Subject: linux-next: manual merge of the kvm-ppc-paulus tree with the
 powerpc-fixes tree

Hi Paul,

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

  arch/powerpc/include/asm/asm-prototypes.h

between commit:

  9e5f68842276 ("powerpc: Fix missing CRCs, add more asm-prototypes.h declarations")

from the powerpc-fixes tree and commit:

  ebe4535fbe7a ("KVM: PPC: Book3S HV: sparse: prototypes for functions called from assembler")

from the kvm-ppc-paulus 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
