2016-08-24ftrace: Add return address pointer to ftrace_ret_stackJosh Poimboeuf
Storing this value will help prevent unwinders from getting out of sync with the function graph tracer ret_stack. Now instead of needing a stateful iterator, they can compare the return address pointer to find the right ret_stack entry. Note that an array of 50 ftrace_ret_stack structs is allocated for every task. So when an arch implements this, it will add either 200 or 400 bytes of memory usage per task (depending on whether it's a 32-bit or 64-bit platform).

2016-08-23scsi: cxlflash: Transition to application close modelMatthew R. Ochs
Caching the adapter file descriptor and performing a close on behalf of an application is a poor design. This is due to the fact that once a file descriptor in installed, it is free to be altered without the knowledge of the cxlflash driver. This can lead to inconsistencies between the application and kernel. Furthermore, the nature of the former design is more exploitable and thus should be abandoned. To support applications performing a close on the adapter file that is associated with a context, a new flag is introduced to the user API to indicate to applications that they are responsible for the close following the cleanup (detach) of a context. The documentation is also updated to reflect this change in behavior. Inspired-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Matthew R. Ochs <mrochs@linux.vnet.ibm.com> Acked-by: Manoj N.

In reality it doesn't work, but instead returns the same for the upper and lower bytes (nice catch from Alison!) * kxsd9 - Fix raw read return value to ensure it actually reports the value rather than a blank string. * max44000 - Missing buffer selects in Kconfig * rockchip_saradc - Add use of reset controller to enforce a clean state of the ADC. Some bootloaders can leave it in an 'intersting' state and effectively frozen without this. A couple of associated dts updates. * stk8ba50 - Missing buffer selects in Kconfig * stx104 - Fix a possible race due to use of devm_iio_device_register when there was other stuff in the remove function.

2016-08-23drm/fb-helper: Fix the dummy remove_conflicting_framebuffersChris Wilson
We always need to remove conflicting framebuffers if any other fb driver is enabled, and not just if we are setting up an fbdev ourselves. Unfortunately remove_conflicting_framebuffers() was incorrectly stubbed out if !fbdev rather than !fb leading to major memory corruption (and corrupt filesystems) upon boot.

2016-08-22qed*: Add support for VFs over legacy PFsYuval Mintz
Modern VFs can't run on old non-compatible as the fastpath HSI is slightly changed - but as the HSI is actually very close [basically, a single bit whose meaning flipped] this can be supported with small modifications. The major differences would be in: - Recognizing that VF is running on top of a legacy PF. - Returning some slowpath configurations that are no longer needed on top of modern PFs, but would be required when working over the legacy ones.

2016-08-22ASoC: uapi: Intel: Skylake: Define vendor specific tokensShreyas NC
With recent topology changes in alsa-lib, driver data for modules can now be passed in topology conf file using tuples. This patch defines vendor specific tokens to describe private data with tuples. The allowed token types are UUID, string, bool, byte, short and word. These tokens will be referenced by the vendor tuples in the conf file. In the topology conf file, multiple data blocks can be defined for a widget which can be either tuple vendor array or blob. So, each data block will be preceded by a descriptor to identify size and type of block. These descriptors will be token value pairs. Tokens for module_id and loadable flag are not defined as these are read from the DSP FW manifest.
