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

Hi all,

Today's linux-next merge of the tip tree got a conflict in
arch/xtensa/include/asm/barrier.h between commit dbacef090841 ("xtensa:
add SMP support") from the xtensa tree and commit 93ea02bb8435 ("arch:
Clean up asm/barrier.h implementations using asm-generic/barrier.h") from
the tip tree.

I fixed it up (I am pretty sure - see below) and can carry the fix as
necessary (no action is required).

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
