Subject: linux-next: manual merge of the borntraeger tree with the kvms390
 tree

Hi Christian,

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

  arch/s390/kvm/kvm-s390.c

between commit:

  be7c9d7ba9e4 ("KVM: s390: Populate mask of non-hypervisor managed facility bits")

from the kvms390 tree and commit:

  5c14ad932491 ("KVM: halt_polling: provide a way to qualify wakeups during poll")

from the borntraeger 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
