Hi Haibo,

This series needs a rebase on top of these recent patches

 commit ee053e03b08e ("KVM: selftests: get-reg-list: support ID register features")
 commit 5f0419a0083b ("KVM: selftests: get-reg-list: add Permission Indirection registers")

The conflicts will be in my patches, which do the splitting of the test.
I'll do the rebase and push it to a branch for you to pick up.

Thanks,
drew
