This series is made out of three logical parts - patches 1 and 2 fix panic caused by accessing freed module memory - patches 3 and 4 fix miscounting by static_key_slow_dec_deferred() - patch 5 introduces a minor optimization More jump_label/static_key patches are prepared, but I returned to them yesterday and implemented a variable jump length on amd64, which requires some refactoring, porting to remaining architectures, and retesting, so I'm posting this independent part before it gets overtaken by higher priority work again => This series was tested with additional patches ^ I wrote this on Tuesday and then moved to higher priority work, but returned with enough courage to post a different first part. The first part was tested on amd64, s390x and ppc64, the rest also on armv7. Applies to next-20131206 and v3.13-rc3.
