Pull ARM SoC fixes from Olof Johansson:
 "Much smaller batch of fixes this week.

  Biggest one is a revert of an OMAP display change that removed some
  non-DT pinmux code that was still needed for 3.13 to get DSI displays
  to work.

  There's also a fix that resolves some misdescribed GPIO controller
  resources on shmobile.  The rest are mostly smaller fixes, a couple of
  MAINTAINERS updates, etc"

 "Mostly minor items this time around, the most notable being a FILEIO
  backend change to enforce hw_max_sectors based upon the current
  block_size to address a bug where large sized I/Os (> 1M) where being
  rejected"

  target: Remove write-only stats fields and lock from struct se_node_acl
  iscsi-target: return -EINVAL on oversized configfs parameter

Some pstore backing devices use on board flash as persistent
storage. These have limited numbers of write cycles so it
is a poor idea to use them from high frequency operations.

From Simon Horman:
Renesas ARM based SoC fixes for v3.13

* r8a7790 (R-Car H1) SoC
  - Correct GPIO resources in DT.

    This problem has been present since GPIOs were added to the r8a7790 SoC
    by f98e10c88aa95bf7 ("ARM: shmobile: r8a7790: Add GPIO controller
    devices to device tree") in v3.12-rc1.

* irqchip renesas-intc-irqpin
  - Correct register bitfield shift calculation

    This bug has been present since the renesas-intc-irqpin driver was
    introduced by 443580486e3b9657 ("irqchip: Renesas INTC External IRQ pin
    driver") in v3.10-rc1

* Lager board
  - Do not build the phy fixup unless CONFIG_PHYLIB is enabled

    This problem was introduced by 48c8b96f21817aad

* tag 'renesas-fixes-for-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: r8a7790: Fix GPIO resources in DTS

Pull Xen bugfixes from Konrad Rzeszutek Wilk:
 - Fix balloon driver for auto-translate guests (PVHVM, ARM) to not use
   scratch pages.
 - Fix block API header for ARM32 and ARM64 to have proper layout
 - On ARM when mapping guests, stick on PTE_SPECIAL
 - When using SWIOTLB under ARM, don't call swiotlb functions twice
 - When unmapping guests memory and if we fail, don't return pages which
   failed to be unmapped.
 - Grant driver was using the wrong address on ARM.

* tag 'stable/for-linus-3.13-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
  xen/balloon: Seperate the auto-translate logic properly (v2)
  xen/block: Correctly define structures in public headers on ARM32 and ARM64
  arm: xen: foreign mapping PTEs are special.
  xen/arm64: do not call the swiotlb functions twice
  xen: privcmd: do not return pages which we have failed to unmap
  XEN: Grant table address, xen_hvm_resume_frames, is a phys_addr not a pfn

This patch fixes a possible scsi_host reference leak in qlt_lport_register(),
when a non zero return from the passed (*callback) does not call drop the
local reference via scsi_host_put() before returning.

This currently does not effect existing tcm_qla2xxx code as the passed callback
will never fail, but fix this up regardless for future code.

lun->lun_ref is also initialized in core_tpg_post_addlun, so it doesn't
need to be done in core_tpg_setup_virtual_lun0.

This patch allows FILEIO to update hw_max_sectors based on the current
max_bytes_per_io.  This is required because vfs_[writev,readv]() can accept
a maximum of 2048 iovecs per call, so the enforced hw_max_sectors really
needs to be calculated based on block_size.

This addresses a >= v3.5 bug where block_size=512 was rejecting > 1M
sized I/O requests, because FD_MAX_SECTORS was hardcoded to 2048 for
the block_size=4096 case.

(v2: Use max_bytes_per_io instead of ->update_hw_max_sectors)
