3be91c4a3d block: Deprecate the use of the term sector in the context of block integrity
The protection interval is not necessarily tied to the logical block
size of a block device. Stop using the terms "sector" and "sectors".

Going forward we will use the term "seed" to describe the initial
reference tag value for a given I/O. "Interval" will be used to describe
the portion of the data buffer that a given piece of protection
information is associated with.

8492b68bc4 block: Remove integrity tagging functions
None of the filesystems appear interested in using the integrity tagging
feature. Potentially because very few storage devices actually permit
using the application tag space.

Remove the tagging functions.

180b2f95dd block: Replace bi_integrity with bi_special
For commands like REQ_COPY we need a way to pass extra information along
with each bio. Like integrity metadata this information must be
available at the bottom of the stack so bi_private does not suffice.

Rename the existing bi_integrity field to bi_special and make it a union
so we can have different bio extensions for each class of command.

We previously used bi_integrity != NULL as a way to identify whether a
bio had integrity metadata or not. Introduce a REQ_INTEGRITY to be the
indicator now that bi_special can contain different things.

In addition, bio_integrity(bio) will now return a pointer to the
integrity payload (when applicable).

824269c586 staging:iio:ad5933: Fix NULL pointer deref when enabling buffer
In older versions of the IIO framework it was possible to pass a
completely different set of channels to iio_buffer_register() as the one
that is assigned to the IIO device. Commit 959d2952d1 ("staging:iio: make
iio_sw_buffer_preenable much more general.") introduced a restriction that
requires that the set of channels that is passed to iio_buffer_register() is
a subset of the channels assigned to the IIO device as the IIO core will use
the list of channels that is assigned to the device to lookup a channel by
scan index in iio_compute_scan_bytes(). If it can not find the channel the
function will crash. This patch fixes the issue by making sure that the same
set of channels is assigned to the IIO device and passed to
iio_buffer_register().

Fixes the follow NULL pointer derefernce kernel crash:

37e1041f04 clk: sunxi: mod0: Introduce MMC proper phase handling
The MMC clock we thought we had until now are actually not one but three
different clocks.

The main one is unchanged, and will have three outputs:
  - The clock fed into the MMC
  - a sample and output clocks, to deal with when should we output/sample data
    to/from the MMC bus

The phase control we had are actually controlling the two latter clocks, but
the main MMC one is unchanged.

We can adjust the phase with a 3 bits value, from 0 to 7, 0 meaning a 180 phase
shift, and the other values being the number of periods from the MMC parent
clock to outphase the clock of.

601da9d0a5 clk: sunxi: factors: Invert the probing logic
Until now, the factors clock probing was done directly by sunxi_init_clocks,
with the factors registration being called directly with the clocks data passed
as an argument.

This approch has shown its limits when we added more clocks, since we couldn't
really split code with such a logic in smaller files, and led to a huge file
having all the clocks.

Introduce an intermediate probing function, so that factor clocks will be able
to directly be called by CLK_OF_DECLARE, which will in turn ease the split into
several files.

9824cf73c3 clk: Add a function to retrieve phase
The current phase API doesn't look into the actual hardware to get the phase
value, but will rather get it from a variable only set by the set_phase
function.

This will cause issue when the client driver will never call the set_phase
function, where we can end up having a reported phase that will not match what
the hardware has been programmed to by the bootloader or what phase is
programmed out of reset.

Add a new get_phase function for the drivers to implement so that we can get
this value.

2c80929c4c fuse: honour max_read and max_write in direct_io mode
The third argument of fuse_get_user_pages() "nbytesp" refers to the number of
bytes a caller asked to pack into fuse request. This value may be lesser
than capacity of fuse request or iov_iter.  So fuse_get_user_pages() must
ensure that *nbytesp won't grow.

Now, when helper iov_iter_get_pages() performs all hard work of extracting
pages from iov_iter, it can be done by passing properly calculated
"maxsize" to the helper.

The other caller of iov_iter_get_pages() (dio_refill_pages()) doesn't need
this capability, so pass LONG_MAX as the maxsize argument here.

Fixes: c9c37e2e63 ("fuse: switch to iov_iter_get_pages()")

21e4b0726d rtlwifi: rtl8821ae: Move driver from staging to regular tree
This driver was entered into staging a few cycles ago because there was
not time to integrate the Realtek version into the support routines in
the kernel. Now that there is an effort to converg the code base from Linux
and the Realtek repo, it is time to move this driver. In addition, all the
updates included in the 06/28/2014 version of the Realtek drivers are
included here.

With this change, it will be necessary to delete the staging driver. That
will be handled in a separate patch. As it impacts the staging tree, such a
patch is sent to a different destination.

c151aed6aa rtlwifi: rtl8188ee: Update driver to match Realtek release of 06282014
Not only does this patch update the driver to match the latest Realtek release,
it is an important step in getting the internal code source at Realtek to match
the code in the kernel. The primary reason for this is to make it easier for
Realtek to maintain the kernel source without requiring an intermediate like me.

In this process of merging the two source repositories, there are a lot
of changes in both, and this commit is rather large.
