Falcon Ridge 4C has been supported by the driver from the beginning,
Falcon Ridge 2C support was just added. Don't irritate users with a
warning declaring the opposite.

The quirk 'quirk_apple_wait_for_thunderbolt' did not fire on Falcon
Ridge 4C controllers with subdevice/subvendor set to zero. This lead
to lost pci devices on system resume.
Older thunderbolt controllers (pre Falcon Ridge) used the same device id
for bridges and for the controller. On Apple hardware the subvendor- &
subdevice-ids were set for the controller, but not for bridges. So that
is what was used to differentiate between the two. Starting with Falcon
Ridge bridges and controllers received different device ids.
Additionally on some MacBookPro models (but not all) the
subvendor/subdevice was zeroed.
Starting with a42fb351c (thunderbolt: Allow loading of module on recent
Apple MacBooks with thunderbolt 2 controller) the thunderbolt driver
binds to all Falcon Ridge 4C controllers (irregardless of
subvendor/subdevice). The corresponding quirk was not updated.
This commit changes the quirk to check the device class instead of its
subvendor-/subdeviceids. This works for all generations of Thunderbolt
controllers.

lkdtm_rodata_do_nothing() is an empty function which is generated in
order to test the non-executability of rodata.
Currently if function tracing is enabled then an mcount callsite will be
generated for lkdtm_rodata_do_nothing(), and it will appear in the list
of available functions for function tracing (available_filter_functions).
Given it's purpose purely as a test function, it seems preferable for
lkdtm_rodata_do_nothing() to be marked notrace, so it doesn't appear as
traceable.
This also avoids triggering a linker bug on powerpc:
https://sourceware.org/bugzilla/show_bug.cgi?id=20428
When the linker sees code that needs to generate a call stub, eg. a
branch to mcount(), it assumes the section is executable and
dereferences a NULL pointer leading to a linker segfault. Marking
lkdtm_rodata_do_nothing() notrace avoids triggering the bug because the
function contains no other function calls.

Even if PR3 support is available on the bridge, it will not be used if
the PCI layer considers it unavailable (i.e. on all laptops from 2013
and 2014). Ensure that this condition is checked to allow a fallback to
the Optimus DSM for device poweroff.
Initially I wanted to call pci_d3cold_enable before checking bridge_d3
(in case the user changed d3cold_allowed), but that is such an unlikely
case and likely fragile anyway. The current patch is suggested by Mika
in http://www.spinics.net/lists/linux-pci/msg52599.html

The workqueue "dm_bufio_wq" queues a single work item &dm_bufio_work so
it doesn't require execution ordering. Hence, alloc_workqueue() has
been used to replace the deprecated create_singlethread_workqueue().
The WQ_MEM_RECLAIM flag has been set since DM requires forward progress
under memory pressure.
Since there are fixed number of work items, explicit concurrency
limit is unnecessary here.

If crypt_alloc_tfms() had to allocate multiple tfms and it failed before
the last allocation, then it would call crypt_free_tfms() and could free
pointers from uninitialized memory -- due to the crypt_free_tfms() check
for non-zero cc->tfms[i]. Fix by allocating zeroed memory.

When dm-crypt processes writes, it allocates a new bio in
crypt_alloc_buffer(). The bio is allocated from a bio set and it can
have at most BIO_MAX_PAGES vector entries, however the incoming bio can be
larger (e.g. if it was allocated by bcache). If the incoming bio is
larger, bio_alloc_bioset() fails and an error is returned.
To avoid the error, we test for a too large bio in the function
crypt_map() and use dm_accept_partial_bio() to split the bio.
dm_accept_partial_bio() trims the current bio to the desired size and
asks DM core to send another bio with the rest of the data.

bio_alloc() can allocate a bio with at most BIO_MAX_PAGES (256) vector
entries. However, the incoming bio may have more vector entries if it
was allocated by other means. For example, bcache submits bios with
more than BIO_MAX_PAGES entries. This results in bio_alloc() failure.
To avoid the failure, change the code so that it allocates bio with at
most BIO_MAX_PAGES entries. If the incoming bio has more entries,
bio_add_page() will fail and a new bio will be allocated - the code that
handles bio_add_page() failure already exists in the dm-log-writes
target.

Move log_one_block()'s atomic_inc(&lc->io_blocks) before bio_alloc() to
fix a bug that the target hangs if bio_alloc() fails. The error path
does put_io_block(lc), so atomic_inc(&lc->io_blocks) must occur before
invoking the error path to avoid underflow of lc->io_blocks.

We don't support configuring active plane on-the-fly for imx-drm.
The relevant CRTC should be disabled before the plane configuration.
Of course, the plane itself should be disabled as well.
This patch adds active plane reconfiguration support by forcing CRTC
mode change and disabling-enabling plane in plane's ->atomic_update
callback.

...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
We delete the MODULE_LICENSE tag etc. since all that information

Commit b70661c70830 ("net: smc91x: use run-time configuration on all ARM
machines") broke some ARM platforms through several mistakes. Firstly,
the access size must correspond to the following rule:
(a) at least one of 16-bit or 8-bit access size must be supported
(b) 32-bit accesses are optional, and may be enabled in addition to
the above.
Secondly, it provides no emulation of 16-bit accesses, instead blindly
making 16-bit accesses even when the platform specifies that only 8-bit
is supported.
Reorganise smc91x.h so we can make use of the existing 16-bit access
emulation already provided - if 16-bit accesses are supported, use
16-bit accesses directly, otherwise if 8-bit accesses are supported,
use the provided 16-bit access emulation. If neither, BUG(). This
exactly reflects the driver behaviour prior to the commit being fixed.
Since the conversion incorrectly cut down the available access sizes on
several platforms, we also need to go through every platform and fix up
the overly-restrictive access size: Arnd assumed that if a platform can
perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access
size needed to be specified - not so, all available access sizes must
be specified.
This likely fixes some performance regressions in doing this: if a
platform does not support 8-bit accesses, 8-bit accesses have been
emulated by performing a 16-bit read-modify-write access.
Tested on the Intel Assabet/Neponset platform, which supports only 8-bit
accesses, which was broken by the original commit.
