For OMAP devices, if a gpio is being used as an interrupt source but has
not been requested by calling gpio_request(), a call to request_irq()
may cause the kernel hang because the gpio bank may be disabled and
hence the register access will fail. To prevent such hangs, test for
this case and warn if this is detected.

Currently the OMAP GPIO driver uses a legacy mapping for the GPIO IRQ
domain. This is not necessary because we do not need to assign a
specific interrupt number to the GPIO IRQ domain. Therefore, convert
the OMAP GPIO driver to use a linear mapping instead.

Please note that this also allows to simplify the logic in the OMAP
gpio_irq_handler() routine, by using irq_find_mapping() to obtain the
virtual irq number from the GPIO bank and bank index.

   - fix edac when it is loaded builtin (early init for the subsystem);
   - a "Firmware First" EDAC driver, allowing ghes to report errors via
     EDAC (ghes-edac).

  With regards to ghes-edac, this fixes a longstanding BZ at Red Hat
  that happens with Nehalem and Sandy Bridge CPUs: when both GHES and
  i7core_edac or sb_edac are running, the error reports are
  unpredictable, as both BIOS and OS race to access the registers.  With
  ghes-edac, the EDAC core will refuse to register any other concurrent
  memory error driver.

  This patchset moves the ghes struct definitions to a separate header
  file (include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to
  register/unregister and to report errors via ghes-edac.  Those changes
  were acked by ghes driver maintainer (Huang)."

The new intel_powerclamp thermal cooling device driver was merged in
commit 2af78448 (Pull thermal management updates from Zhang Rui)
without any data conflicts.  But there was a more subtle conflict I
missed: the driver uses MAX_USER_RT_PRIO, but commit 8bd75c77
("sched/rt: Move rt specific bits into new header file") had moved that
define from <linux/sched.h> to <linux/sched/rt.h>.

Which caused this build failure:

  drivers/thermal/intel_powerclamp.c: In function ‘clamp_thread’:
  drivers/thermal/intel_powerclamp.c:360:21: error: ‘MAX_USER_RT_PRIO’ undeclared (first use in this function)
  drivers/thermal/intel_powerclamp.c:360:21: note: each undeclared identifier is reported only once for each function it appears in

And because I don't do a full "make allmodconfig" build after each pull,
I didn't notice until too late.  So now the fix is here, separately from
the merge commit.

Pull ARM SoC mvebu platform changes from Olof Johansson:
 "This series contains changes for the Marvell EBU platforms (mvebu,
  orion, kirkwood, dove) that were not part of the first set of pull
  requests because of dependencies on the MMC tree, and being submitted
  a little late.

  Notable changes are:

   - More devices get moved out of board files into device tree
     descriptions.  The remaining devices listed in there have patches
     that will get sent for 3.10, after which we can remove a lot of the
     board files entirely.  We are doing the pinctrl and mmc drivers
     here, ethernet and PCI still remain.

   - SMP support for mvebu is improved with support for the local
     interrupt controller.

   - The Guruplug board file gets replaced with a DT description.

  Unfortunately, the dependency on the MMC tree turned out to be a much
  larger problem than expected, when the MMC maintainer rebased the
  patches in his tree that all of the patches in this branch are based
  on, which caused merge conflicts between the new and old versions of
  those patches.

  To work around the merge conflicts, this branch rebases all patches on
  top of the respective MMC patches that did get merged into 3.9.  The
  patches are all identical to the versions that were part of
  linux-next, but have a new commit date."

Pull Ceph updates from Sage Weil:
 "A few groups of patches here.  Alex has been hard at work improving
  the RBD code, layout groundwork for understanding the new formats and
  doing layering.  Most of the infrastructure is now in place for the
  final bits that will come with the next window.

  There are a few changes to the data layout.  Jim Schutt's patch fixes
  some non-ideal CRUSH behavior, and a set of patches from me updates
  the client to speak a newer version of the protocol and implement an
  improved hashing strategy across storage nodes (when the server side
  supports it too).

  A pair of patches from Sam Lang fix the atomicity of open+create
  operations.  Several patches from Yan, Zheng fix various mds/client
  issues that turned up during multi-mds torture tests.

  A final set of patches expose file layouts via virtual xattrs, and
  allow the policies to be set on directories via xattrs as well
  (avoiding the awkward ioctl interface and providing a consistent
  interface for both kernel mount and ceph-fuse users)."

Pull writeback fixes from Wu Fengguang:
 "Two writeback fixes

   - fix negative (setpoint - dirty) in 32bit archs

   - use down_read_trylock() in writeback_inodes_sb(_nr)_if_idle()"

Pull block driver bits from Jens Axboe:
 "After the block IO core bits are in, please grab the driver updates
  from below as well.  It contains:

   - Fix ancient regression in dac960.  Nobody must be using that
     anymore...

   - Some good fixes from Guo Ghao for loop, fixing both potential
     oopses and deadlocks.

   - Improve mtip32xx for NUMA systems, by being a bit more clever in
     distributing work.

   - Add IBM RamSan 70/80 driver.  A second round of fixes for that is
     pending, that will come in through for-linus during the 3.9 cycle
     as per usual.

   - A few xen-blk{back,front} fixes from Konrad and Roger.

   - Other minor fixes and improvements."
