out. People wishing to
fix these errors can still un-comment them out, or say WERROR=-Werror
on the command line.
Fix two instances (cut and paste propagation) of hard-coded -Werror
in x86 code. Replace with ${WERROR} instead. This is a no-op change
except for people who build WERROR=-Wno-error :).
This should fix tinderbox / CI breakage.

The goal of this driver is consolidate information about SuperIO chips
and to provide for peaceful coexistence of drivers that need to access
SuperIO configuration registers.
While SuperIO chips can host various functions most of them are
discoverable and accessible without any knowledge of the SuperIO.
Examples are: keyboard and mouse controllers, UARTs, floppy disk
controllers. SuperIO-s also provide non-standard functions such as
GPIO, watchdog timers and hardware monitoring. Such functions do
require drivers with a knowledge of a specific SuperIO.
At this time the driver supports a number of ITE and Nuvoton (fka
Winbond) SuperIO chips.
There is a single driver for all devices. So, I have not done the usual
split between the hardware driver and the bus functionality. Although,
superio does act as a bus for devices that represent known non-standard
functions of a SuperIO chip. The bus provides enumeration of child
devices based on the hardcoded knowledge of such functions. The
knowledge as extracted from datasheets and other drivers.
As there is a single driver, I have not defined a kobj interface for it.
So, its interface is currently made of simple functions.
I think that we can the flexibility (and complications) when we actually
need it.
I am planning to convert nctgpio and wbwd to superio bus very soon.
Also, I am working on itwd driver (watchdog in ITE SuperIO-s).
Additionally, there is ithwm driver based on the reverted sensors
import, but I am not sure how to integrate it given that we still lack
any sensors interface.

I introduced an obvious compiler error in r346282, so this change fixes
that.
Unfortunately, RANDOM_LOADABLE isn't covered by our existing tinderbox, and
it seems like there were existing latent linking problems. I believe these
were introduced on accident in r338324 during reduction of the boolean
expression(s) adjacent to randomdev.c and hash.c. It seems the
RANDOM_LOADABLE build breakage has gone unnoticed for nine months.
This change correctly annotates randomdev.c and hash.c with !random_loadable
to match the pre-r338324 logic; and additionally updates the HWRNG drivers
in MD 'files.*', which depend on random_device symbols, with
!random_loadable (it is invalid for the kernel to depend on symbols from a
module).
(The expression for both randomdev.c and hash.c was the same, prior to
r338324: "optional random random_yarrow | random !random_yarrow
!random_loadable". I.e., "random && (yarrow || !loadable)." When Yarrow
was removed ("yarrow := False"), the expression was incorrectly reduced to
"optional random" when it should have retained "random && !loadable".)
Additionally, I discovered that virtio_random was missing a MODULE_DEPEND on
random_device, which breaks kld load/link of the driver on RANDOM_LOADABLE
kernels. Address that issue as well.

Move scvtb.c similarly. It is needed whenever sc is configured, and is

This only changes the combined list for arm64 and mips. These arches

Effectively all i386 kernels now have two pmaps compiled in: one
managing PAE pagetables, and another non-PAE. The implementation is
selected at cold time depending on the CPU features. The vm_paddr_t is
always 64bit now. As result, nx bit can be used on all capable CPUs.
Option PAE only affects the bus_addr_t: it is still 32bit for non-PAE
configs, for drivers compatibility. Kernel layout, esp. max kernel
address, low memory PDEs and max user address (same as trampoline
start) are now same for PAE and for non-PAE regardless of the type of
page tables used.
Non-PAE kernel (when using PAE pagetables) can handle physical memory
up to 24G now, larger memory requires re-tuning the KVA consumers and
instead the code caps the maximum at 24G. Unfortunately, a lot of
drivers do not use busdma(9) properly so by default even 4G barrier is
not easy. There are two tunables added: hw.above4g_allow and
hw.above24g_allow, the first one is kept enabled for now to evaluate
the status on HEAD, second is only for dev use.
i386 now creates three freelists if there is any memory above 4G, to
allow proper bounce pages allocation. Also, VM_KMEM_SIZE_SCALE changed
from 3 to 1.
The PAE_TABLES kernel config option is retired.
