2017-04-25dm crypt: remove obsolete references to per-CPU stateEric Biggers
dm-crypt used to use separate crypto transforms for each CPU, but this is no longer the case. To avoid confusion, fix up obsolete comments and rename setup_essiv_cpu(). Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2017-04-25iwlwifi: adjust NVM parsing APIs for new a000 methodSara Sharon
In a000 devices we will get all nvm data from the firmware, and can save most of the parsing. Export two APIs that op mode will still use. Adjust API of init_sbands to be independent of NVM file structure so it can be used by op mode as well.

2017-04-25iwlwifi: pcie: apply no-reclaim logic only to group 0Johannes Berg
When applying no-reclaim logic to commands other than the group zero for legacy commands, commands such as 0x1c (TX_CMD in group 0) can't be used in any other group. Fix that by applying this logic only for group 0 - it's not and should never be needed for any other groups.

2017-04-25iwlwifi: rename wait_for_tx_queues_emptySara Sharon

2017-04-25iwlwifi: mvm: support station type APISara Sharon
Support change to ADD_STA API to support station types. Each station is assigned its type. This simplifies FW handling of the broadcast and multicast stations: * broadcast station is identified by its type and not the mac address. * multicast queue is no longer treated differently. The opening and closing of it is done by referring to its station. There is no need to specify it in the MAC command. * When disabling TX to all station driver can disable the traffic on multicast station, so FW doesn't have to do it. Change is backward compatible. Change the order of adding and removing the stations according to FW requirements. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-04-25iwlwifi: mvm: remove references to queue_info in new TX pathSara Sharon
Most of the fields aren't needed in new TX path. Enlarging the struct to 512 queues will consume a lot of memory. Remove all references to the struct in the new TX path.

2017-04-25iwlwifi: remove module loading failure messageJohannes Berg
When CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, iwlwifi crashes when the opmode module cannot be loaded, due to completing the completion before using drv->dev, which can then already be freed. Fix this by removing the (fairly useless) message. Moving the completion later causes a deadlock instead, so that's not an option.

2017-04-25iwlwifi: don't leak memory on allocation failureJohannes Berg
If we fail to allocate the small chunk of memory for the pieces of the firmware file, we leak the whole firmware image instead...

2017-04-25ceph: fix recursion between ceph_set_acl() and __ceph_setattr()Yan, Zheng
ceph_set_acl() calls __ceph_setattr() if the setacl operation needs to modify inode's i_mode. __ceph_setattr() updates inode's i_mode, then calls posix_acl_chmod(). The problem is that __ceph_setattr() calls posix_acl_chmod() before sending the setattr request. The get_acl() call in posix_acl_chmod() can trigger a getxattr request. The reply of the getxattr request can restore inode's i_mode to its old value. The set_acl() call in posix_acl_chmod() sees old value of inode's i_mode, so it calls __ceph_setattr() again.

It takes existing code in apollo, audptr and spkout which already fits the behaviour of send_xchar and tiocmset. In follow-up patches there will be TTY-based implementations of these methods.
