armv6 and armv7 systems already were 1000Hz. The other armv5 were a
mix of 100 and 1000. This changes them to 1000. Should there be
issues, we can add options HZ=100 to the systems that have bad
performance at the drop of a hat.
mips is a lot more complicated. But most of the systems are already
1000HZ. The hardware exceptions are all fast enough to run at
1000Hz. MALTA is our primary emulator, and history has shown emulators
tend to like 100Hz better, so run those systems at 100Hz. As with arm,
any system that shows a huge performance regression can reverted to
100Hz easily.
This was going to be committed well in advance of the 13 branch, but
it was delayed and forgotten til now.

Some changes back in ye olde times somewhere has changed the default
block size the flash device exposes. So, the default geom redboot

is no longer finding it.
So, force it to probe at the last 64k of flash regardless of the
underlying flash block size.

This does an import of quirk stubs, debugging macros from USB code and
numerous usage constants used by dependent drivers.
Besides, this change renames some functions to get a better matching
with userland library and NetBSD/OpenBSD HID code. Namely:
- Old hid_report_size() renamed to hid_report_size_max()
- New hid_report_size() calculates size of given report rather than
maximum size of all reports.
- hid_get_data_unsigned() renamed to hid_get_udata()
- hid_put_data_unsigned() renamed to hid_put_udata()
Compat shim functions are provided in usbhid.h to make possible compile
of legacy code unmodified after this change.

So it turns out that sometime in the past I removed the GPIO bits here
and was going to move it into a module in order to save a little space.
However, it turns out that was a mistake on this particular AP - it
uses a pair of GPIO lines to control the two receive LNAs on the 2GHz
radio and without them enabled the radio is a LOT DEAF.
With this re-introduced (and some replacement userland tools to save
space, *cough* cpio/libarchive) I can actually use these chipsets
again as a 2G station. Without the LNA the AP was seeing a per-radio
RSSI upstairs here of around 3-5dB, with the LNA on it's around 15dB,
more than enough to actually use wifi upstairs and also in line with
the other Atheros / Intel devices I have up here.
Big oopsie to Adrian. Big, big oopsie.
- Use a default -march of mips64 on N64 and N32 kernels.
- Set the endianness (via MIPS_ENDIAN) and ABI (via MIPS_ABI) in
CFLAGS from MACHINE_ARCH. ARCH_FLAGS now only sets a different
-march value if needed.
- TRAMP_ARCH_FLAGS inherits MIPS_ENDIAN from MACHINE_ARCH but does
not set the ABI since XLPN32 needs an N64 ABI for the trampoline
loader. When TRAMP_ARCH_FLAGS is used it must set both -march
and -mabi.

tun(4) and tap(4) share the same general management interface and have a lot
in common. Bugs exist in tap(4) that have been fixed in tun(4), and
vice-versa. Let's reduce the maintenance requirements by merging them
together and using flags to differentiate between the three interface types
(tun, tap, vmnet).
This fixes a couple of tap(4)/vmnet(4) issues right out of the gate:
- tap devices may no longer be destroyed while they're open [0]
- VIMAGE issues already addressed in tun by kp
[0] emaste had removed an easy-panic-button in r240938 due to devdrn
blocking. A naive glance over this leads me to believe that this isn't quite
complete -- destroy_devl will only block while executing d_* functions, but
doesn't block the device from being destroyed while a process has it open.
The latter is the intent of the condvar in tun, so this is "fixed" (for
certain definitions of the word -- it wasn't really broken in tap, it just
wasn't quite ideal).
ifconfig(8) also grew the ability to map an interface name to a kld, so
that `ifconfig {tun,tap}0` can continue to autoload the correct module, and
`ifconfig vmnet0 create` will now autoload the correct module. This is a
low overhead addition.
(MFC commentary)
This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this,
and how critical they are. Changes after this are likely easily MFC'd
without taking this merge, but the merge will be easier.
I have no plans to do this MFC as of now.

As discussed in that commit message, it is a dangerous default. But the
safe default causes enough pain on a variety of platforms that for now,
restore the prior default.
Some of this is self-induced pain we should/could do better about; for
example, programmatic CI systems and VM managers should introduce entropy
from the host for individual VM instances. This is considered a future work
item.
On modern x86 and Power9 systems, this may be wholly unnecessary after
D19928 lands (even in the non-ideal case where early /boot/entropy is
unavailable), because they have fast hardware random sources available early
in boot. But D19928 is not yet landed and we have a host of architectures
which do not provide fast random sources.
This change adds several tunables and diagnostic sysctls, documented
thoroughly in UPDATING and sys/dev/random/random_infra.c.

Embedded lzma decompression library becomes a module usable by other
consumers, in addition to geom_uzip.
Most important code changes are
- removal of XZ_DEC_SINGLE define, we need the code to work
with XZ_DEC_DYNALLOC;
- xz_crc32_init() call is removed from geom_uzip, xz module handles
initialization on its own.
xz is no longer embedded into geom_uzip, instead the depend line for
the module is provided, and corresponding kernel option is added to
each MIPS kernel config file using geom_uzip.
The commit also carries unrelated cleanup by removing excess "device geom_uzip"
in places which were missed in r344479.

It looks like the intent was to allow ZSTD support to be

like that was ever implemented or I'm missing how to do it.
I did a cursory audit of kernel config files and made a decision to
enable ZSTDIO in riscv GENERIC and mips MALTA configurations. All other
kernel configurations already had this option in their kernel configs
but they didn't do anything useful as the feature was declared as
"standard" prior to this.
