4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Eric Farman <[email protected]> commit 24abf2901b18bf941b9f21ea2ce5791f61097ae4 upstream. We have two nested loops to check the entries within the pfn_array_table arrays. But we mistakenly use the outer array as an index in our check, and completely ignore the indexing performed by the inner loop.
