So there's no need to have a MODULE_ALIAS("platform:meson-rng") since
the reported uevent MODALIAS to user-space will always be the OF one.

Use the new API to create and destroy the crypto engine kthread
worker. The API hides some implementation details.
In particular, kthread_create_worker() allocates and initializes
struct kthread_worker. It runs the kthread the right way
and stores task_struct into the worker structure.
kthread_destroy_worker() flushes all pending works, stops
the kthread and frees the structure.
This patch does not change the existing behavior except for
dynamically allocating struct kthread_worker and storing
only the pointer of this structure.
It is compile tested only because I did not find an easy
way how to run the code. Well, it should be pretty safe
given the nature of the change.

The AES implementation using pure NEON instructions relies on the generic

we should refer to these round keys using 4x4 loads rather than 16x1 loads.
In addition, the ShiftRows tables are loading using a single scalar load,
which is also affected by endianness, so emit these tables in the correct

Currently, the driver breaks chain for all kind of hash requests in order to
don't override intermediate states of partial ahash updates. However, some final
ahash requests can be directly processed by the engine, and so without
intermediate state. This is typically the case for most for the HMAC requests
processed via IPSec.
This commits adds a TDMA descriptor to copy context for these of requests
into the "op" dma pool, then it allow to chain these requests at the DMA level.
The 'complete' operation is also updated to retrieve the MAC digest from the

So far, we used a dedicated dma pool to copy the result of outer IV for
cipher requests. Instead of using a dma pool per outer data, we prefer
use the op dma pool that contains all part of the request from the SRAM.
Then, the outer data that is likely to be used by the 'complete'
operation, is copied later. In this way, any type of result can be
retrieved by DMA for cipher or ahash requests.

The omap-rng driver currently assumes that there will only ever be a
single instance of an RNG device. For this reason, there is a statically
allocated struct hwrng, with a fixed name. However, registering two
struct hwrng with the same isn't accepted by the RNG framework, so we
need to switch to a dynamically allocated struct hwrng, each using a
different name. Then, we define the name of this hwrng to "dev_name(dev)",
so the name of the data structure is unique per device.

The ".data_present" and ".data_read" operations are marked as OBSOLETE
in the hwrng API. We have to use the ".read" operation instead. It makes
the driver simpler and moves the busy loop, that waits until enough data
is generated, to the read function. We simplify this step by only
checking the status of the engine, if there is data, we copy the data to
the output buffer and the amout of copied data is returned to the caller,
otherwise zero is returned. The hwrng core will re-call the read operation
as many times as required until enough data has been copied.

Pull cifs fixes from Steve French:
"Including:
- nine bug fixes for stable. Some of these we found at the recent two
weeks of SMB3 test events/plugfests.
- significant improvements in reconnection (e.g. if server or network
crashes) especially when mounted with "persistenthandles" or to
server which advertises Continuous Availability on the share.
- a new mount option "idsfromsid" which improves POSIX compatibility
in some cases (when winbind not configured e.g.) by better (and
faster) fetching uid/gid from acl (when "cifsacl" mount option is
enabled). NB: we are almost complete work on "cifsacl" (querying
mode/uid/gid from ACL) for SMB3, but SMB3 support for cifsacl is
not included in this set.
- improved handling for SMB3 "credits" (even if server is buggy)
Still working on two sets of changes:
- cifsacl enablement for SMB3
- cleanup of RFC1001 length calculation (so we can handle encryption
and multichannel and RDMA)
And a couple of new bugs were reported recently (unrelated to above)
so will probably have another merge request next week"
* 'for-next' of git://git.samba.org/sfrench/cifs-2.6: (21 commits)
CIFS: Retrieve uid and gid from special sid if enabled
CIFS: Add new mount option to set owner uid and gid from special sids in acl

Expose cifs module parameters in sysfs
Cleanup missing frees on some ioctls
Enable previous version support
Do not send SMB3 SET_INFO request if nothing is changing

Set previous session id correctly on SMB3 reconnect
cifs: Limit the overall credit acquired
Display number of credits available
Add way to query creation time of file via cifs xattr

Pull btrfs fixes from Chris Mason:
"Some fixes from Omar and Dave Sterba for our new free space tree.
This isn't heavily used yet, but as we move toward making it the new
default we wanted to nail down an endian bug"

btrfs: tests: uninline member definitions in free_space_extent

sb_wait_write()->percpu_rwsem_release() fools lockdep to avoid the
false-positives. Now that xfs was fixed by Dave's commit dbad7c9930
("xfs: stop holding ILOCK over filldir callbacks") we can remove it and
change freeze_super() and thaw_super() to run with s_writers.rw_sem locks
held; we add two trivial helpers for that, lockdep_sb_freeze_release()
and lockdep_sb_freeze_acquire().
xfstests-dev/check `grep -il freeze tests/*/???` does not trigger any
warning from lockdep.
