FDT attachment to a new file. A separate ACPI attachment will then be added
to allow arm64 servers with ACPI to use it over FDT.
This should also help with merging this with the ofwpci driver, with
further work needed to remove restrictions this driver places on resource
allocation.

(hopefully) stock gcc 4.2.1 on i386 and other arches.
In particular:
- Do not use %ebx in the asm constraints on i386, since rtld is
compiled with -fPIC and gcc cannot handle GOT-base register reload
(clang and newer gcc can).
- Avoid direct use of [static N] construct in the function
declaration/definion. In-tree gcc was patched to support this, but
stock 4.2.1 cannot handle the feature.

on the AES-NI code, and modified as needed for use on ARMv8. When loaded
the driver will check the appropriate field in the id_aa64isar0_el1
register to see if AES is supported, and if so the probe function will
signal the driver should attach.

When wcstof() skipped initial space and then parsing failed, it set
endptr to the first non-space character. Fix it to correctly report
failure by setting endptr to the beginning of the input string.
The fix is from theraven@, who fixed this bug in wcstod() and
wcstold() in r227753.
While I'm here:
Move assignments out of declarations in wcstod() and wcstold().
This is against my personal preference, but it is our agreed style(9).
Set endptr correctly on malloc() failure in all three functions.
Remove an incorrect comment: This is pointer arithmetic,
so the code was not actually making that assumption.
wcstold() advanced the wcp pointer beyond leading whitespace
and then reset it back to the beginning of the string.
Do not reset it. This seems to have no functional effect,
since strtold_l() also skips leading whitespace. I'm making
the change to keep this function consistent with wcstof() and
wcstod(), and because the C11 spec prescribes the use of iswspace()
to skip leading space.

- Do not set input flag when reading value from GPIO pin, it is not
required and for gpioc2(S5 bank) setting both input and output flags
leads to some kind of electric interference (curren drop?) that
causes USB devices to disconnect
- Check pad configuration when attaching device and provide IN/OUT
capabilities only for pads that are configured as GPIO. Do not let
user code to configure or change value of non-GPIO pads. There is
no information for NC bank in intel's datasheet so for now function

vmpage requires struct pmap to exist and contain a pm_stats field. As of
r308817, either AIM or BOOKE is required to be set in order to get their
respective pmap structs. Rather than expose them both, or try to unify them
unnecessarily, add a third option which contains only a pm_stats field, and
change the two existing pmap structures to place the common fields at the
beginning of the struct. This actually fixes the stats collection by libkvm on
AIM hardware, because before it was accessing a possibly different offset, which
would cause it to read garbage.
Bump __FreeBSD_version to denote this ABI change, so that ports which depend on
libkvm can be rebuilt.
and uses TCP for the Unmount RPC if the mount is over TCP.
Without this patch, umount does an Unmount RPC over UDP for all NFS mounts.

instead. Since we're little endian, we can get away with it. Also,
since the counters in quesitons would require billions of iops for
tens of billions of seconds to overflow, and since such data rates are
unlikely for people using i386 for a while, that's OK. The fastest
cards today can't do even a million IOPs.

Call Frame Optimization on i386 and libunwind, by disallowing the
optimization for i386-freebsd12.
This should fix some instances of broken exception handling when frame
pointers are omitted, in particular some unittests run during the build
of editors/libreoffice.
This hack will be removed as soon as upstream has implemented a more
permanent fix for this problem.
