staging/zcache: Fix/improve zcache writeback code, tie to a config option
It was observed by Andrea Arcangeli in 2011 that zcache can get "full"
and there must be some way for compressed swap pages to be (uncompressed
and then) sent through to the backing swap disk. A prototype of this
functionality, called "unuse", was added in 2012 as part of a major update
to zcache (aka "zcache2"), but was left unfinished due to the unfortunate
temporary fork of zcache.
This earlier version of the code had an unresolved memory leak
and was anyway dependent on not-yet-upstream frontswap and mm changes.
The code was meanwhile adapted by Seth Jennings for similar
functionality in zswap (which he calls "flush"). Seth also made some
clever simplifications which are herein ported back to zcache. As a
result of those simplifications, the frontswap changes are no longer
necessary, but a slightly different (and simpler) set of mm changes are
still required [1]. The memory leak is also fixed.
Due to feedback from akpm in a zswap thread, this functionality in zcache
has now been renamed from "unuse" to "writeback".
Although this zcache writeback code now works, there are open questions
as how best to handle the policy that drives it. As a result, this
patch also ties writeback to a new config option. And, since the
code still depends on not-yet-upstreamed mm patches, to avoid build
problems, the config option added by this patch temporarily depends
on "BROKEN"; this config dependency can be removed in trees that
contain the necessary mm patches.

Jonathan writes:
"4th set of IIO new drivers cleanups and fixes for the 3.9 cycle
+ a new spi helper function.
1) Introduce spi_sync_transfer and use it within IIO. Originally
it was envisioned that this nice little boilerplate replacement
would go through the spi tree, but Grant Likely stated he'd
prefer we take it through IIO as the example usecases were all
in IIO (and are also in this pull request). Note that given
their may have been some unresolved elements related to the
coccinelle element of the patch, that has been stripped out
and will doubtlessly follow at a later date (along with
lots of other patches for drivers elsewhere in the tree).
2) New Invensense MPU6050 driver. This is stripped down to pretty
much the basics from the original submission with the intent
to build up all the fancy bits in an incremental (and hence
reviewable fashion). It's been through a good few revisions
so nice to finally merge this.
3) Change to iio_channel_get api to simplify device tree based
mappings. The actual mappings are currently under review.
4) Build fixes for !CONFIG_IIO_TRIGGER in the st_sensors driver.
This one snuck past during review and testing but got picked
up by Randy Dunlap in a randconfig build.
5) Some max1363 cleanups and enhancements.
6) Some comment fixes to make them coherent and comprehensible.
7) Trivial build warning fix in mxs-lradc"

spi: Add helper functions for setting up transfers
Quite often the pattern used for setting up and transferring a synchronous SPI
transaction looks very much like the following:
struct spi_message msg;
struct spi_transfer xfers[] = {
...
};
spi_message_init(&msg);
spi_message_add_tail(&xfers[0], &msg);
...
spi_message_add_tail(&xfers[ARRAY_SIZE(xfers) - 1], &msg);
ret = spi_sync(&msg);
This patch adds two new helper functions for handling this case. The first
helper function spi_message_init_with_transfers() takes a spi_message and an
array of spi_transfers. It will initialize the message and then call
spi_message_add_tail() for each transfer in the array. E.g. the following
spi_message_init(&msg);
spi_message_add_tail(&xfers[0], &msg);
...
spi_message_add_tail(&xfers[ARRAY_SIZE(xfers) - 1], &msg);
can be rewritten as
spi_message_init_with_transfers(&msg, xfers, ARRAY_SIZE(xfers));
The second function spi_sync_transfer() takes a SPI device and an array of
spi_transfers. It will allocate a new spi_message (on the stack) and add all
transfers in the array to the message. Finally it will call spi_sync() on the
message.
E.g. the follwing
struct spi_message msg;
struct spi_transfer xfers[] = {
...
};
spi_message_init(&msg);
spi_message_add_tail(&xfers[0], &msg);
...
spi_message_add_tail(&xfers[ARRAY_SIZE(xfers) - 1], &msg);
ret = spi_sync(spi, &msg);
can be rewritten as
struct spi_transfer xfers[] = {
...
};
ret = spi_sync_transfer(spi, xfers, ARRAY_SIZE(xfers));
A coccinelle script to find such instances will follow.

"Third set of IIO new drivers, cleanups and fixes for the 3.9 cycle
New drivers
1) A driver for ST microelectronics sensors. This driver already covers
a large set of new parts (20 gyros, accelerometer and magnetometers)
not currently covered by the existing drivers. The intent moving forward
is to merge this with the other drivers for similar parts already in tree.
The lis3l02dq driver currently in staging/iio will be trivial, the lis3
driver in misc more complex as it has a number of additional interfaces.
Any merging in of the lis3 driver will rely on the not currently
merged iio_input bridge driver and handling of freefall notifications
etc.
2) A driver for the itg3200 gyroscope.
Graduations from staging
1) Cleanup and move out of staging of the adxrs450 gyroscope driver. The
cleanup required was all minor but there were a couple of fixes hidden in
there.
Core and driver additions
1) Initial work from Guenter Roeck on device tree support for IIO's provider/
consumer code. Focuses on the iio_hwmon driver and the max1363 adc driver.
The full device tree syntax is currently under discussion but should
follow shortly.
Cleanups and fixes
1) Remove a noop function __iio_update_buffer
2) Couple of small fixes and cleanups for the max1363

staging: comedi: check s->async for poll(), read() and write()
Some low-level comedi drivers (incorrectly) point `dev->read_subdev` or
`dev->write_subdev` to a subdevice that does not support asynchronous
commands. Comedi's poll(), read() and write() file operation handlers
assume these subdevices do support asynchronous commands. In
particular, they assume `s->async` is valid (where `s` points to the
read or write subdevice), which it won't be if it has been set
incorrectly. This can lead to a NULL pointer dereference.
Check `s->async` is non-NULL in `comedi_poll()`, `comedi_read()` and
`comedi_write()` to avoid the bug.
