Use MACHINE_CPUARCH with arm64 (aarch64) when we build code that could run
on any 64-bit Arm instruction set. This will simplify checks in downstream
consumers targeting prototype instruction sets.
The only place we check for MACHINE_ARCH == aarch64 is when building the
device tree blobs. As these are targeting current generation ISAs.

Currently, the only thing that prevents a functioning 64-bit FICL build is
a few integer types that were intended to be fixed-width.
Changing them to C99 integer types allows building a functioning 64-bit
FICL.
While this isn't applicable to the default settings of any in-tree loaders,
it is necessary for a future Petitboot loader, due to the requirement that
it be compiled as a 64-bit program.

On ibm,extended-clock-frequency, ensure we be64toh() the value.
On clock-frequency, remove the right-shifting hack (which was needed due to
reading a 32 bit value into a 64 bit variable) and switch to OF_getencprop()
for reading (which will handle endian conversion internally.)

There are a couple of places in the tree that directly parse the newvers.sh
script looking for the BRANCH variable. I found two locations, one in
release/Makefile and the other in bin/freebsd-version/Makefile.
While there is a good argument that BRANCH_OVERRIDE should properly
propagate in those circumstances and the new behavior is thus better, the
reality is this change broke freebsd-update's ability to find timestamps in
binaries and resulted in a large number of gratuitous changes.

Add enough infrastructure for interrupts on children of the pl061 GPIO
controller. As gpiobus already provided these the pl061 driver also needs
to pass requests up the newbus hierarchy.
Currently there are no children that expect to configure interrupts, however
this is expected to change to support the ACPI Event Information interface.

I have been trying to reduce the time that testsuite runs take for CheriBSD
on QEMU (currently about 22 hours). One of the slowest tests is pfctl_test:
Just listing the available test cases currently takes 98 seconds on a
CheriBSD RISC-V system due to all the processes being spawned. This trivial
patch reduces the time to 92 seconds. The better solution would be to
rewrite the test in C/C++ which I may do as a follow-up change.

common code out of arch-specific implementations. Move the mpr and mps
drivers to this new API. The template type remains visible to the consumer
so that it can be allocated on the stack, but should be considered opaque.
The change in D26397 will need a __FreeBSD_version to base off of for

where the panic message was "docallb", which indicates that a callback
was attempted when the ClientID is unconfirmed.
This would not normally occur, but it is possible to have an unconfirmed
ClientID structure with delegation structure(s) chained off it if the
client were to issue a SetClientID with the same "id" but different
"verifier" after acquiring delegations on the previously confirmed ClientID.
The bug appears to be that nfsrv_checkgetattr() failed to check for
this uncommon case of an unconfirmed ClientID with a delegation structure
that no longer refers to a delegation the client knows about.
This patch adds a check for this case, handling it as if no delegation
exists, which is the case when the above occurs.
Although difficult to reproduce, this change should avoid the panic().

The intention of the bus_be naming was for those to be the no-endian-swapping
and for the bus_le to be endian-swapping in all the functions.
This naming breaks down when we're actually are running in LE and need to
use the opposite sense.
As such, rename bs_be_* to native_bs_* and rename bs_le_* to swapped_bs_*.

Prior to this commit, EC2 AMIs used a "dual-dhclient" tool which was
launched in place of dhclient and spawned both the base system dhclient
for IPv4 and the ISC dhclient from ports for IPv6.
Now that rtsold supports the "M bit" (managed configuration), we can go
back to having the base system dhclient spawned normally, and provide a
script to rtsold which spawns the ISC dhclient from ports when rtsold
decides that it is appropriate.

The FreeBSD base system continues to expand. 4GB is now insufficient;
we passed 3 GB in May 2019; we passed 2 GB in August 2017. Over half

Without this change, instances boot but are unusable, since the first
thing which breaks when VM filesystems are too small is the "pkg install"

The floppy test passes with this. The others fail due to 'integrity
checks' failing in GPART. It's not at all clear those integrity
checks are legit or if the test samples were bogusly generated
by FreeBSD.
For configurations without x2APIC support (guests, older hardware), the global
LAPIC MMIO mapping will trigger false-positive KCSan reports as it will appear
that multiple CPUs are concurrently reading and writing the same address.
This isn't actually true, as the underlying physical access will be performed
on the local CPU's APIC. Additionally, because LAPIC access can happen during
event timer configuration, the resulting KCSan printf can produce a panic due
to attempted recursion on event timer resources.
Add a __nosanitizethread preprocessor define to prevent the compiler from
inserting TSan hooks, and apply it to the x86 LAPIC accessors.
