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/include/asm/traps.h

between commit:

  11a7ffb01703 ("x86/traps: Simplify pagefault tracing logic")

from the tip tree and commit:

  ad5b8c4ba323 ("xen: get rid of paravirt op adjust_exception_frame")

from the xen-tip 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
