[PATCH 00/13] kvm: selftests: add aarch64 framework and dirty

[Andrew Jones <drjones@redhat.com>]

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
