0c60fa8268 net_util: tests: Avoid trying to create TAP devices simultaneously
The unit tests ask the Linux kernel to generate a TAP device name on
demand by passing in a format string. I suspect, but haven't been able
to confirm that there might be a rare race that triggers when creating
lots of devices in a short period of time. This is appearing in our unit
test as the occassional flake of the test_tap_read() which although it
has successfully created the device it fails to set the IP address on it
when looking it back up by it's name.

Since this is the most frequent cause of failures on our CI use a lock
to ensure that multiple TAP devices are not created simultaneously.

Fixes: #2135

76e15a4240 vmm: acpi: Support compiling ACPI code on aarch64
This skeleton commit brings in the support for compiling aarch64 with
the "acpi" feature ready to the ACPI enabling. It builds on the work to
move the ACPI hotplug devices from I/O ports to MMIO and conditionalises
any code that is x86_64 only (i.e. because it uses an I/O port.)

Filling in the aarch64 specific details in tables such as the MADT it
out of the scope.

See: #2178
