Subject: linux-next: manual merge of the akpm-current tree with the ftrace
 tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
kernel/printk/printk.c between commit afdc34a3d3b8 ("printk: Add
per_cpu printk func to allow printk to be diverted") from the ftrace
tree and commit b59ed413b21b ("printk: add and use LOGLEVEL_<level>
defines for KERN_<LEVEL> equivalents") from the akpm-current tree.

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

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