That's a merge commit.  I'll rewrite this to 76ae847497bc52
("Documentation: raise minimum supported version of GCC to 5.1"). 
Which, although misnamed is the commit which made the change.

I'll make that f02c69680088 ("include/linux/memory.h: implement
register_hotmemory_notifier()").

And hot damn I write good changelogs!  Wrote :(

I redid the changelogs thusly:

: Commit 76ae847497bc52 ("Documentation: raise minimum supported version of
: GCC to 5.1") updated the minimum gcc version to 5.1.  So the problem
: mentioned in f02c69680088 ("include/linux/memory.h: implement
: register_hotmemory_notifier()") no longer exist.  So we can now switch to
: use hotplug_memory_notifier() directly rather than
: register_hotmemory_notifier().
