git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup
Timer clean-up to get us closer to moving timer code to drivers,
and to get rid of CONFIG_OMAP_32K_TIMER and rely on the board
or devicetree provided timer configuration.
Note that these changes are on top of the recent timer fixes.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/cleanup
From Linus Walleij <linus.walleij@linaro.org>:
This series will do the following:
- Switch the Integrator/AP and /CP to use the SoC bus
when booting from device tree.
- Group all devices on the SoC below this bus so as to
set a good example of how to do this. The bus was
invented by Lee Jones, let's show how it's to be used
on a DT:ed SoC.
- Fetch the special system controller offsets from two
special device tree nodes for each case and replace
the static mappings with these at boot.
- Move some static remaps to the ATAG-only code path
and delete some static maps that aren't used.
- Push dependencies on system controller remaps down
to the Integrator/AP board file and the PCIv3 driver
respectively and use only dynamic remappings.
- Fix up conditional BUG() usage in the PCIv3 driver
to be simpler and more to the point.

The Marvell 98DX412x SoC embed a kirkwood variant that does not have
pinctrl support yet. Even though this kirkwood is very similar to the
88f6281, on the MPP front a lot of pins are not available. That's why a
new kirkwood pinctrl variant is needed.

This patch adds a way to specify bindings between devices and power
domains using device tree.
A device can be bound to particular power domain by adding a
power-domain property containing a phandle to the domain. The device
will be bound to the domain before binding a driver to it and unbound
after unbinding a driver from it.

When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-<bus-num>"
Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.
Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.
So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

memcg: oom: fix totalpages calculation for memory.swappiness==0
mm: fix build warning for uninitialized value
mm: add anon_vma_lock to validate_mm()
|
|
oom_badness() takes a totalpages argument which says how many pages are
available and it uses it as a base for the score calculation. The value
is calculated by mem_cgroup_get_limit which considers both limit and
total_swap_pages (resp. memsw portion of it).
This is usually correct but since fe35004fbf9e ("mm: avoid swapping out
with swappiness==0") we do not swap when swappiness is 0 which means
that we cannot really use up all the totalpages pages. This in turn
confuses oom score calculation if the memcg limit is much smaller than
the available swap because the used memory (capped by the limit) is
negligible comparing to totalpages so the resulting score is too small
if adj!=0 (typically task with CAP_SYS_ADMIN or non zero oom_score_adj).
A wrong process might be selected as result.
The problem can be worked around by checking mem_cgroup_swappiness==0
and not considering swap at all in such a case.

This is mostly a revert of 01dc52ebdf47 ("oom: remove deprecated oom_adj")
from Davidlohr Bueso.
It reintroduces /proc/pid/oom_adj for backwards compatibility with earlier
kernels. It simply scales the value linearly when /proc/pid/oom_score_adj
is written.
The major difference is that its scheduled removal is no longer included
in Documentation/feature-removal-schedule.txt. We do warn users with a
single printk, though, to suggest the more powerful and supported
/proc/pid/oom_score_adj interface.

Provide simplified models for the necessary clocks on the zynq-7000
platform. Currently, the PLLs, the CPU clock network, and the basic
peripheral clock networks (for SDIO, SMC, SPI, QSPI, UART) are modelled.
OF bindings are also provided and documented.

Separate patches from Marek Szyprowski <m.szyprowski@samsung.com>:
Commit e9da6e9905e639b0 ("ARM: dma-mapping: remove custom consistent dma
region") replaced custom consistent memory handling, so setting
consistent dma memory size is not longer required. This patch series
cleans sub-architecture platform code to remove all calls to the
obsolated init_consistent_dma_size() function and finally removes the
init_consistent_dma_size() stub itself.
* cleanups/dma:
ARM: at91: remove obsoleted init_consistent_dma_size()
ARM: u300: remove obsoleted init_consistent_dma_size()
ARM: dma-mapping: remove init_consistent_dma_size() stub
ARM: shmobile: remove obsoleted init_consistent_dma_size()
ARM: davinci: remove obsoleted init_consistent_dma_size()
ARM: samsung: remove obsoleted init_consistent_dma_size()

This adds a i.MX25 dtsi file along with the i.MX25 clock tree
documentation. The devicetree should be fairly complete for:
- uart
- fec
- i2c
- spi
- pwm
- nand
- gpio
- wdog
- esdhc
- flexcan
The more exotic devices currently miss clock bindings.

This switches the way that pins are reserved for multiplexing:
We used to do this when the map was parsed, at the creation of
the settings inside the pinctrl handle, in pinmux_map_to_setting().
However this does not work for us, because we want to use the
same set of pins with different devices at different times: the
current code assumes that the pin groups in a pinmux state will
only be used with one single device, albeit different groups can
be active at different times. For example if a single I2C driver
block is used to drive two different busses located on two
pin groups A and B, then the pins for all possible states of a
function are reserved when fetching the pinctrl handle: the
I2C bus can choose either set A or set B by a mux state at
runtime, but all pins in both group A and B (the superset) are
effectively reserved for that I2C function and mapped to the
device. Another device can never get in and use the pins in
group A, even if the device/function is using group B at the
moment.
Instead: let use reserve the pins when the state is activated
and drop them when the state is disabled, i.e. when we move to
another state. This way different devices/functions can use the
same pins at different times.
We know that this is an odd way of doing things, but we really
need to switch e.g. an SD-card slot to become a tracing output
sink at runtime: we plug in a special "tracing card" then mux
the pins that used to be an SD slot around to the tracing
unit and push out tracing data there instead of SD-card
traffic.
As a side effect pinmux_free_setting() is unused but the stubs
are kept for future additions of code.
