+Subject: lockdep, bug: Exclude TAINT_FIRMWARE_WORKAROUND from disabling lockdep
+
+From: Peter Zijlstra <a.p.zijlstra@chello.nl>
+
+commit df754e6af2f237a6c020c0daff55a1a609338e31 upstream.
+
+It's unlikely that TAINT_FIRMWARE_WORKAROUND causes false
+lockdep messages, so do not disable lockdep in that case.
+We still want to keep lockdep disabled in the
+TAINT_OOT_MODULE case:
+
+ - bin-only modules can cause various instabilities in
+ their and in unrelated kernel code
+
+ - they are impossible to debug for kernel developers
+
+ - they also typically do not have the copyright license
+ permission to link to the GPL-ed lockdep code.

+Subject: lockdep, bug: Exclude TAINT_OOT_MODULE from disabling lock debugging
+
+From: Ben Hutchings <ben@decadent.org.uk>
+
+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.
