Linus Torvalds 467a9e1633 CPU hotplug notifiers registration fixes for 3.15-rc1 ... The purpose of this single series of commits from Srivatsa S Bhat (with a small piece from Gautham R Shenoy) touching multiple subsystems that use CPU hotplug notifiers is to provide a way to register them that will not lead to deadlocks with CPU online/offline operations as described in the changelog of commit 93ae4f978c (CPU hotplug: Provide lockless versions of callback registration functions). The first three commits in the series introduce the API and document it and the rest simply goes through the users of CPU hotplug notifiers and converts them to using the new method. / -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJTQow2AAoJEILEb/54YlRxW4QQAJlYRDUzwFJzJzYhltQYuVR+ 4D74XMtvXgoJfg3cwdSWvMKKpJZnA9BVN0f7Hcx9wYmgdexYUuHeZJmMNyc3S2+g KjKBIsugvgmZhHbbLd6TJ6GBbhGT5JLt9VmSfL9zIkveInU1YHFUUqL/mxdHm4J0 BSGKjk2rN3waRJgmY+xfliFLtQjDKFwJpMuvrgtoUyfas3f4sIV43UNbqdvA/weJ rzedxXOlKH/id4b56lj/4iIzcoL3mwvJJ7r6n0CEMsKv87z09kqR0O+69Tsq/cgs j17CsvoJOmZGk3QTeKVMQWBsvk6aPoDu3zK83gLbQMt+qjOpSTbJLz/3HZw4/TrW ss4nuZne1DLMGS+6hoxYbTP+6Ni//Kn+l/LrHc5jb7m1X3lMO4W2aV3IROtIE1rv lEP1IG01NU4u9YwkVj1dyhrkSp8tLPul4SrUK8W+oNweOC5crjJV7vJbIPJgmYiM IZN55wln0yVRtR4TX+rmvN0PixsInE8MeaVCmReApyF9pdzul/StxlBze5BKLSJD cqo1kNPpsmdxoDucqUpQ/gSvy+IOl2qnlisB5PpV93sk7De6TFDYrGHxjYIW7jMf StXwdCDDQhzd2Q8Kfpp895A1dbIl8rKtwA6bTU2eX+BfMVFzuMdT44cvosx1+UdQ sWl//rg76nb13dFjvF+q =SW7Q -----END PGP SIGNATURE----- Merge tag 'cpu-hotplug-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull CPU hotplug notifiers registration fixes from Rafael Wysocki: "The purpose of this single series of commits from Srivatsa S Bhat (with a small piece from Gautham R Shenoy) touching multiple subsystems that use CPU hotplug notifiers is to provide a way to register them that will not lead to deadlocks with CPU online/offline operations as described in the changelog of commit 93ae4f978c ("CPU hotplug: Provide lockless versions of callback registration functions").
