Subject: linux-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/kernel/single_step.c between commit cdd8e16feba8 ("arch/tile:
return SIGBUS for addresses that are unaligned AND invalid") from Linus'
tree and commit 25c5acbdcc06 ("arch/tile: support building big-endian
kernel") from the tile tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.

Cheers,
