2014-03-21Merge branch 'ptp-next'David S. Miller
Richard Cochran says: ==================== ptp: dynamic pin control This patch series introduces a way of changing the auxiliary PTP Hardware Clock functions (periodic output signals and time stamping external signals) at run time. In the past on the netdev list, we have discussed other ways to handle this, such as module parameters and ethtool. This series implements a new PHC ioctl because that is the most natural way. Users already activate the auxiliary functions via the ioctls. The sysfs interface has also been expanded so that the pin configuration can be programmed using shell scripts. The first patch adds the new ioctls. The PHC subsystem does most of the work of maintaining the function-to-pin mapping. Drivers will only need to allocate and initialize a pin configuration table and also provide a new method that validates a particular assignment. Patches 5 and 6 just clean up a couple of issues in the phyter driver, and the remaining patches actually hook the phyter's pins into the new system. * ChangeLog ** V3 - simplify locking in the set pin logic ** V2 - fix bug in sysfs code on init error path - rename ptp_setpin() to ptp_set_pinfunc() - rename .setpin() to .verify() in the driver interface - simplify ptp_find_pin() logic - use correct test when checking whether the pin with the calibration function is being reprogrammed ==================== Signed-off-by: David S.

2014-03-21ASoC: mfld_machine: Convert to table based DAPM and control setupLars-Peter Clausen
Use table based setup to register the controls and DAPM widgets and routes. This on one hand makes the code a bit cleaner and on the other hand the board level DAPM elements get registered in the card's DAPM context rather than in the CODEC's DAPM context. The mfld_machine driver is a bit special in that it directly writes to one of the CODEC registers from one of the control handlers. Previous to this patch it was able to get a pointer to the CODEC from the control, since the control was registered with the CODEC. This won't be possible anymore once the control is registered with the card. Since there are already global variables in the driver accessed in the same function the patch adds a global variable that holds a pointer to the CODEC and uses that.

I've been working on USB for seven years at Intel, and it's time for a change of pace. I'm pleased to announce that I'll be joining the Intel OTC ChromeOS team, where I'll get to learn and play with everything across the entire Linux stack, from kernel to graphics to browser technologies. (I'm a secret adventure/indie/casual gamer, so I'm super excited to start working on graphics features for ChromeOS.) I'm leaving the xHCI driver in Mathias Nyman's capable hands. I'll still be around to answer any architectural questions or triage really tough bugs, but I expect to ramp down on xHCI driver work in the coming weeks. I'll be available to answer xHCI questions until I start my 8-week sabbatical on May 8th. I'll be doing a National Parks road trip, and it's unlikely I'll have cell coverage. And, let's face it, people are supposed to ignore work email on sabbaticals. :) After my sabbatical ends on July 7th, I'll be focusing my time fully on ChromeOS. It's been great working with and learning from Greg, Alan, Oliver, and Felipe, but it's time to move onto my next adventure.

2014-03-21Revert "tracing: Move event storage for array from macro to standalone function"Steven Rostedt (Red Hat)
I originally wrote commit 35bb4399bd0e to shrink the size of the overhead of tracepoints by several kilobytes. Later, I received a patch from Vaibhav Nagarnaik that fixed a bug in the same code that this commit touches. Not only did it fix a bug, it also removed code and shrunk the size of the overhead of trace events even more than this commit did. Since this commit is scheduled for 3.15 and Vaibhav's patch is already in mainline, I need to revert this patch in order to keep it from conflicting with Vaibhav's patch. Not to mention, Vaibhav's patch makes this patch obsolete.

2014-03-21xhci: Transition maintainership to Mathias Nyman.Sarah Sharp
I'm transitioning maintainership of the xHCI driver to my colleague, Mathias Nyman. The xHCI driver is in good shape, and it's time for me to move on to the next shiny thing. :) There's a few known outstanding bugs that we have plans for how to fix: 1. Clear Halt issue that means some USB scanners fail after one scan 2. TD fragment issue that means USB ethernet scatter-gather doesn't work 3. xHCI command queue issues that cause the driver to die when a USB device doesn't respond to a Set Address control transfer when another command is outstanding. 4. USB port power off for Haswell-ULT is a complete disaster. Mathias is putting the finishing touches on a fix for #3, which will make it much easier to craft a solution for #1. Dan William has an ACKed RFC for #4 that may land in 3.16, after much testing. I'm working with Mathias to come up with an architectural solution for #2. I don't foresee very many big features coming down the pipe for USB (which is part of the reason it's a good time to change now). SSIC is mostly a hardware-level change (perhaps with some PHY drivers needed), USB 3.1 is again mostly a hardware-level change with some software engineering to communicate the speed increase to the device drivers, add new device descriptor parsing to lsusb, but definitely nothing as big as USB 3.0 was.

2014-03-21crypto: sha - SHA1 transform x86_64 AVX2chandramouli narayanan
This git patch adds x86_64 AVX2 optimization of SHA1 transform to crypto support. The patch has been tested with 3.14.0-rc1 kernel. On a Haswell desktop, with turbo disabled and all cpus running at maximum frequency, tcrypt shows AVX2 performance improvement from 3% for 256 bytes update to 16% for 1024 bytes update over AVX implementation. This patch adds sha1_avx2_transform(), the glue, build and configuration changes needed for AVX2 optimization of SHA1 transform to crypto support. sha1-ssse3 is one module which adds the necessary optimization support (SSSE3/AVX/AVX2) for the low-level SHA1 transform function. With better optimization support, transform function is overridden as the case may be. In the case of AVX2, due to performance reasons across datablock sizes, the AVX or AVX2 transform function is used at run-time as it suits best. The Makefile change therefore appends the necessary objects to the linkage. Due to this, the patch merely appends AVX2 transform to the existing build mix and Kconfig support and leaves the configuration build support as is.

2014-03-21crypto: caam - remove error propagation handlingHoria Geanta
Commit 61bb86bba169507a5f223b94b9176c32c84b4721 ("crypto: caam - set descriptor sharing type to SERIAL") changed the descriptor sharing mode from SHARE_WAIT to SHARE_SERIAL. All descriptor commands that handle the "ok to share" and "error propagation" settings should also go away, since they have no meaning for SHARE_SERIAL.

2014-03-21crypto: hash - Simplify the ahash_finup implementationMarek Vasut
The ahash_def_finup() can make use of the request save/restore functions, thus make it so. This simplifies the code a little and unifies the code paths. Note that the same remark about free()ing the req->priv applies here, the req->priv can only be free()'d after the original request was restored. Finally, squash a bug in the invocation of completion in the ASYNC path. In both ahash_def_finup_done{1,2}, the function areq->base.complete(X, err); was called with X=areq->base.data . This is incorrect , as X=&areq->base is the correct value. By analysis of the data structures, we see the areq is of type 'struct ahash_request' , areq->base is of type 'struct crypto_async_request' and areq->base.completion is of type crypto_completion_t, which is defined in include/linux/crypto.h as: typedef void (*crypto_completion_t)(struct crypto_async_request *req, int err); This is one lead that the X should be &areq->base . Next up, we can inspect other code which calls the completion callback to give us kind-of statistical idea of how this callback is used. We can try: $ git grep base\.complete\( drivers/crypto/ Finally, by inspecting ahash_request_set_callback() implementation defined in include/crypto/hash.h , we observe that the .data entry of 'struct crypto_async_request' is intended for arbitrary data, not for completion argument.

2014-03-21crypto: hash - Pull out the functions to save/restore requestMarek Vasut
The functions to save original request within a newly adjusted request and it's counterpart to restore the original request can be re-used by more code in the crypto/ahash.c file. Pull these functions out from the code so they're available. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David S.
