Subject: linux-next: manual merge of the xen-tip tree with the tip tree

Hi all,

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

  arch/x86/xen/smp.c

between commit:

  4c9075835511 ("xen/x86: Move irq allocation from Xen smp_op.cpu_up()")

from the tip tree and commit:

  ad5475f9faf5 ("x86/xen: use xen_vcpu_id mapping for HYPERVISOR_vcpu_op")

from the xen-tip 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.

Cheers,
Stephen Rothwell
