staging, android: remove lowmemory killer from the tree

Lowmemory killer is sitting in the staging tree since 2008 without any
serious interest for fixing issues brought up by the MM folks. The main
objection is that the implementation is basically broken by design:
- it hooks into slab shrinker API which is not suitable for this
  purpose. lowmem_count implementation just shows this nicely.
  There is no scaling based on the memory pressure and no
  feedback to the generic shrinker infrastructure.
  Moreover lowmem_scan is called way too often for the heavy
  work it performs.
- it is not reclaim context aware - no NUMA and/or memcg
  awareness.

As the code stands right now it just adds a maintenance overhead when
core MM changes have to update lowmemorykiller.c as well. It also seems
that the alternative LMK implementation will be solely in the userspace
so this code has no perspective it seems. The staging tree is supposed
to be for a code which needs to be put in shape before it can be merged
which is not the case here obviously.

staging: vchiq_arm: Disable ability to dump memory by default

if the devtmpfs node doesn't have adequate permissions set.

Since the ability to dump memory still has debugging value,
create a new build configuration and disable the feature

staging: vchiq_arm: Add compatibility wrappers for ioctls

This patch adds compatibility wrappers for the ioctls
exposed by vchiq/vc04_services.  The compat ioctls are
completely implemented on top of the native ioctls.  No
existing lines are modified.

While the ideal approach would be to cleanup the existing
code, this path is simplier and easier to review. While
it does have a small runtime performance penality vs
seperating the existing code into wrapper+worker functions,
the penality is small since only the metadata is copied
back onto the 32 bit user mode stack.

The on top of approach is the approach used by several
existing performance critical subsystems of Linux such
as the DRM 3D graphics subsystem.

Testing:

1. A 32 bit chroot was created on a RPI 3 and vchiq_test
was built for armhf.  The usual tests were run such as
vchiq_test -f 10 and vchiq_test -p.

2. This patch was copied onto the shipping version of
the Linux kernel used for the RPI and that kernel was
built for arm64. That kernel was used to boot Raspbian.
Many of the builtin features are now functional such
as the "hello_pi" examples, and minecraft_pi.

staging: bcm2835_camera: Use a mapping table for context field of mmal_msg_header

The camera driver passes messages back and forth between the firmware with
requests and replies.  One of the fields of the message header called
context is a pointer so the size changes between 32 bit and 64 bit.

The context field is used to pair reply messages from the firmware with
request messages from the kernel.  The simple solution would be
to use the padding field for the upper 32 bits of pointers, but this
would rely on the firmware always copying the pad field.

So instead handles are generated that are 32 bit numbers and a mapping
stored in a btree as implemented by the btree library in the kernel lib
directory.  The mapping pairs the handle with the pointer to the actual
data. The btree library was chosen since it's very easy to use and
red black trees would be overkill.

The camera driver also now forces in the btree library if the camera is
included in the build.  The btree library is a hidden configuration
option.

Luckly, the field is not interperated by the driver, so it can be changed

Merge tag 'iio-for-4.12a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of IIO new device support, features and cleanup for the 4.12 cycle.

Quite a bit of outreachy activity here with a driver from a current intern
and a number of cleanup patches as part of the next round.

Getting a pull request in early this cycle as it's looking like another large
cycle for IIO.

New device support
* adxl345
  - initial device support. Note, once complete support is done the intent
    is to superceded the driver in input/misc.
  - bindings.
  - conversion from i2c direct calls to regmap and driver split.
  - spi support.
* chromeos light and proximity.

staging/atomisp: Add support for the Intel IPU v2

This patch adds support for the Intel IPU v2 as found on Android and IoT
Baytrail-T and Baytrail-CR platforms (those with the IPU PCI mapped). You
will also need the firmware files from your device (Android usually puts
them into /etc) - or you can find them in the downloadable restore/upgrade
kits if you blew them away for some reason.

It may be possible to extend the driver to handle the BYT/T windows
platforms such as the ASUS T100TA. These platforms don't expose the IPU via
the PCI interface but via ACPI buried in the GPU description and with the
camera information somewhere unknown so would need a platform driver
interface adding to the codebase *IFF* the firmware works on such devices.

To get good results you also need a suitable support library such as
libxcam. The camera is intended to be driven from Android so it has a lot of
features that many desktop apps don't fully spport.

In theory all the pieces are there to build it with -DISP2401 and some
differing files to get CherryTrail/T support, but unifying the drivers
properlly is a work in progress.

The IPU driver represents the work of a lot of people within Intel over many
years. It's historical goal was portability rather than Linux upstream. Any
queries about the upstream aimed driver should be sent to me not to the
original authors.
