Ha! I was wondering how my old @intel address snuck in...

On the aarch64 side, with the following tweaks, courtesy of Raghu, all tests
pass. I'll work these into the next version, and hopefully also learn how to
run on aarch64 myself...

Note, the i => 0 "fix" in test_v3_typer_accesses() is a direct revert of patch 3,
"KVM: selftests: Fix typo in vgic_init test". I'll just drop that patch unless
someone figures out why doing the right thing causes the test to fail.
