Subject: [PATCH 4.9 062/177] openrisc: fix issue handling 8 byte get_user calls

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

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

From: Stafford Horne <shorne@...il.com>


[ Upstream commit 154e67cd8e8f964809d0e75e44bb121b169c75b3 ]

Was getting the following error with allmodconfig:

  ERROR: "__get_user_bad" [lib/test_user_copy.ko] undefined!

This was simply a missing break statement, causing an unwanted fall
through.
