Some lines used spaces instead of tabs at line start.
This can cause mangled lines in editors due to inconsistency.

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!]
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.

That's a full tree sweep on my laptop. 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.

Quite some files have been flagged with the new GPL-2.0-only and
GPL-2.0-or-later identifiers which replace the original GPL-2.0 and
GPL-2.0+ identifiers in the SPDX license identifier specification, but the
identifiers are not mentioned as valid in the GPL-2.0 license file.
Add them to the license file and to the Linux-syscall-note exception to
make everything consistent again.

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.
