[GIT PULL] target fixes for v3.9-rc7

[GIT PULL] target fixes for v3.9-rc7

[Nicholas A. Bellinger]

Hello Linus,

Here are remaining target-pending items for v3.9-rc7 code.

Please go ahead and pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master

The tcm_vhost patches are more than I'd usually include in a -rc7 PULL,
but are changes required for v3.9 to work correctly with the pending
vhost-scsi-pci QEMU upstream series merge.  (Paolo CC'ed)

Plus Asias's conversion to use vhost_virtqueue->private_data + RCU for
managing vhost-scsi endpoints has gotten alot of review + testing over
the past weeks, and MST has ACKed the full series.

Also, there is a target patch to fix a long-standing bug within control
CDB handling with Standby/Offline/Transition ALUA port access states,
that had been incorrectly rejecting the control CDBs required for LUN
scan to work during these port group states.  CC'ing to stable.

Thank you,

--nab
