2018-04-27docs/vm: pagemap: change document titleMike Rapoport1-3/+3
"pagemap from the Userspace Perspective" is not very descriptive for unaware readers. Since the document describes how to examine a process page tables, let's title it "Examining Process Page Tables" Signed-off-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2018-04-27docs/vm: hugetlbpage: move section about kernel development to hugetlbfs_reservMike Rapoport2-8/+8
The hugetlbpage describes hugetlbfs from the user perspective and newer hugetlbfs_reserv document targets kernel developers. Hence the section about hugetlbfs kernel development naturally belongs there. Signed-off-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2018-04-27Merge branch 'tglx-license' into docs-nextJonathan Corbet8-1/+1298
Thomas said: There are a few bogus SPDX identifiers in various files and SPDX Identifiers used in tree or about to be used which have no corresponding License Text file in the LICENSES directory or use the new variant of the GPL-2.0[+] license identifiers which are not mentioned in the GPL-2.0 Valid-License-Identifiers: tags. There is no tool which can be used to scan the tree and also nothing which helps people who submit patches to check their stuff before submission. The following series cleans that up: - Add GPL-2.0-only and GPL-2.0-or-later identifiers to the GPL2.0 license and the Linux-syscall-note exception - Add X11, Apache-2.0, CC-BY-SA-4.0, CCDL-1.0, Linux-OpenIB license texts to the LICENSES directory along with the required documentation texts - Add a checker script which can read a single file or even a patch from the command line or does a full git tree scan [Thomas also wins some sort of special prize for including an SPDX-checking patch that complains about itself!]
2018-04-27scripts: Add SPDX checker scriptThomas Gleixner1-0/+284
The SPDX-License-Identifiers are growing in the kernel and so grow expression failures and license IDs are used which have no corresponding license text file in the LICENSES directory. Add a script which gathers information from the LICENSES directory, i.e. the various tags in the licenses and exception files and then scans either input from stdin, which it treats as a single file or if started without arguments it scans the full kernel tree. It checks whether the license expression syntax is correct and also validates whether the license identifiers used in the expressions are available in the LICENSES files. scripts/spdxcheck.py -h usage: spdxcheck.py [-h] [-m MAXLINES] [-v] [path [path ...]] SPDX expression checker positional arguments: path Check path or file. If not given full git tree scan. For stdin use "-" optional arguments: -h, --help show this help message and exit -m MAXLINES, --maxlines MAXLINES Maximum number of lines to scan in a file.

Note, this runs single threaded. It scans by default the first 15 lines for a SPDX identifier where the current max inside a top comment is at line 10. But that's going to be faster once the identifiers are all in the first two lines as documented. The python wizards will surely know how to do that smarter and faster, but its at least better than no tool at all.

2018-04-16Merge branch 'mm-rst' into docs-nextJonathan Corbet72-2211/+2610
Mike Rapoport says: These patches convert files in Documentation/vm to ReST format, add an initial index and link it to the top level documentation. There are no contents changes in the documentation, except few spelling fixes. The relatively large diffstat stems from the indentation and paragraph wrapping changes. I've tried to keep the formatting as consistent as possible, but I could miss some places that needed markup and add some markup where it was not necessary. [jc: significant conflicts in vm/hmm.rst]
