Subject: linux-next: build failure after merge of the scsi tree

Hi James,

After merging the scsi tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/scsi/qedi/qedi_main.c: In function 'qedi_init':
drivers/scsi/qedi/qedi_main.c:2073:2: error: implicit declaration of function 'register_hotcpu_notifier' [-Werror=implicit-function-declaration]
  register_hotcpu_notifier(&qedi_cpu_notifier);
  ^
drivers/scsi/qedi/qedi_main.c: In function 'qedi_cleanup':
drivers/scsi/qedi/qedi_main.c:2113:2: error: implicit declaration of function 'unregister_hotcpu_notifier' [-Werror=implicit-function-declaration]
  unregister_hotcpu_notifier(&qedi_cpu_notifier);
  ^

Caused by commit

  ace7f46ba5fd ("scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework.")

Interacting with commit

  8e38db753d95 ("cpu/hotplug: Remove obsolete cpu hotplug register/unregister functions")

from the tip tree.

I have disabled that driver for now:

Subject: [PATCH] scsi: disable the QEDI driver for now

until it can be converted to cope with the removal of
register_hotcpu_notifier.
