Merge tag 'docs-for-linus' of git://git.lwn.net/linux-2.6
Pull documentation update from Jonathan Corbet: "Here's my set of accumulated documentation changes for 3.19. It includes a couple of additions to the coding style document, some fixes for minor build problems within the documentation tree, the relocation of the kselftest docs, and various tweaks and additions. A couple of changes reach outside of Documentation/; they only make trivial comment changes and I did my best to get the required acks. Complete with a shiny signed tag this time around" * tag 'docs-for-linus' of git://git.lwn.net/linux-2.6: kobject: grammar fix Input: xpad - update docs to reflect current state Documentation: Build mic/mpssd only for x86_64 cgroups: Documentation: fix wrong cgroupfs paths Documentation/email-clients.txt: add info about Claws Mail CodingStyle: add some more error handling guidelines kselftest: Move the docs to the Documentation dir Documentation: fix formatting to make 's' happy Documentation: power: Fix typo in Documentation/power Documentation: vm: Add 1GB large page support information ipv4: add kernel parameter tcpmhash_entries Documentation: Fix a typo in mailbox.txt treewide: Fix typo in Documentation/DocBook/device-drivers CodingStyle: Add a chapter on conditional compilation
