Merge branch 'tipc'

Jon Maloy says:

====================
Some small and relatively straightforward patches. With exception of
the two first ones they are all unrelated and address minor issues.

v2: update of v1 (http://patchwork.ozlabs.org/patch/277404/)

-added commit to use memcpy_fromiovec on user data as per v1 feedback
-updated sparse fix commit to drop chunks covered by above commit
-added new commit that greatly simplifies the link lookup routine
====================
