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/enlighten.c

between commit:

687d77a5f7b2 ("x86/xen: Update e820 table handling to the new core x86 E820 code")

from the tip tree and commit:

ca7b75377014 ("x86/xen: split off enlighten_pvh.c")

from the xen-tip tree.

The latter moved the code changed by the former to another file, so I
have applied the following merge fix patch.

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.
