Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx,
  hisi_sas, smartpqi, megaraid_sas, arcmsr.

  In addition, with the continuing absence of Nic we have target updates
  for tcmu and target core (all with reviews and acks).

  The biggest observable change is going to be that we're (again) trying
  to switch to mulitqueue as the default (a user can still override the
  setting on the kernel command line).

  Other major core stuff is the removal of the remaining Microchannel
  drivers, an update of the internal timers and some reworks of
  completion and result handling"

-/* Notes:
- *
- * Most of the work is done in the chip specific module, 53c700.o
- *
- * TODO List:
- *
- * 1. Extract the SCSI ID from the voyager CMOS table (necessary to
- *    support multi-host environments.
- *
- * */
-
-
-/* CHANGELOG 
- *
- * Version 2.2
- *
- * Added mca_set_adapter_name().
- *
- * Version 2.1
- *
- * Modularise the driver into a Board piece (this file) and a chip
- * piece 53c700.[ch] and 53c700.scr, added module options.  You can
- * now specify the scsi id by the parameters
- *
- * NCR_D700=slot:<n> [siop:<n>] id:<n> ....
- *
- * They need to be comma separated if compiled into the kernel
- *
- * Version 2.0
- *
- * Initial implementation of TCQ (Tag Command Queueing).  TCQ is full
- * featured and uses the clock algorithm to keep track of outstanding
- * tags and guard against individual tag starvation.  Also fixed a bug
- * in all of the 1.x versions where the D700_data_residue() function
- * was returning results off by 32 bytes (and thus causing the same 32
- * bytes to be written twice corrupting the data block).  It turns out
- * the 53c700 only has a 6 bit DBC and DFIFO registers not 7 bit ones
- * like the 53c710 (The 710 is the only data manual still available,
- * which I'd been using to program the 700).
- *
- * Version 1.2
- *
- * Much improved message handling engine
- *
- * Version 1.1
- *
- * Add code to handle selection reasonably correctly.  By the time we
- * get the selection interrupt, we've already responded, but drop off the
- * bus and hope the selector will go away.
- *
- * Version 1.0:
- *
- *   Initial release.  Fully functional except for procfs and tag
- * command queueing.  Has only been tested on cards with 53c700-66
- * chips and only single ended. Features are
- *
- * 1. Synchronous data transfers to offset 8 (limit of 700-66) and
- *    100ns (10MHz) limit of SCSI-2
- *
- * 2. Disconnection and reselection
- *
- * Testing:
- * 
- *  I've only really tested this with the 700-66 chip, but have done
- * soak tests in multi-device environments to verify that
- * disconnections and reselections are being processed correctly.
