Hi Paul,
Today's linux-next merge of the kvm-ppc tree got conflicts in:
arch/powerpc/include/asm/opal.h
arch/powerpc/platforms/powernv/opal-wrappers.S
between commit:
1d0761d2557d ("powerpc/powernv: Initialise nest mmu")
from the powerpc tree and commit:
ab9bad0ead9a ("powerpc/powernv: Remove separate entry for OPAL real mode calls")
from the kvm-ppc 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.

Thanks.
This will go away when I merge the ppc-kvm topic branch.

Hi Alexander,
Today's linux-next merge of the kvm-ppc tree got a conflict in
arch/powerpc/kvm/booke_interrupts.S between commit c75df6f96c59
("powerpc: Fix usage of register macros getting ready for %r0 change")
from the powerpc tree and commit fc372c0843b8 ("booke: Added crit/mc
exception handler for e500v2") from the kvm-ppc tree.
I fixed it up (see below - could do with checking) and can carry the fix
as necessary.

Hrm. Ben already warned me that this will happen, so I did a test merge a few days ago. Back then I also had to change 2 other bits that were not conflicting, to get to code to actually compile.
Could you please do an s/VCPU_GPR(r/VCPU_GPR/R/g in arch/powerpc/kvm/booke_interrupts.S? I'd check if you actually need it myself, but the tree doesn't seem to be pushed out yet :).

Thanks for the response. I checked and I think I got them all. The
tree should be available as soon as the kernel.org mirroring gets done.
