       "A regression fix, new unit test infrastructure and a build fix:
      
         - Regression fix addressing support for the new NVDIMM label storage
           area access commands (_LSI, _LSR, and _LSW).
      
           The Intel specific version of these commands communicated the
           "Device Locked" status on the label-storage-information command.
      
           However, these new commands (standardized in ACPI 6.2) communicate
           the "Device Locked" status on the label-storage-read command, and
           the driver was missing the indication.
      
           Reading from locked persistent memory is similar to reading
           unmapped PCI memory space, returns all 1's.
      
         - Unit test infrastructure is added to regression test the "Device
           Locked" detection failure.
      
         - A build fix is included to allow the "of_pmem" driver to be built
           as a module and translate an Open Firmware described device to its
           local numa node"

      afs: Fix server record deletion · 66062592
      David Howells authored
      AFS server records get removed from the net->fs_servers tree when
      they're deleted, but not from the net->fs_addresses{4,6} lists, which
      can lead to an oops in afs_find_server() when a server record has been
      removed, for instance during rmmod.
      
      Fix this by deleting the record from the by-address lists before posting
      it for RCU destruction.
      
      The reason this hasn't been noticed before is that the fileserver keeps
      probing the local cache manager, thereby keeping the service record
      alive, so the oops would only happen when a fileserver eventually gets
      bored and stops pinging or if the module gets rmmod'd and a call comes
      in from the fileserver during the window between the server records
      being destroyed and the socket being closed.
      
      The oops looks something like:
      
        BUG: unable to handle kernel NULL pointer dereference at 000000000000001c
        ...
        Workqueue: kafsd afs_process_async_call [kafs]
