5ea3b1b2f8 cma: add placement specifier for "cma=" kernel parameter 
Currently, "cma=" kernel parameter is used to specify the size of CMA,
but we can't specify where it is located.  We want to locate CMA below
4GB for devices only supporting 32-bit addressing on 64-bit systems
without iommu.

This enables to specify the placement of CMA by extending "cma=" kernel
parameter.

Examples:
 1. locate 64MB CMA below 4GB by "cma=64M@0-4G"
 2. locate 64MB CMA exact at 512MB by "cma=64M@512M"

Note that the DMA contiguous memory allocator on x86 assumes that
page_address() works for the pages to allocate.  So this change requires
to limit end address of contiguous memory area upto max_pfn_mapped to
prevent from locating it on highmem area by the argument of
dma_contiguous_reserve().

2bfc2862c4 memblock: introduce memblock_alloc_range() 
This introduces memblock_alloc_range() which allocates memblock from the
specified range of physical address.  I would like to use this function
to specify the location of CMA.

9c5a362142 x86: enable DMA CMA with swiotlb 
The DMA Contiguous Memory Allocator support on x86 is disabled when
swiotlb config option is enabled.  So DMA CMA is always disabled on
x86_64 because swiotlb is always enabled.  This attempts to support for
DMA CMA with enabling swiotlb config option.

The contiguous memory allocator on x86 is integrated in the function
dma_generic_alloc_coherent() which is .alloc callback in nommu_dma_ops
for dma_alloc_coherent().

x86_swiotlb_alloc_coherent() which is .alloc callback in swiotlb_dma_ops
tries to allocate with dma_generic_alloc_coherent() firstly and then
swiotlb_alloc_coherent() is called as a fallback.

The main part of supporting DMA CMA with swiotlb is that changing
x86_swiotlb_free_coherent() which is .free callback in swiotlb_dma_ops
for dma_free_coherent() so that it can distinguish memory allocated by
dma_generic_alloc_coherent() from one allocated by
swiotlb_alloc_coherent() and release it with dma_generic_free_coherent()
which can handle contiguous memory.  This change requires making
is_swiotlb_buffer() global function.

This also needs to change .free callback in the dma_map_ops for amd_gart
and sta2x11, because these dma_ops are also using
dma_generic_alloc_coherent().

52383431b3 mm: get rid of __GFP_KMEMCG 
Currently to allocate a page that should be charged to kmemcg (e.g.
threadinfo), we pass __GFP_KMEMCG flag to the page allocator.  The page
allocated is then to be freed by free_memcg_kmem_pages.  Apart from
looking asymmetrical, this also requires intrusion to the general
allocation path.  So let's introduce separate functions that will
alloc/free pages charged to kmemcg.

The new functions are called alloc_kmem_pages and free_kmem_pages.  They
should be used when the caller actually would like to use kmalloc, but
has to fall back to the page allocator for the allocation is large.
They only differ from alloc_pages and free_pages in that besides
allocating or freeing pages they also charge them to the kmem resource
counter of the current memory cgroup.

5dfb417509 sl[au]b: charge slabs to kmemcg explicitly 
We have only a few places where we actually want to charge kmem so
instead of intruding into the general page allocation path with
__GFP_KMEMCG it's better to explictly charge kmem there.  All kmem
charges will be easier to follow that way.

This is a step towards removing __GFP_KMEMCG.  It removes __GFP_KMEMCG
from memcg caches' allocflags.  Instead it makes slab allocation path
call memcg_charge_kmem directly getting memcg to charge from the cache's
memcg params.

This also eliminates any possibility of misaccounting an allocation
going from one memcg's cache to another memcg, because now we always
charge slabs against the memcg the cache belongs to.  That's why this
patch removes the big comment to memcg_kmem_get_cache.

c46a7c817e x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels 
_PAGE_NUMA is currently an alias of _PROT_PROTNONE to trap NUMA hinting
faults on x86.  Care is taken such that _PAGE_NUMA is used only in
situations where the VMA flags distinguish between NUMA hinting faults
and prot_none faults.  This decision was x86-specific and conceptually
it is difficult requiring special casing to distinguish between PROTNONE
and NUMA ptes based on context.

Fundamentally, we only need the _PAGE_NUMA bit to tell the difference
between an entry that is really unmapped and a page that is protected
for NUMA hinting faults as if the PTE is not present then a fault will
be trapped.

Swap PTEs on x86-64 use the bits after _PAGE_GLOBAL for the offset.
This patch shrinks the maximum possible swap size and uses the bit to
uniquely distinguish between NUMA hinting ptes and swap ptes.

This patch makes generic_file_fsync() issue proper cache flush to fix the

c177c81e09 hugetlb: restrict hugepage_migration_support() to x86_64 
Currently hugepage migration is available for all archs which support
pmd-level hugepage, but testing is done only for x86_64 and there're
bugs for other archs.  So to avoid breaking such archs, this patch
limits the availability strictly to x86_64 until developers of other
archs get interested in enabling this feature.

Simply disabling hugepage migration on non-x86_64 archs is not enough to
fix the reported problem where sys_move_pages() hits the BUG_ON() in
follow_page(FOLL_GET), so let's fix this by checking if hugepage
migration is supported in vma_migratable().

4dc4226f99 ACPI and power management updates for 3.16-rc1 
- ACPICA update to upstream version 20140424.  That includes a
    number of fixes and improvements related to things like GPE
    handling, table loading, headers, memory mapping and unmapping,
    DSDT/SSDT overriding, and the Unload() operator.  The acpidump
    utility from upstream ACPICA is included too.  From Bob Moore,
    Lv Zheng, David Box, David Binderman, and Colin Ian King.

    affect several places including cpuidle, PM core, ACPI core, and
    the ACPI battery driver.  From Rafael J Wysocki and Zhang Rui.
 
  - Miscellaneous fixes and updates of the ACPI core from Aaron Lu,
    Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki.

Pull ACPI and power management updates from Rafael Wysocki:
 "ACPICA is the leader this time (63 commits), followed by cpufreq (28
  commits), devfreq (15 commits), system suspend/hibernation (12
  commits), ACPI video and ACPI device enumeration (10 commits each).

  We have no major new features this time, but there are a few
  significant changes of how things work.  The most visible one will
  probably be that we are now going to create platform devices rather
  than PNP devices by default for ACPI device objects with _HID.  That
  was long overdue and will be really necessary to be able to use the
  same drivers for the same hardware blocks on ACPI and DT-based systems
  going forward.  We're not expecting fallout from this one (as usual),
  but it's something to watch nevertheless.

  The second change having a chance to be visible is that ACPI video
  will now default to using native backlight rather than the ACPI
  backlight interface which should generally help systems with broken
  Win8 BIOSes.  We're hoping that all problems with the native backlight
  handling that we had previously have been addressed and we are in a
  good enough shape to flip the default, but this change should be easy
  enough to revert if need be.

  In addition to that, the system suspend core has a new mechanism to
  allow runtime-suspended devices to stay suspended throughout system
  suspend/resume transitions if some extra conditions are met
  (generally, they are related to coordination within device hierarchy).
  However, enabling this feature requires cooperation from the bus type
  layer and for now it has only been implemented for the ACPI PM domain
  (used by ACPI-enumerated platform devices mostly today).

  Also, the acpidump utility that was previously shipped as a separate
  tool will now be provided by the upstream ACPICA along with the rest
  of ACPICA code, which will allow it to be more up to date and better
  supported, and we have one new cpuidle driver (ARM clps711x).

  The rest is improvements related to certain specific use cases,
  cleanups and fixes all over the place.

  Specifics:

   - ACPICA update to upstream version 20140424.  That includes a number
     of fixes and improvements related to things like GPE handling,
     table loading, headers, memory mapping and unmapping, DSDT/SSDT
     overriding, and the Unload() operator.  The acpidump utility from

     machines and using native backlight by default.

   - ACPI device enumeration changes to create platform devices rather
     than PNP devices for ACPI device objects with _HID by default.  PNP
     devices will still be created for the ACPI device object with
     device IDs corresponding to real PNP devices, so that change should
     not break things left and right, and we're expecting to see more
     and more ACPI-enumerated platform devices in the future.  From
     Zhang Rui and Rafael J Wysocki.

   - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it
     to handle system suspend/resume on Asus T100 correctly.  From

ba1bdefec3 This must be about the smallest merge window patch set ever for GFS2. 
It is probably also the first one without a single patch from me. That
 is down to a combination of factors, and I have some things in the works
 that are not quite ready yet, that I hope to put in next time around.
 
 Returning to what is here this time... we have 3 patches which fix
 various warnings. Two are bug fixes (for quotas and also a
 rare recovery race condition). The final patch, from Ben Marzinski,
 is an important change in the freeze code which has been in
 progress for some time. This removes the need to take and drop the
 transaction lock for every single transaction, when the only time it
 was used, was at file system freeze time. Ben's patch integrates the
 freeze operation into the journal flush code as an alternative with
 lower overheads and also lands up resolving some difficult to fix races
 at the same time.

Pull gfs2 updates from Steven Whitehouse:
 "This must be about the smallest merge window patch set ever for GFS2.
  It is probably also the first one without a single patch from me.
  That is down to a combination of factors, and I have some things in
  the works that are not quite ready yet, that I hope to put in next
  time around.

  Returning to what is here this time...  we have 3 patches which fix
  various warnings.  Two are bug fixes (for quotas and also a rare
  recovery race condition).  The final patch, from Ben Marzinski, is an
  important change in the freeze code which has been in progress for
  some time.  This removes the need to take and drop the transaction
  lock for every single transaction, when the only time it was used, was
  at file system freeze time.  Ben's patch integrates the freeze
  operation into the journal flush code as an alternative with lower
  overheads and also lands up resolving some difficult to fix races at
  the same time"

64c5c75908 of/irq: provide more wrappers for !CONFIG_OF 
The pci-rcar driver is enabled for compile tests, and this has
now shown that the driver cannot build without CONFIG_OF,
following the inclusion of f8f2fe7355 "PCI: rcar: Use new OF
interrupt mapping when possible":

drivers/built-in.o: In function `rcar_pci_map_irq':
:(.text+0x1cc7c): undefined reference to `of_irq_parse_and_map_pci'
pci/host/pcie-rcar.c: In function 'pci_dma_range_parser_init':
pci/host/pcie-rcar.c:875:2: error: implicit declaration of function 'of_n_addr_cells' [-Werror=implicit-function-declaration]

As pointed out by Ben Dooks and Geert Uytterhoeven, this is actually
supposed to build fine, which we can achieve if we make the
declaration of of_irq_parse_and_map_pci conditional on CONFIG_OF
and provide an empty inline function otherwise, as we do for
a lot of other of interfaces.

This lets us build the rcar_pci driver again without CONFIG_OF
for build testing. All platforms using this driver select OF,
so this doesn't change anything for the users.

312c76f1a3 regulator: Updates for v3.16 
The bulk of the changes for this release are a few new drivers however
 there are a couple of noticable core changes and the usual stream of
 cleanups and fixes:
 
  - Move disable of unused regulators later in init so it comes after
    deferred probe has iterated making startup smoother.
  - Fixes reference counting of the DT nodes for constraints from Charles
    Keepax.  This has little practical impact since all real users of
    the regulator bindings use FDT which doesn't need the reference
    counting.
  - Lots of cleanups, especially to the Samsung drivers.
  - Support for Linear Technologies LTC3589, Texas Instruments TPS658640
    and X-Powers AXP20x.

e13cccfd86 spi: Updates for v3.16 
For this release SPI has been exceptionally quiet, all the work has been
 on improving drivers (including taking advantage of some of the recent
 framework updates):
 
  - DMA support for the rspi driver providing a nice performance boost.
  - Performance improvement for the SIRF controller in PIO mode.
  - New support for the Cadence SPI IP and for pxa2xx on BayTrail.

Pull first set of s390 updates from Martin Schwidefsky:
 "The biggest change in this patchset is conversion from the bootmem
  bitmaps to the memblock code.  This conversion requires two common
  code patches to introduce the 'physmem' memblock list.

  We experimented with ticket spinlocks but in the end decided against
  them as they perform poorly on virtualized systems.  But the spinlock
  cleanup and some small improvements are included.

  The uaccess code got another optimization, the get_user/put_user calls
  are now inline again for kernel compiles targeted at z10 or newer
  machines.  This makes the text segment shorter and the code gets a
  little bit faster.

  And as always some bug fixes"

e5c4ecdc55 USB driver patches for 3.16-rc1 
Here is the big USB driver pull request for 3.16-rc1.
 
 Nothing huge here, but lots of little things in the USB core, and in
 lots of drivers.  Hopefully the USB power management will be work better
 now that it has been reworked to do per-port power control dynamically.
 There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG
 is finally gone now that everything has been converted over to the
 dynamic debug inteface, the last hold-out drivers were cleaned up and
 the config option removed.  There were also other minor things all
 through the drivers/usb/ tree, the shortlog shows this pretty well.
 
 All have been in linux-next, including the very last patch, which came
 from linux-next to fix a build issue on some platforms.

 Lots of stuff here, tons of cleanup patches, a few new drivers, and some

 deleted.
 
 One notible bit of work did stand out, Jes Sorensen has gone on a tear,
 fixing up a wireless driver to be "more sane" than it originally was
 from the vendor, with over 500 patches merged here.  Good stuff, and a
 number of users laptops are better off for it.

5da77761e6 Driver core / kernfs pull request for 3.16-rc1 
Here is the "big" pull request for 3.16-rc1.
 Not a lot of changes here, some kernfs work, a revert of a very old
 driver core change that ended up cauing some memory leaks on driver
 probe error paths, and other minor things.
 
 As was pointed out earlier today, one commit here,
 26fc9cd200 (kernfs: move the last
 knowledge of sysfs out from kernfs) is also needed in your 3.15-final
 branch as well.  If you could cherry-pick it there, it would be most
 appreciated by Andy Lutomirski to prevent a regression there.

  Not a lot of changes here, some kernfs work, a revert of a very old
  driver core change that ended up cauing some memory leaks on driver
  probe error paths, and other minor things.

  As was pointed out earlier today, one commit here, 26fc9cd200
  ("kernfs: move the last knowledge of sysfs out from kernfs") is also
  needed in your 3.15-final branch as well.  If you could cherry-pick it
  there, it would be most appreciated by Andy Lutomirski to prevent a
  regression there.

  All of these have been in linux-next for a while"
