X-Git-Tag: firefly_0821_release~12455^2~4 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cdae0ad5e8ea630017d4cad3923f763c4e6c3127;p=firefly-linux-kernel-4.4.55.git lguest: move panic notifier registration to its expected place. We used to defer it, so lockdep was happy. We now init lockdep early anyway, so just do it after that.
