Hi Steven,
Today's linux-next merge of the ftrace tree got a conflict in
kernel/panic.c between commit dcb6b45254e2 ("panic: add cpu/pid to
warn_slowpath_common in WARNING printk()s") from the tree and commit
de7edd31457b ("tracing: Disable tracing on warning") from the ftrace tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
