linux-next: manual merge of the ftrace tree with Linus' tree

From: Stephen Rothwell

Hi Steven,

Today's linux-next merge of the ftrace tree got a conflict in:

kernel/events/uprobes.c

between commit:

788faab70d5a ("perf, tools: Use correct articles in comments")

from Linus' tree and commit:

38e967ae1e60 ("Uprobes: Simplify uprobe_register() body")

from the ftrace tree.

I fixed it up (the latter moved the uprobe_unregister function - see
below) and can carry the fix as necessary. This is now fixed as far as
linux-next is concerned, but any non trivial conflicts should be mentioned
to your upstream maintainer when your tree is submitted for merging.
You may also want to consider cooperating with the maintainer of the
conflicting tree to minimise any particularly complex conflicts.
