Arnd Bergmann 787b0c1f8e serial: pl011: use generic DMA slave configuration if possible
With the new OF DMA binding, it is possible to completely avoid the
need for platform_data for configuring a DMA channel. In cases where the
platform has already been converted, calling dma_request_slave_channel
should get all the necessary information from the device tree.

This also adds a binding document specific to the pl011 controller,
and extends the generic primecell binding to mention "dmas" and other
common properties.

Like the patch that converts the dw_dma controller, this is completely
untested and is looking for someone to try it out.

Meta core internal interrupts (from HWSTATMETA and friends) are vectored
onto the TR1 core trigger for the current thread. This is demultiplexed

External SoC interrupts (from HWSTATEXT and friends) are vectored onto
the TR2 core trigger for the current thread. This is demultiplexed in
irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt.
The external irqchip has devicetree bindings for configuring the number
of irq banks and the type of masking available.

Yinghai Lu 20e6926dcb x86, ACPI, mm: Revert movablemem_map support
Tim found:

  WARNING: at arch/x86/kernel/smpboot.c:324 topology_sane.isra.2+0x6f/0x80()

Don Morris reproduced on a HP z620 workstation, and bisected it to
commit e8d1955258 ("acpi, memory-hotplug: parse SRAT before memblock
is ready")

It turns out movable_map has some problems, and it breaks several things

1. numa_init is called several times, NOT just for srat. so those
	nodes_clear(numa_nodes_parsed)
	memset(&numa_meminfo, 0, sizeof(numa_meminfo))
   can not be just removed.  Need to consider sequence is: numaq, srat, amd, dummy.
   and make fall back path working.

2. simply split acpi_numa_init to early_parse_srat.
   a. that early_parse_srat is NOT called for ia64, so you break ia64.
   b.  for (i = 0; i < MAX_LOCAL_APIC; i++)
	     set_apicid_to_node(i, NUMA_NO_NODE)
     still left in numa_init. So it will just clear result from early_parse_srat.
     it should be moved before that....
   c.  it breaks ACPI_TABLE_OVERIDE...as the acpi table scan is moved
       early before override from INITRD is settled.

3. that patch TITLE is total misleading, there is NO x86 in the title,
   but it changes critical x86 code. It caused x86 guys did not
   pay attention to find the problem early. Those patches really should
   be routed via tip/x86/mm.

4. after that commit, following range can not use movable ram:
  a. real_mode code.... well..funny, legacy Node0 [0,1M) could be hot-removed?
  b. initrd... it will be freed after booting, so it could be on movable...
  c. crashkernel for kdump...: looks like we can not put kdump kernel above 4G
	anymore.
  d. init_mem_mapping: can not put page table high anymore.
  e. initmem_init: vmemmap can not be high local node anymore. That is
     not good.

If node is hotplugable, the mem related range like page table and
vmemmap could be on the that node without problem and should be on that
node.

We have workaround patch that could fix some problems, but some can not
be fixed.

So just remove that offending commit and related ones including:

 f7210e6c4a ("mm/memblock.c: use CONFIG_HAVE_MEMBLOCK_NODE_MAP to
    protect movablecore_map in memblock_overlaps_region().")

 01a178a94e ("acpi, memory-hotplug: support getting hotplug info from
    SRAT")

 27168d38fa ("acpi, memory-hotplug: extend movablemem_map ranges to
    the end of node")

 e8d1955258 ("acpi, memory-hotplug: parse SRAT before memblock is
    ready")

 fb06bc8e5f ("page_alloc: bootmem limit with movablecore_map")

 42f47e27e7 ("page_alloc: make movablemem_map have higher priority")

 6981ec3114 ("page_alloc: introduce zone_movable_limit[] to keep
    movable limit for nodes")

 34b71f1e04 ("page_alloc: add movable_memmap kernel parameter")

 4d59a75125 ("x86: get pg_data_t's memory from other node")

Later we should have patches that will make sure kernel put page table
and vmemmap on local node ram instead of push them down to node0.  Also
need to find way to put other kernel used ram to local node ram.

Merge tag 'arc-v3.9-rc1-late' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc

Pull new ARC architecture from Vineet Gupta:
 "Initial ARC Linux port with some fixes on top for 3.9-rc1:

  I would like to introduce the Linux port to ARC Processors (from
  Synopsys) for 3.9-rc1.  The patch-set has been discussed on the public
  lists since Nov and has received a fair bit of review, specially from
  Arnd, tglx, Al and other subsystem maintainers for DeviceTree, kgdb...

  The arch bits are in arch/arc, some asm-generic changes (acked by
  Arnd), a minor change to PARISC (acked by Helge).

  The series is a touch bigger for a new port for 2 main reasons:

   1. It enables a basic kernel in first sub-series and adds
      ptrace/kgdb/.. later

   2. Some of the fallout of review (DeviceTree support, multi-platform-
      image support) were added on top of orig series, primarily to
      record the revision history.

  This updated pull request additionally contains

   - fixes due to our GNU tools catching up with the new syscall/ptrace
     ABI

   - some (minor) cross-arch Kconfig updates."

 o Add basic support for the Mediatek/Ralink Wireless SoC family.

 o The Qualcomm Atheros platform is extended by support for the new

   ready for OF support.

 o Lantiq and BCM47XX platform have a few improvements and bug fixes.

 o MIPS has sent a few patches that get the kernel ready for the
   upcoming microMIPS support.

 o The rest of the series is made up of small bug fixes and cleanups
   that relate to various parts of the MIPS code.  The biggy in there is
   a whitespace cleanup.  After I was sent another set of whitespace
   cleanup patches I decided it was the time to clean the whitespace
   "issues" for once and and that touches many files below arch/mips/.

Fix up silly conflicts, mostly due to whitespace cleanups.

Linus Torvalds 1a32c58bb9 arm-soc: mvebu platform changes
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.
 
 Merge conflicts:
 
 * in board-nsa310.c, the gpio.h inclusion was removed prematurely and
   put back as a bug fix earlier. With this series it is really not needed
   any more.
 
 * The patch to add rtc support was already applied by Andrew Morton,
   and conflicts with a second copy that was in this series, which adds
   a lot of other devices to arch/arm/boot/dts/armada-370-xp.dtsi.

Linus Torvalds f8f466c817 arm-soc: i.MX DT changes
This branch contains of devicetree changes for the Freescale i.MX platform.
 
 The base patch of the branch changes the format of the dts files to a
 slightly different format that makes it easier to do derivative board
 definitions, but it also introduces a lot of churn in the process since
 every line of the file is touched.
 
 On top of that are a handful of the regular changes; enabling more boards
 as DT-based instead of legacy board files (mx25pdk), enabling another
 driver for devicetree and thus adding bindings (onewire), etc.
 
 I'm not happy about the churn, and will likely not take it for other platforms
 in the future.

Arnd Bergmann f9c6a655a9 dmaengine: dw_dmac: move to generic DMA binding
The original device tree binding for this driver, from Viresh Kumar
unfortunately conflicted with the generic DMA binding, and did not allow
to completely seperate slave device configuration from the controller.

This is an attempt to replace it with an implementation of the generic
binding, but it is currently completely untested, because I do not have
any hardware with this particular controller.

The patch applies on top of the slave-dma tree, which contains both the base
support for the generic DMA binding, as well as the earlier attempt from
Viresh. Both of these are currently not merged upstream however.

This version incorporates feedback from Viresh Kumar, Andy Shevchenko
and Russell King.

This patch removes the useless and outdated bits.  The tools on nbd.sf.net
are fully documented in manpages, which is where documentation for the
non-kernel bits should live.

Additionally, add a reference to the MAINTAINERS file for the nbd-general
mailinglist that is used for discussion of the userland tools and the
kernel module already.

Linus Torvalds 309667e53f Merge branch 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kconfig changes from Michal Marek:
 "I forgot to send a pull request in time for the v3.8-rc1 merge window,
  so the list is a bit longer this time:

   - menuconfig enables extended colors in ncurses if the wide-character
     version is used.

   - CONFIG_ prefix can be specified in the environment to make life
     easier for people using kconfig multiple times in a single tree (no
     functional change in the kernel kconfig usage).

   - kconfig aborts on OOM.

   - inputboxes in menuconfig allow to move the cursor.

   - menuconfig has Save/Load buttons now.

   - xconfig build fix with new g++ and Qt3.

   - nconfig color scheme fix and help text update.

   - make oldconfig prints newlines when output is redirected.

   - some other minor fixes."

Daniel Vetter f00b4dad9d dma-buf: implement vmap refcounting in the interface logic
All drivers which implement this need to have some sort of refcount to
allow concurrent vmap usage. Hence implement this in the dma-buf core.

To protect against concurrent calls we need a lock, which potentially
causes new funny locking inversions. But this shouldn't be a problem
for exporters with statically allocated backing storage, and more
dynamic drivers have decent issues already anyway.

Inspired by some refactoring patches from Aaron Plattner, who
implemented the same idea, but only for drm/prime drivers.

v2: Check in dma_buf_release that no dangling vmaps are left.
Suggested by Aaron Plattner. We might want to do similar checks for
attachments, but that's for another patch. Also fix up ERR_PTR return
for vmap.

v3: Check whether the passed-in vmap address matches with the cached
one for vunmap. Eventually we might want to remove that parameter -
compared to the kmap functions there's no need for the vaddr for
unmapping.  Suggested by Chris Wilson.

v4: Fix a brown-paper-bag bug spotted by Aaron Plattner.

Linus Torvalds d895cb1af1 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs pile (part one) from Al Viro:
 "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
  locking violations, etc.

  The most visible changes here are death of FS_REVAL_DOT (replaced with
  "has ->d_weak_revalidate()") and a new helper getting from struct file
  to inode.  Some bits of preparation to xattr method interface changes.

  Misc patches by various people sent this cycle *and* ocfs2 fixes from
  several cycles ago that should've been upstream right then.

  PS: the next vfs pile will be xattr stuff."

Linus Torvalds 3eb05225ee pwm: Changes for v3.9-rc1
A new driver has been added to support the PWM mode of the timer counter
 blocks found on Atmel AT91 SoCs. The VT8500 driver now supports changing
 the PWM signal polarity and the TI drivers (EHRPWM and ECAP) gained
 suspend and resume functionality.
 
 User drivers can now query the core for whether access to a PWM device
 will sleep (if the PWM chip is on a slow bus such as I2C or SPI).
 
 The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK state
 in addition to the FB layer's blanking states.
 
 To round things off, a few fixes and cleanups are also included.
