4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Brian Starkey <[email protected]> [ Upstream commit 7916efe5b57505080b3cebf5bdb228b4eda008ea ] The horizontal and vertical flip flags were the wrong way around, causing reflect-x to result in reflect-y being applied and vice-versa. Fix them.
