Subject: linux-next: manual merge of the kvm-arm tree with the kvm tree

Hi all,

Today's linux-next merge of the kvm-arm tree got a conflict in:

  tools/testing/selftests/kvm/aarch64/vgic_init.c

between commits:

  98f94ce42ac6 ("KVM: selftests: Move KVM_CREATE_DEVICE_TEST code to separate helper")
  7ed397d107d4 ("KVM: selftests: Add TEST_REQUIRE macros to reduce skipping copy+paste")

from the kvm tree and commit:

  6a4f7fcd7504 ("KVM: arm64: selftests: Add support for GICv2 on v3")

from the kvm-arm tree.

I fixed it up (I think, see below) and can carry the fix as
necessary. This is now fixed as far as linux-next is concerned, but any
non trivial conflicts should be mentioned to your upstream maintainer
when your tree is submitted for merging.  You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.
