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/include/x86_64/processor.h

between commit:

  ef6a74b2e55e ("KVM: sefltests: Add x86-64 test to verify MMU reacts to CPUID updates")

from the kvm tree and commit:

  75275d7fbef4 ("KVM: selftests: Introduce UCALL_UNHANDLED for unhandled vector reporting")

from the kvm-arm tree.

I fixed it up (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.

Cheers,
Stephen Rothwell
