3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ben Hutchings <[email protected]> commit 9ec84acee1e221d99dc33237bff5e82839d10cc0 upstream. We do want to allow lock debugging for GPL-compatible modules that are not (yet) built in-tree. This was disabled as a side-effect of commit 2449b8ba0745327c5fa49a8d9acffe03b2eded69 ('module,bug: Add TAINT_OOT_MODULE flag for modules not built in-tree'). Lock debug warnings now include taint flags, so kernel developers should still be able to deflect warnings caused by out-of-tree modules. The TAINT_PROPRIETARY_MODULE flag for non-GPL-compatible modules will still disable lock debugging.
