2016-03-23input: synaptics_dsx_core: clear all outstanding completionsHimanshu Aggarwal
The secure touch ISR and the poll logic in the user space layer is going out of sync because the completion lock in the driver is getting released in some corner cases unexpectedly. Clear all outstanding completions before waiting for one helps fix the issue. Change-Id: Ia3a6d318330263e7bfd8dfc3cea71c5300ab82b4 Signed-off-by: Himanshu Aggarwal <haggarwa@codeaurora.org>

2016-03-23input: synaptics_dsx_fw_update: modify firmware upgrade procedureHimanshu Aggarwal
Modify the firmware upgrade procedure based on the following requirements: If config id of the firmware file is greater than the config id in the device and if packrat id of the firmware img file is greater than the firmware build id in the device, then during the firmware upgrade procedure, both firmware and config areas are upgraded. Otherwise, if the packrat id of the firmware img file is equal to the firmware build id in the device, then only the config area is upgraded. However, if the packrat id of the firmware img file is lesser than the firmware build id in the device, then it is considered as an error. Similarly, if config id of the firmware file is equal to the config id in the device and if packrat id of the firmware img file is greater than the firmware build id in the device, then during the firmware upgrade procedure, both firmware and config areas are upgraded. Otherwise, if the packrat id of the firmware img file is equal to the firmware build id in the device, then no upgrade is needed. However, if the packrat id of the firmware img file is lesser than the firmware build id in the device, then it is considered as an error. This is a propagated patch from 3.10 kernel commit - d9921ff0ce4024b43837d794cc261b52ae58f776 , input: synaptics_dsx_fw_update: modify firmware upgrade procedure Change-Id: I646d2c04243a30b77d48698cce76e9e183bd6db1 Signed-off-by: Himanshu Aggarwal <haggarwa@codeaurora.org>

2016-03-23soc: qcom: Add kernel_protect library and initcallMitchel Humpherys
It's good security practice to make your executable code read-only. On hypervisor-enabled targets, this can be trivially accomplished by removing the writable attribute from all stage-2 mappings of the kernel text. Add a small library and initcall to do this. Due to constraints on the hypervisor, this needs to happen before all of the cores are brought out of reset, so make it an early_initcall.

2016-03-23scripts: Restore some of the parallism in "all" buildsDavid Brown
The use of min/max should not have been switched, and instead of forcing at least "-j2" for builds, it is enforcing no more than two jobs in parallel. This has drastically reduced the parallelism of the builds. Change this to use "max" as intended so that we do make use of available CPUs, using at least two.

2016-03-23scripts: Reduce parallelism in "all" buildsDavid Brown
Kernel builds are a bit asymmetrical in as far as CPU and memory resources go. Compilation itself tends to scale fairly linearly in RAM usage per number of CPUs. However, the link phase tends to use a fairly constant large amount of RAM and generally only one CPU. The existing attempt to build more in parallel has mostly resulted in too many link steps running, which ends up swapping. Instead of dividing the CPUs by the number of targets, just divide it by two, and assume this will at least get us some compilation happening during the link phase of one target build.

2016-03-23setlocalversion: Include post Linus git tags in LOCALVERSION_AUTOStephen Boyd
The localversion detection script assumes that if there's a tag describing the commit the toplevel Makefile would indicate what that version is. This is usually true because Linus tags a commit and updates the Makefile at the same time to make a release. Unfortunately this means that any other tags made on the kernel are ignored and not used in the localversion output. For example, consider Linus tagged v3.0-rc5 and I have worked on a bunch of commits based off that tag and then tagged my branch with another tag called "changes-for-linus". Ideally I would like to see the kernel is based off v3.0-rc5 at the tag changes-for-linus. When localversion detects the version it assumes that the kernel is v3.0-rc5 because a tag is on the current commit but it doesn't confirm that the tag matches the Makefile. It then proceeds to throw away everything after the patch level and git commit hash from git describe output so we lost the tag changes-for-linus and are left with: v3.0-rc5-0003-g234ad Instead of doing that always try to describe the tree regardless of whether or not there is an exact match (unless we are doing --short output and just want to put a + after the version). Include the hash of the tag so that we get a bit more information about the tree that was built, but be sure to throw away any tags from Linus himself that start with v3.* so that we get output like: v3.0-rc5-g1561da-linus-0003-g234ad Change-Id: I9c4d03c61650658676f221680c61899305c6217a Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

Improve parsing of multiline macros which run beyond the available diff context. These beyond-the-horizon macros previously caused two distinct naughty behaviors: - The scanner, confused by the trailing backslash, would grab the header of the next context hunk and treat it as the last line of the preceding macro. - The analyzer, unable to fully reduce the macro, would blame the patch for submitting an unbalanced or unprotected macro.

2016-03-23checkpatch: deprecate unbounded string functions.Gregory Bean
Unbounded string functions are overflow risks. The 'n' versions of those functions should be used instead.

2016-03-23checkpatch: forbid implied-barrier I/O functions.Gregory Bean
Forbid read[bwl], write[bwl], in[bwl], and out[bwl], as they contain a 'stealth barrier' which can harm performance. Developers are expected to call appropriate __raw_* or *_relaxed APIs and manage barriers explicitly.
