2017-10-12documentation: Update ide-cd documentation to reflect CONFIG_BLK_DEV_HD_IDE ↵Finn Thain
removal CONFIG_BLK_DEV_HD_IDE was removed in commit 80aa31cb460d ("ide: remove CONFIG_BLK_DEV_HD_IDE config option (take 2)") but the ide-cd documentation was not updated and still asks users to disable it, which is misleading and involves a fruitless search.

2017-10-12Merge branch 'refs' into docs-nextJonathan Corbet
Tom Saeger says: Recently, while reading up on binfmt I attempted to open a document ref only to find it was invalid. I did a quick grep, found all the binfmt_misc related broken refs and sent a patch. Fine. Easy. Then I wondered, "how many broken doc refs are there?". Turns out with all the recent doc moves, quite a few. I went about fixing just those found in Documentation/, except those in Documentation/translations/ and Documentation/devicetree/ for now. Most of these changes were s/txt/rst/ or fixing up a path to an obvious new location. Some required going back to v4.10 v4.4 or some other version to sleuth-out what content was actually being referenced and then fixing the reference to point to the new file with that content.

2017-10-12Documentation: add script and build target to check for broken file referencesJani Nikula
Add a simple script and build target to do a treewide grep for references to files under Documentation, and report the non-existing file in stderr. It tries to take into account punctuation not part of the filename, and wildcards, but there are bound to be false positives too. Mostly seems accurate though.

2017-10-07Documentation: add Kernel Driver Statement to the kernelGreg Kroah-Hartman
Way back in 2008 we didn't have "robust" in-kernel documentation system, so the idea of putting something like the kernel driver statement in the kernel tree wasn't even imagined. But now that has changed, so add the old document to the kernel source itself to allow for us to properly reference it in one canonical place (as the LF wiki keeps moving things around.) This also will allow people to add their names to it, as I seem to have lost the ability to do that by not knowing how to edit things on the original document.

2017-09-23tpm: ibmvtpm: simplify crq initialization and document crq formatMichal Suchanek
The crq is passed in registers and is the same on BE and LE hosts. However, current implementation allocates a structure on-stack to represent the crq, initializes the members swapping them to BE, and loads the structure swapping it from BE. This is pointless and causes GCC warnings about ununitialized members. Get rid of the structure and the warnings.

2017-09-23tpm: replace msleep() with usleep_range() in TPM 1.2/2.0 generic driversHamza Attak
The patch simply replaces all msleep function calls with usleep_range calls in the generic drivers. Tested with an Infineon TPM 1.2, using the generic tpm-tis module, for a thousand PCR extends, we see results going from 1m57s unpatched to 40s with the new patch. We obtain similar results when using the original and patched tpm_infineon driver, which is also part of the patch. Similarly with a STM TPM 2.0, using the CRB driver, it takes about 20ms per extend unpatched and around 7ms with the new patch. Note that the PCR consistency is untouched with this patch, each TPM has been tested with 10 million extends and the aggregated PCR value is continuously verified to be correct. As an extension of this work, this could potentially and easily be applied to other vendor's drivers. Still, these changes are not included in the proposed patch as they are untested.
