Merge branch 'juju' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6

* 'juju' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6: (138 commits)
  firewire: Convert OHCI driver to use standard goto unwinding for error handling.
  firewire: Always use parens with sizeof.
  firewire: Drop single buffer request support.
  firewire: Add a comment to describe why we split the sg list.
  firewire: Return SCSI_MLQUEUE_HOST_BUSY for out of memory cases in queuecommand.
  firewire: Handle the last few DMA mapping error cases.
  firewire: Allocate scsi_host up front and allocate the sbp2_device as hostdata.
  firewire: Provide module aliase for backwards compatibility.
  firewire: Add to fw-core-y instead of assigning fw-core-objs in Makefile.
  firewire: Break out shared IEEE1394 constant to separate header file.
  firewire: Use linux/*.h instead of asm/*.h header files.
  firewire: Uppercase most macro names.
  firewire: Coding style cleanup: no spaces after function names.
  firewire: Convert card_rwsem to a regular mutex.
  firewire: Clean up comment style.
  firewire: Use lib/ implementation of CRC ITU-T.
  CRC ITU-T V.41
  firewire: Rename fw-device-cdev.c to fw-cdev.c and move header to include/linux.
  firewire: Future proof the iso ioctls by adding a handle for the iso context.
  firewire: Add read/write and size annotations to IOC numbers.
