[GIT PULL] target updates for v3.14-rc1

[Nicholas A. Bellinger]

Hi Linus!

Here are the target-pending updates for the v3.14-rc1 merge window.

Please pull from:

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

The highlights this round include:

  - Add support for SCSI Referrals (Hannes)
  - Add support for T10 DIF into target core (nab + mkp)
  - Add support for T10 DIF emulation in FILEIO + RAMDISK backends (Sagi + nab)
  - Add support for T10 DIF -> bio_integrity passthrough in IBLOCK backend (nab)
  - Prep changes to iser-target for >= v3.15 T10 DIF support (Sagi)
  - Add support for qla2xxx N_Port ID Virtualization - NPIV (Saurav + Quinn)
  - Allow percpu_ida_alloc() to receive task state bitmask (Kent)
  - Fix >= v3.12 iscsi-target session reset hung task regression (nab)
  - Fix >= v3.13 percpu_ref se_lun->lun_ref_active race (nab)
  - Fix a long-standing network portal creation race (Andy)

Just a heads up that you'll encounter two merge conflicts in
target_core_tpg.c + qla_target.c due to upstream v3.13 bugfixes.  The
resolutions are straightforward enough, but please yell if something
doesn't look right.

Also, Stephen is carrying one extra target_core_iblock.c patch to
address the immutable bio_vec changes that are currently outstanding in
Jens block PULL request.  That patch is here:
