[PATCH 0/7] KVM: selftests: Fix maxnodes bugs and cleanup related code

[Sean Christopherson]

This is a spin-off of Shivank's series[*] to fix "flaws" in KVM selftests
handling of @maxnode in various sycalls.  In quote because the flaw is that
KVM selftests followed the docs, and the kernel has a longstanding, poorly
documented off-by-one bug.

Along the way, massage the xAPIC IPI test to automatically run its page
migration testcases when possible, because that's the entire reason the
test exists.

I didn't included the guest_memfd changes that were the focus of Shivank's
series, as they are bigger and more involved (I'll let Shivank tackle those).
