Applied to devel/for-linus-3.18.

Thanks.

Your lines in your descriptions were too long for the default git log
format.  I fixed this up but can you ensure they're wrapped at 72
characters next time.  Also Xen isn't an abbreviation and should not be
capitalized.

[PATCH V6 0/5] Add XEN pvSCSI support

[Juergen Gross]

This series adds XEN pvSCSI support. With pvSCSI it is possible to use physical
SCSI devices from a XEN domain.

The support consists of a backend in the privileged Domain-0 doing the real
I/O and a frontend in the unprivileged domU passing I/O-requests to the backend.

The code is taken (and adapted) from the original pvSCSI implementation done
for Linux 2.6 in 2008 by Fujitsu.

Changes in V6:
- changes in scsifront module after comments from Konrad Wilk
- remove double kfree in scsiback
- comments in vscsiif.h adapted after comments from Jan Beulich and
  David Vrabel in xen-devel
- added linux-scsi@vger.kernel.org to MAINTANERS entry

Changes in V5:
- Added patch to support threaded irqs for interdomain event channels
- several changes in xen-scsifront after comments from Christoph Hellwig
- several changes in xen-scsiback after comments from Christoph Hellwig
- several changes in xen-scsiback after comments from James Bottomley
- several changes in xen-scsiback after comments from Nicholas Bellinger

Changes in V4:
- Re-add define for VSCSIIF_ACT_SCSI_SG_PRESET to vscsiif.h to indicate this
  action value should not be used in future enhancements

Changes in V3:
- added some comments to the protocol header file
- removed the CDB emulation from xen-scsiback, handled by core target
  infrastructure
- several changes in xen-scsifront after comments from Christoph Hellwig

Changes in V2:
- use core target infrastructure by backend instead of pure SCSI passthrough
- add support for larger SG lists by putting them in grant page(s)
- add command abort capability
