Subject: [PATCH 0/1] selftests: kvm: Overlapped memory regions test

This introduces a test case to check memory slots with overlapped
regions on the guest address cannot be added. The cases checked
are described in the block comment upon test_overlap_memory_regions()
(see the patch 01).

I didn't see the need to calcute the addresses on compile/run-time, so I
just left them hard-coded (remember: aligned 1M to work on s390x).

It works on x86_64, aarch64, and s390x.

The patch is based on queue branch.

Ah, I did some cosmetic changes on test_add_max_memory_regions() too. If
it is not OK to be in a single patch...let me know.
