This series provides KVM selftests that test dirty log tracking on
AArch64 for both 4K and 64K guest page sizes. Additionally the
framework provides an easy way to test dirty log tracking with the
recently posted dynamic IPA and 52bit IPA series[1].
The series breaks down into parts as follows:
01-02: generalize guest code to host userspace exit support by
introducing "ucalls" - hypercalls to userspace
03-05: prepare common code for a new architecture
06-07: add virtual memory setup support for AArch64
08: add vcpu setup support for AArch64
09: port the dirty log test to AArch64
10-11: add 64K guest page size support for the dirty log test
12-13: prepare the dirty log test to also test > 40-bit guest
physical address setups by allowing the test memory
region to be placed at the top of physical memory
