The symbol U32_MAX is defined in several spots. Change these
definitions to be conditional. This is in preparation for the next
patch, which centralizes the definition in <linux/kernel.h>.

Compiling a C file which includes genalloc.h but without
spinlock_types.h being included before, we will see the compile error
below.
include/linux/genalloc.h:54:2: error: unknown type name `spinlock_t'
Include spinlock_types.h from genalloc.h to fix the problem.

Add a working sysctl to enable/disable automatic numa memory balancing
at runtime.
This allows us to track down performance problems with this feature and
is generally a good idea.
This was possible earlier through debugfs, but only with special
debugging options set. Also fix the boot message.

When calling free_all_bootmem() the free areas under memblock's control
are released to the buddy allocator. Additionally the reserved list is
freed if it was reallocated by memblock. The same should apply for the
memory list.

We relocate root cache's memcg_params whenever we need to grow the
memcg_caches array to accommodate all kmem-active memory cgroups.
Currently on relocation we free the old version immediately, which can
lead to use-after-free, because the memcg_caches array is accessed
lock-free (see cache_from_memcg_idx()). This patch fixes this by making
memcg_params RCU-protected for root caches.

Currently, we have rather a messy function set relating to per-memcg
kmem cache initialization/destruction.
Per-memcg caches are created in memcg_create_kmem_cache(). This
function calls kmem_cache_create_memcg() to allocate and initialize a
kmem cache and then "registers" the new cache in the
memcg_params::memcg_caches array of the parent cache.
During its work-flow, kmem_cache_create_memcg() executes the following
memcg-related functions:
- memcg_alloc_cache_params(), to initialize memcg_params of the newly
created cache;
- memcg_cache_list_add(), to add the new cache to the memcg_slab_caches
list.
On the other hand, kmem_cache_destroy() called on a cache destruction
only calls memcg_release_cache(), which does all the work: it cleans the
reference to the cache in its parent's memcg_params::memcg_caches,
removes the cache from the memcg_slab_caches list, and frees
memcg_params.
Such an inconsistency between destruction and initialization paths make
the code difficult to read, so let's clean this up a bit.
This patch moves all the code relating to registration of per-memcg
caches (adding to memcg list, setting the pointer to a cache from its
parent) to the newly created memcg_register_cache() and
memcg_unregister_cache() functions making the initialization and
destruction paths look symmetrical.

We do not free the cache's memcg_params if __kmem_cache_create fails.
Fix this.
Plus, rename memcg_register_cache() to memcg_alloc_cache_params(),
because it actually does not register the cache anywhere, but simply
initialize kmem_cache::memcg_params.

Most of the VM_BUG_ON assertions are performed on a page. Usually, when
one of these assertions fails we'll get a BUG_ON with a call stack and
the registers.
I've recently noticed based on the requests to add a small piece of code
that dumps the page to various VM_BUG_ON sites that the page dump is
quite useful to people debugging issues in mm.
This patch adds a VM_BUG_ON_PAGE(cond, page) which beyond doing what
VM_BUG_ON() does, also dumps the page before executing the actual
BUG_ON.

bad_page() is cool in that it prints out a bunch of data about the page.
But, I can never remember which page flags are good and which are bad,
or whether ->index or ->mapping is required to be NULL.
This patch allows bad/dump_page() callers to specify a string about why
they are dumping the page and adds explanation strings to a number of
places. It also adds a 'bad_flags' argument to bad_page(), which it
then dumps out separately from the flags which are actually set.
This way, the messages will show specifically why the page was bad,
*specifically* which flags it is complaining about, if it was a page
flag combination which was the problem.

Pull clk framework changes from Mike Turquette:
"The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions
of existing drivers to the common-clock Device Tree binding, and a few
non-critical fixes to the framework.
Due to an entirely unnecessary cyclical dependency with the arm-soc
tree this pull request is broken into two pieces. The second piece
will be sent out after arm-soc sends you the pull request that merged
in core support for the HiSilicon 3620 platform. That same pull
request from arm-soc depends on this pull request to merge in those
HiSilicon bits without causing build failures"

Some of Qualcomm's clocks can change their parent and rate at the
same time with a single register write. Add support for this
hardware to the common clock framework by adding a new
set_rate_and_parent() op. When the clock framework determines
that both the parent and the rate are going to change during
clk_set_rate() it will call the .set_rate_and_parent() op if
available and fall back to calling .set_parent() followed by
.set_rate() otherwise.

clk_unregister() is currently not implemented and it is required when
a clock provider module needs to be unloaded.
Normally the clock supplier module is prevented to be unloaded by
taking reference on the module in clk_get().
For cases when the clock supplier module deinitializes despite the
consumers of its clocks holding a reference on the module, e.g. when
the driver is unbound through "unbind" sysfs attribute, there are
empty clock ops added. These ops are assigned temporarily to struct
clk and used until all consumers release the clock, to avoid invoking
callbacks from the module which just got removed.

This patch adds common __clk_get(), __clk_put() clkdev helpers that
replace their platform specific counterparts when the common clock
API is used.
The owner module pointer field is added to struct clk so a reference
to the clock supplier module can be taken by the clock consumers.
The owner module is assigned while the clock is being registered,
in functions _clk_register() and __clk_register().

This patch adds support for accuracy retrieval on fixed clocks.
It also adds a new dt property called 'clock-accuracy' to define the clock
accuracy.
This can be usefull for oscillator (RC, crystal, ...) definitions which are
always given an accuracy characteristic.

The clock accuracy is expressed in ppb (parts per billion) and represents
the possible clock drift.
Say you have a clock (e.g. an oscillator) which provides a fixed clock of
20MHz with an accuracy of +- 20Hz. This accuracy expressed in ppb is
20Hz/20MHz = 1000 ppb (or 1 ppm).
Clock users may need the clock accuracy information in order to choose
the best clock (the one with the best accuracy) across several available
clocks.
This patch adds clk accuracy retrieval support for common clk framework by
means of a new function called clk_get_accuracy.
This function returns the given clock accuracy expressed in ppb.
In order to get the clock accuracy, this implementation adds one callback
called recalc_accuracy to the clk_ops structure.
This callback is given the parent clock accuracy (if the clock is not a
root clock) and should recalculate the given clock accuracy.
This callback is optional and may be implemented if the clock is not
a perfect clock (accuracy != 0 ppb).

Pull ARM driver updates from Olof Johansson:
"Updates of SoC-near drivers and other driver updates that makes more
sense to take through our tree.
The largest part of this is a conversion of device registration for
some renesas shmobile/sh devices over to use resources. This has
required coordination with the corresponding arch/sh changes, and
we've agreed to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure
firmware, which is what is used on many of the commercial Nvidia Tegra
products that are in the market, including the Nvidia Shield. The
code is local to arch/arm at this time since it's uncertain whether it
will be shared with arm64 longer-term, if needed we will refactor
later.
A couple of new RTC drivers used on ARM boards, merged through our
tree on request by the RTC maintainer.
... plus a bunch of smaller updates across the board, gpio conversions
for davinci, etc"

Use platform data supplied reset handlers and adjust error

This is an intermediate step before adding support for reset

As the davinci-gpio driver is migrated to use irqdomain
there is no need to pass the irq base for the gpio driver.
This patch removes this variable from davinci_gpio_platform_data
and also the refrences from the machine file.

Pull ARM SoC DT updates from Olof Johansson:
"DT and DT-conversion-related changes for various ARM platforms. Most
of these are to enable various devices on various boards, etc, and not
necessarily worth enumerating.
New boards and systems continue to come in as new devicetree files
that don't require corresponding C changes any more, which is
indicating that the system is starting to work fairly well.
A few things worth pointing out:
* ST Ericsson ux500 platforms have made the major push to move over
to fully support the platform with DT
* Renesas platforms continue their conversion over from legacy
platform devices to DT-based for hardware description"

The R-Car Gen2 SoCs (R8A7790 and R8A7791) have several clocks that are
too custom to be supported in a generic driver. Those clocks can be
divided in two categories:
- Fixed rate clocks with multiplier and divisor set according to boot
mode configuration
- Custom divider clocks with SoC-specific divider values
This driver supports both.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/dt
From Linus Walleij:
Ux500 device tree patches for v3.14, take one:
- Fix up tc3589x bindings so this chip works again.
- Remove SSP platform devices, as we now boot from device tree
exclusively.
- Delete surplus AB8500/DB8500 platform data, not obtained from
the device tree.
- Add DMA config for the MSP devices.
- A series of 21 patches moving pin control config for the
on-chip Nomadik pin controller from the board file
to the device tree, step by step.
- Two patches to the STE DMA40 driver regarding the high-prio
DMA channel so this can be moved to the device tree. Both have
Vinod's ACK.
- Decommission of the non-device tree boot path for the timer
initialization code.
- Deletion of the non-devicetree probe path from the MTU timer
driver, as all platforms using it are now using device tree.
This has Daniel Lezcano's ACK.

Both platforms using the MTU (Nomadik and Ux500) have now been
converted to use device tree exclusively, thus let us delete
this platform data header and make this driver a fully
self-contained DT-only driver.

This decomissions the platform data header (which is no longer
in use after the systems using this driver were switched to
a pure device-tree config path) and merges the result into
the driver file or local driver header.

Pull ARM SoC platform changes from Olof Johansson:
"New core SoC-specific changes.
New platforms:
* Introduction of a vendor, Hisilicon, and one of their SoCs with
some random numerical product name.
* Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m,
i.e. !MMU).
* Marvell Berlin series of SoCs, which include the one in Chromecast.
* MOXA platform support, ARM9-based platform used mostly in
industrial products
* Support for Freescale's i.MX50 SoC.
Other work:
* Renesas work for new platforms and drivers, and conversion over to
more multiplatform-friendly device registration schemes.
* SMP support for Allwinner sunxi platforms.
* ... plus a bunch of other stuff across various platforms"

From Stephen Warren:
ARM: tegra: powergate driver changes
This branch includes all the changes to Tegra's powergate driver for 3.14.
These are separate out, since the Tegra DRM changes for 3.14 rely on the
new APIs introduced here.
A few cleanups and fixes are included, plus additions of Tegra124 SoC
support, and a new API for manipulating Tegra's IO rail deep power down
states.
This branch is based on tag tegra-for-3.14-dmas-resets-rework, in order
to avoid conflicts with the addition of common reset controller support
to the powergate driver.
* tag 'tegra-for-3.14-powergate' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
ARM: tegra: Add IO rail support
ARM: tegra: Special-case the 3D clamps on Tegra124
ARM: tegra: Add Tegra124 powergate support
ARM: tegra: Export tegra_powergate_remove_clamping()
ARM: tegra: Export tegra_powergate_power_off()
ARM: tegra: Rename cpu0 powergate to crail
ARM: tegra: Fix some whitespace oddities

Pull ARM SoC cleanups from Olof Johansson:
"This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep
it strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared
with Mike Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.
* Removal of some header files on exynos to prepare for
multiplatform"
