Merge tag 'iio-for-3.14b' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

2nd round of new IIO drivers, features and cleanups for the 3.14 cycle.

New drivers

* HID inclinometer driver.

* DHT11 humidity driver.  Note that previous humidity drivers have been in
  hwmon, but no one was ever entirely happy with that, and they should find
  a more comfortable home in IIO (their original placement in hwmon was my
  fault - oops).  As this is our first humidity driver, core support is also
  added.

New features

* Two of mxs-lradc channels are internally wired to a temperature sensor,
  make this explicit in the driver by providing the relevant temperature
  channel.

* Add support for blocking IO on buffers.

* Add a data_available call back to the interface between buffer implementations
  and the core.  This is much cleaner than the old, 'stufftoread' flag.
  Implemented in the kfifo buffer.

Cleanups

* Last user of the old event configuration interface is converted and the
  old interface dropped.  Nice to be rid of this thanks to Lars-Peter's hard
  work!

* Replace all remaining instances of the IIO_ST macro with explicit filling
  of the scan_type structure within struct iio_chan_spec.  This macro was a
  bad idea, that rapidly ceased to cover all elements of the structure.
  Miss reading of the macro arguements has led to a number of bugs so lets
  just get rid of it. The final removal patch is awaiting for some fixes
  to make their way into mainline.
  In a couple of drivers, no elements of scan_type were even being used so
  in those case, it has been dropped entirely.

* Drop a couple of of_match_ptr helper uses in drivers where devicetree is
  not optional and hence the structures being protected by this always exist.

* Fix up some cases where data was read from a device in a particular
  byte order, but he code placed it into a s16 or similar.  These were
  highlighted by Sparse.

* Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers
  core code.

* ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code
  and possibly avoiding issues with i2c bus drivers that assume they can dma
  directly into the buffer.  Note that this cannot currently happen as the the
  i2c_smbus_read_i2c_block_data function has a memcpy from the buffer actually
  passed to the bus driver.  I missed this element of the commit message
  and don't think it is major enough to rebase the iio tree.

* ad5791 and ad5504 stop storing buffers on the stack for an SPI driver.
  Unlike the i2c drivers, this is a real issue for SPI drivers which can dma
  directly into the buffer supplied.

aio: clean up and fix aio_setup_ring page mapping

Since commit 36bc08cc01709 ("fs/aio: Add support to aio ring pages
migration") the aio ring setup code has used a special per-ring backing
inode for the page allocations, rather than just using random anonymous
pages.

However, rather than remembering the pages as it allocated them, it
would allocate the pages, insert them into the file mapping (dirty, so
that they couldn't be free'd), and then forget about them.  And then to
look them up again, it would mmap the mapping, and then use
"get_user_pages()" to get back an array of the pages we just created.

Now, not only is that incredibly inefficient, it also leaked all the
pages if the mmap failed (which could happen due to excessive number of
mappings, for example).

So clean it all up, making it much more straightforward.  Also remove
some left-overs of the previous (broken) mm_populate() usage that was
removed in commit d6c355c7dabc ("aio: fix race in ring buffer page
lookup introduced by page migration support") but left the pointless and
now misleading MAP_POPULATE flag around.

aio/migratepages: make aio migrate pages sane

The arbitrary restriction on page counts offered by the core
migrate_page_move_mapping() code results in rather suspicious looking
fiddling with page reference counts in the aio_migratepage() operation.
To fix this, make migrate_page_move_mapping() take an extra_count parameter
that allows aio to tell the code about its own reference count on the page
being migrated.

While cleaning up aio_migratepage(), make it validate that the old page
being passed in is actually what aio_migratepage() expects to prevent
misbehaviour in the case of races.

Don't set the INITRD_COMPRESS environment variable automatically

Commit 1bf49dd4be0b ("./Makefile: export initial ramdisk compression

depending on which decompression models the kernel had available.

That is completely broken.

For example, we by default have CONFIG_RD_LZ4 enabled, and are able to
decompress such an initrd, but the user tools to *create* such an initrd

mm: fix build of split ptlock code

Commit 597d795a2a78 ('mm: do not allocate page->ptl dynamically, if
spinlock_t fits to long') restructures some allocators that are compiled
even if USE_SPLIT_PTLOCKS arn't used.  It results in compilation
failure:

  mm/memory.c:4282:6: error: 'struct page' has no member named 'ptl'
  mm/memory.c:4288:12: error: 'struct page' has no member named 'ptl'

Add in the missing ifdef.

staging: r8188eu: Fix unused variable warnings

A previous set of patches were test compiled with one of the configuration
variables not set. As a result, a number of unused variables were left in the
code.

In several instances, declaration of the unused variable was the only statement
inside ifdef .. endif pairs. In those cases, the entire block was removed.

mm: do not allocate page->ptl dynamically, if spinlock_t fits to long

In struct page we have enough space to fit long-size page->ptl there,
but we use dynamically-allocated page->ptl if size(spinlock_t) is larger
than sizeof(int).

It hurts 64-bit architectures with CONFIG_GENERIC_LOCKBREAK, where
sizeof(spinlock_t) == 8, but it easily fits into struct page.

drivers/staging/bcm: Integer overflow

The checking condition in 'validateFlash2xReadWrite()' is not
sufficient. A large number invalid would cause an integer overflow and
pass the condition, which could cause further integer overflows in
'Bcmchar.c:bcm_char_ioctl()'.
