Pull crypto update from Herbert Xu:
 "Here is the crypto update for 4.2:

  API:

   - Convert RNG interface to new style.

   - New AEAD interface with one SG list for AD and plain/cipher text.
     All external AEAD users have been converted.

   - New asymmetric key interface (akcipher).

  Algorithms:

   - Chacha20, Poly1305 and RFC7539 support.

   - New RSA implementation.

   - Jitter RNG.

   - DRBG is now seeded with both /dev/random and Jitter RNG.  If kernel
     pool isn't ready then DRBG will be reseeded when it is.

   - DRBG is now the default crypto API RNG, replacing krng.

   - 842 compression (previously part of powerpc nx driver).

  Drivers:

   - Accelerated SHA-512 for arm64.

   - New Marvell CESA driver that supports DMA and more algorithms.

   - Updated powerpc nx 842 support.

   - Added support for SEC1 hardware to talitos"

mac802154: iface: cleanup stack variable

2015-06-17T14:00:40+00:00

There is no need to init res with zero, res can be unused but then we
returning zero and not res.

mac802154: iface: fix order while interface up

2015-06-17T14:00:40+00:00

This patch moves the hardware setting before calling the driver start
callback which activates the receive handling. The hardware setup
contains settings like address filtering which should be setup before
activate the receive handling on the transceiver. These setting are
protected by ieee802154_check_concurrent_iface check. This means we
need to set these registers once before calling drv_start and can't
be overwritten by other interfaces.

mac802154: iface: flush workqueue before stop

2015-06-14T23:22:19+00:00

This patch flushs the workqueue which is currently used for xmit_sync
callback before calling stop driver-ops. Flush the queue will ensure all
pending tx frames are transmitted.

mac802154: iface: fix hrtimer cancel on ifdown

2015-06-14T23:22:19+00:00

The interframe spacing timer is a per phy definition and is part of a
ieee802154_local structure. If we have possible multiple interfaces
ifdown one interface then the timer should not be cancled. First if the
last interface is down and the receive handling is stopped we should be
sure that the interframe spacing timer isn't run anymore.

mac802154/iface: remove superfluous WARN_ON call in slave_open()

2015-06-09T07:44:23+00:00

This call was used before we aligned our code with the wireless code base. We
are wanted to handle this in the err: code path. Which would actually not work
because the WARN_ON() macro would reset the res value to 0 and thus we would
never hit err:. Removing it makes the code do what we actually intend.

mac802154: remove unneeded vif struct

2015-06-07T07:13:32+00:00

This patch removes the virtual interface structure from sub if data
struct, because it isn't used anywhere. This structure could be useful
for give per interface information at softmac driver layer. Nevertheless
there exist no use case currently and it contains the interface type
information currently. This information is also stored inside wpan dev
which is now used to check on the wpan dev interface type.
