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).
