linux-next: manual merge of the rr tree with the ftrace tree

[Stephen Rothwell <sfr@canb.auug.org.au>]

Hi Rusty,

Today's linux-next merge of the rr tree got a conflict in kernel/module.c
between commit 3861a17bcc0af815f684c6178bc9ec2d790c350e
("tracing/function-graph-tracer: drop the kernel_text_address check")
from the ftrace tree and commit 820936d2f463760545e8ef2ae2cd09d92605c69e
("module:module_address") from the rr tree.

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