* mm + fs: store shadow entries in page cacheJohannes Weiner2014-04-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reclaim will be leaving shadow entries in the page cache radix tree upon evicting the real page. As those pages are found from the LRU, an iput() can lead to the inode being freed concurrently. At this point, reclaim must no longer install shadow pages because the inode freeing code needs to ensure the page tree is really empty. Add an address_space flag, AS_EXITING, that the inode freeing code sets under the tree lock before doing the final truncate. Reclaim will check for this flag before installing shadow pages.

| * crypto: mxs-dcp - Optimize hashingMarek Vasut2014-03-101-11/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimize the hashing operation in the MXS-DCP by doing two adjustments: 1) Given that the output buffer for the hash is now always correctly aligned, we can just use the buffer for the DCP DMA to store the resulting hash. We thus get rid of one copying of data. Moreover, we remove an entry from dcp_coherent_block{} and thus lower the memory footprint of the driver. 2) We map the output buffer for the hash for DMA only in case we will output the hash, not always, as it was now.

| | | | | | | | | | | | | | | | | | | | | | | | There are some suspicious looking lines of code in the new ccp driver, including one that assigns a variable to itself, and another that overwrites a previous assignment. This may have been a cut-and-paste error where 'src' was forgotten to be changed to 'dst'. I have no hardware to test this, so this is untested.

| | | | | | | | | | | | | | | | | | | | | | | | | | The SEC Controller driver creates platform devices for it's child job ring nodes. Currently the driver uses for_each_compatible routine which traverses the whole device tree to create the job rings for the platform device. The patch changes this to search for the compatible property of job ring only in the child nodes i.e., the job rings are created as per the number of children associated with the crypto node.

| * crypto: dcp - Move the AES operation type from actx to rctxMarek Vasut2014-02-091-10/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the AES operation type and mode from async crypto context to crypto request context. This allows for recycling of the async crypto context for different kinds of operations. I found this problem when I used dm-crypt, which uses the same async crypto context (actx) for both encryption and decryption requests. Since the requests are enqueued into the processing queue, immediatelly storing the type of operation into async crypto context (actx) caused corruption of this information when encryption and decryption operations followed imediatelly one after the other. When the first operation was dequeued, the second operation was already enqueued and overwritten the type of operation in actx, thus causing incorrect result of the first operation. Fix this problem by storing the type of operation into the crypto request context. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David S.

Bjorn Van Tilt contributes a patch which fixes a memory leak in usb_8dev's usb_8dev_start_xmit()s error path. A patch by Robert Schwebel fixes a typo in the can documentation. The remaining patches all target the c_can driver. Two of them are by me; they add a missing netif_napi_del() and return value checking. Thomas Gleixner contributes 12 patches, which address several shortcomings in the driver like hardware initialisation, concurrency, message ordering and poor performance. ==================== Signed-off-by: David S.
