arm/arm64: Share memregions

arm/arm64 (and to a small extent powerpc) have memory regions which
get built from hardware descriptions (DT/ACPI/EFI) and then used to
build page tables. Move memregions to common code, tweaking the API
a bit at the same time, e.g. change 'mem_region' to 'memregions'.
The biggest change is there is now a default number of memory regions
which, if too small, should be overridden at setup time with a new
init function, memregions_init().

arm/arm64: setup: Consolidate memory layout assumptions

Keep as much memory layout assumptions as possible in init::start
and a single setup function. This prepares us for calling setup()
from different start functions which have been linked with different
linker scripts. To do this, stacktop is only referenced from
init::start, making freemem_start a parameter to setup(). We also
split mem_init() into three parts, one that populates the mem regions
per the DT, one that populates the mem regions per assumptions,
and one that does the mem init. The concept of a primary region
is dropped, but we add a sanity check for the absence of memory
holes, because we don't know how to deal with them yet.

arm/arm64: mmu: Remove memory layout assumptions

Rather than making too many assumptions about the memory layout
in mmu code, just set up the page tables per the memory regions
(which means putting all the memory layout assumptions in setup).
To ensure we get the right default flags set we need to split the
primary region into two regions for code and data.

We still only expect the primary regions to be present, but the
next patch will remove that assumption too.

(Unfortunately we still have an assumption in setup_mmu. We assume
the range 3G-4G is available for the virtual memory allocator. We'll
need to remove that assumption as well with another patch in order
to support arbitrary memory maps.)

arm/arm64: fix gic-ipi test regression

The gic-ipi tests started crashing in a strange way after
commit 9064d89b ("kvm-unit-tests: unlock before calling

being the problem. I still don't understand what's going on,
but NR_CPUS=511 works and NR_CPUS=512 doesn't. I don't have
time to debug this further right now, so this is just a
temporary hack that appears to fix the regression.

Merge branch 'ppc64/initial-drop-v7' of https://github.com/rhdrjones/kvm-unit-tests into HEAD

This series brings basic setup; starts a test's C entry point, main(),
and printf, exit, and malloc work. Three more series should follow this
one which must bring; vector support, mmu support, and smp support, at
which point I believe the framework could just evolve with the creation
of unit tests.

Tested on TCG and a P8 kvm_pr machine, and Laurent has tested it on
both a PowerMac G5 (kvm_pr) and a kvm_hv machine. I'm looking forward
to hearing more testing feedback from others though.
