Linus Torvalds 0375ec5899 SCSI misc on 20130915
This patch set is a set of driver updates (megaraid_sas, fnic, lpfc, ufs,
 hpsa) we also have a couple of bug fixes (sd out of bounds and ibmvfc error
 handling) and the first round of esas2r checker fixes and finally the much
 anticipated big endian additions for megaraid_sas.

Linus Torvalds 48efe453e6 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "Lots of activity again this round for I/O performance optimizations
  (per-cpu IDA pre-allocation for vhost + iscsi/target), and the
  addition of new fabric independent features to target-core
  (COMPARE_AND_WRITE + EXTENDED_COPY).

  The main highlights include:

   - Support for iscsi-target login multiplexing across individual
     network portals
   - Generic Per-cpu IDA logic (kent + akpm + clameter)
   - Conversion of vhost to use per-cpu IDA pre-allocation for
     descriptors, SGLs and userspace page pointer list
   - Conversion of iscsi-target + iser-target to use per-cpu IDA
     pre-allocation for descriptors
   - Add support for generic COMPARE_AND_WRITE (AtomicTestandSet)
     emulation for virtual backend drivers
   - Add support for generic EXTENDED_COPY (CopyOffload) emulation for
     virtual backend drivers.
   - Add support for fast memory registration mode to iser-target (Vu)

  The patches to add COMPARE_AND_WRITE and EXTENDED_COPY support are of
  particular significance, which make us the first and only open source
  target to support the full set of VAAI primitives.

  Currently Linux clients are lacking upstream support to actually
  utilize these primitives.  However, with server side support now in
  place for folks like MKP + ZAB working on the client, this logic once
  reserved for the highest end of storage arrays, can now be run in VMs
  on their laptops"

Brian Uchino 87aa619c17 [SCSI] fnic: On system with >1.1TB RAM, VIC fails multipath after boot up
Issue was seen when SCSI buffer address is more than 40 bits in system
with more than 1.1TB RAM. When SCSI buffer is passed to VIC, it is failing
to map to correct buffer address, as DMA mask is set to 40 bits in driver
initialization. Corrected DMA_MASK from 40-bits to 64-bits to avoid masking
41-64 bits addresses.

This patch fixes an out-of-bounds error in sd_read_cache_type(), found
by Google's AddressSanitizer tool.  When the loop ends, we know that
"offset" lies beyond the end of the data in the buffer, so no Caching
mode page was found.  In theory it may be present, but the buffer size
is limited to 512 bytes.

Greg Kroah-Hartman 9807b4d949 [SCSI] Allow MPT Fusion SAS 3.0 driver to be built into the kernel
