[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------


This reverts commit abdbd5f3e8c504d864fdc032dd5a4eb481cb12bf which is commit
91b80cc5b39f00399e8e2d17527cad2c7fa535e2 upstream.

   18 | #include "vm_util.h"
      |          ^~~~~~~~~~~
