Subjectlinux-next: manual merge of the tile tree with Linus' tree
Hi Chris,

Today's linux-next merge of the tile tree got a conflict in
arch/tile/include/asm/barrier.h (actually setup.h - git tried its best)
between commit bd119c692393 ("Disintegrate asm/system.h for Tile") from
Linus' tree and commit 8507ce994794 ("arch/tile: fix hardwall for tilegx
and generalize for idn and ipi") from the tile tree.

I used the upstream version of barrier.h and applied the following merge

It may be worth while rebasing the tile tree on top of v3.4-rc1 or
(maybe better) merging 3.4-rc1 into the tile tree.
