2020-09-10.gitignore: docs: ignore sphinx_*/ directoriesMauro Carvalho Chehab
The default way of building documentation is to use Sphinx toolchain installed via pip, inside the Kernel tree main directory. That's what's recommended by: scripts/sphinx-pre-install As it usually provides a better version of this package than the one installed, specially on LTS distros. So, add the directories created by running the commands suggested by the script.

2020-09-03docs: Add automatic cross-reference for C typesNícolas F. R. A. Prado
In order to cross-reference C types in the documentation, Sphinx requires the syntax :c:type:`type_name`, or even :c:type:`struct type_name <type_name>` in order to have the link text different from the target text. Extend automarkup to enable automatic cross-reference of C types by matching any "struct|union|enum|typedef type_name" expression. This makes the documentation's plain text cleaner and adds cross-reference to types without any additional effort by the author. Signed-off-by: Nícolas F. R. A.

2020-08-31Documentation: clarify driver licensing rulesDave Hansen
Greg has challenged some recent driver submitters on their license choices. He was correct to do so, as the choices in these instances did not always advance the aims of the submitters. But, this left submitters (and the folks who help them pick licenses) a bit confused. They have read things like Documentation/process/license-rules.rst which says: individual source files can have a different license which is required to be compatible with the GPL-2.0 and Documentation/process/submitting-drivers.rst: We don't insist on any kind of exclusive GPL licensing, and if you wish ... you may well wish to release under multiple licenses. As written, these appear a _bit_ more laissez faire than we've been in practice lately. It sounds like we at least expect submitters to make a well-reasoned license choice and to explain their rationale. It does not appear that we blindly accept anything that is simply GPLv2-compatible. Drivers appear to be the most acute source of misunderstanding, so fix the driver documentation first. Update it to clarify expectations.

2020-08-31Documentation: add minimum clang/llvm versionNick Desaulniers
Based on a vote at the LLVM BoF at Plumbers 2020, we decided to start small, supporting just one formal upstream release of LLVM for now. We can probably widen the support window of supported versions over time. Also, note that LLVM's release process is different than GCC's. GCC tends to have 1 major release per year while releasing minor updates to the past 3 major versions. LLVM tends to support one major release and one minor release every six months.

Pull io_uring fixes from Jens Axboe: "A few differerent things in here. Seems like syzbot got some more io_uring bits wired up, and we got a handful of reports and the associated fixes are in here. General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads. Some applications don't really like that, so the io_read() code now handles short reads internally, and got a cleanup along the way so that it's now easier to read (and documented). We're now passing tests that failed before" * tag 'io_uring-5.9-2020-08-15' of git://git.kernel.dk/linux-block: io_uring: short circuit -EAGAIN for blocking read attempt io_uring: sanitize double poll handling io_uring: internally retry short reads io_uring: retain iov_iter state over io_read/io_write calls task_work: only grab task signal lock when needed io_uring: enable lookup of links holding inflight files io_uring: fail poll arm on queue proc failure io_uring: hold 'ctx' reference around task_work queue + execute fs: RWF_NOWAIT should imply IOCB_NOIO io_uring: defer file table grabbing request cleanup for locked requests io_uring: add missing REQ_F_COMP_LOCKED for nested requests io_uring: fix recursive completion locking on oveflow flush io_uring: use TWA_SIGNAL for task_work uncondtionally io_uring: account locked memory before potential error case io_uring: set ctx sq/cq entry count earlier io_uring: Fix NULL pointer dereference in loop_rw_iter() io_uring: add comments on how the async buffered read retry works io_uring: io_async_buf_func() need not test page bit
2020-08-16parisc: fix PMD pages allocation by restoring pmd_alloc_one()Mike Rapoport
Commit 1355c31eeb7e ("asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()") converted parisc to use generic version of pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for PMD. Restore the original version of pmd_alloc_one() for parisc, just use GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and memset.
