Pull firewire updates from Takashi Sakamoto:
 "This update replaces the remaining tasklet usage in the FireWire
  subsystem with workqueue for asynchronous packet transmission. With
  this change, tasklets are now fully eliminated from the subsystem.

  Asynchronous packet transmission is used for serial bus topology
  management as well as for the operation of the SBP-2 protocol driver
  (firewire-sbp2). To ensure reliability during low-memory conditions,
  the associated workqueue is created with the WQ_MEM_RECLAIM flag,
  allowing it to participate in memory reclaim paths. Other attributes
  are aligned with those used for isochronous packet handling, which was
  migrated to workqueues in v6.12.

  The workqueues are sleepable and support preemptible work items,
  making them more suitable for real-time workloads that benefit from
  timely task preemption at the system level.

  There remains an issue where 'schedule()' may be called within an RCU
  read-side critical section, due to a direct replacement of
  'tasklet_disable_in_atomic()' with 'disable_work_sync()'. A proposed
  fix for this has been posted[1], and is currently under review and
  testing. It is expected to be sent upstream later"
