Pull Documentation updates from Jonathan Corbet: "Here are the main documentation changes for 5.5: - Various kerneldoc script enhancements. - More RST conversions; those are slowing down as we run out of things to convert, but we're a ways from done still. - Dan's "maintainer profile entry" work landed at last. Now we just need to get maintainers to fill in the profiles... - A reworking of the parallel build setup to work better with a variety of systems (and to not take over huge systems entirely in particular). - The MAINTAINERS file is now converted to RST during the build. Hopefully nobody ever tries to print this thing, or they will need to load a lot of paper. - A script and documentation making it easy for maintainers to add Link: tags at commit time. Also included is the removal of a bunch of spurious CR characters" * tag 'docs-5.5a' of git://git.lwn.net/linux: (91 commits) docs: remove a bunch of stray CRs docs: fix up the maintainer profile document libnvdimm, MAINTAINERS: Maintainer Entry Profile Maintainer Handbook: Maintainer Entry Profile MAINTAINERS: Reclaim the P: tag for Maintainer Entry Profile docs, parallelism: Rearrange how jobserver reservations are made docs, parallelism: Do not leak blocking mode to other readers docs, parallelism: Fix failure path and add comment Documentation: Remove bootmem_debug from kernel-parameters.txt Documentation: security: core.rst: fix warnings Documentation/process/howto/kokr: Update for 4.x -> 5.x versioning Documentation/translation: Use Korean for Korean translation title docs/memory-barriers.txt: Remove remaining references to mmiowb() docs/memory-barriers.txt/kokr: Update I/O section to be clearer about CPU vs thread docs/memory-barriers.txt/kokr: Fix style, spacing and grammar in I/O section Documentation/kokr: Kill all references to mmiowb() docs/memory-barriers.txt/kokr: Rewrite "KERNEL I/O BARRIER EFFECTS" section docs: Add initial documentation for devfreq Documentation: Document how to get links with git am docs: Add request_irq() documentation ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.5 kernel cycle Core changes: - Expose pull up/down flags for the GPIO character device to userspace. After clear input from the RaspberryPi and Beagle communities, it has been established that prototyping, industrial automation and make communities strongly need this feature, and as we want people to use the character device, we have implemented the simple pull up/down interface for GPIO lines. This means we can specify that a (chip-specific) pull up/down resistor can be enabled, but does not offer fine-grained control such as cases where the resistance of the same pull resistor can be controlled (yet). - Introduce devm_fwnode_gpiod_get_index() and start to phase out the old symbol devm_fwnode_get_index_gpiod_from_child(). - A bit of documentation clean-up work. - Introduce a define for GPIO line directions and deploy it in all GPIO drivers in the drivers/gpio directory. - Add a special callback to populate pin ranges when cooperating with the pin control subsystem and registering ranges as part of adding a gpiolib driver and a gpio_irq_chip driver at the same time. This is also deployed in the Intel Merrifield driver. New drivers: - RDA Micro GPIO controller. - XGS-iproc GPIO driver.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This merge window we have one small clk provider API in the core framework and then a bunch of driver updates and a handful of new drivers. In terms of diffstat the Qualcomm and Amlogic drivers are high up there because of all the clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work done this cycle too to support suspend/resume and memory controllers. And the OMAP clk driver got proper clk and reset handling in place. Rounding out the patches are various updates to remove unused data, mark things static, correct incorrect data in drivers, etc. All the little things that improve drivers and maintain code health. I will point out that there's a patch in here for the GPIO clk driver, that almost nobody uses, which changes behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent. Other than that things are fairly well SoC specific here.

If my analysis turns out to be wrong and someone actually cares it will be easy to revert this commit and have the system call again. There was one new xtensa defconfig in linux-next that enabled the system call this cycle and when asked about it the maintainer of the code replied that it was not enabled on purpose. As of today's linux-next tree that defconfig no longer enables the system call.

It was reported [0] that network doesn't wake up on cable plug-in with certain chip versions. Reason is that on these chip versions the PHY doesn't detect cable plug-in when being in power-down mode.

2019-12-01mm/page_io.c: annotate refault stalls from swap_readpageMinchan Kim1-2/+13
If a block device supports rw_page operation, it doesn't submit bios so the annotation in submit_bio() for refault stall doesn't work. It happens with zram in android, especially swap read path which could consume CPU cycle for decompress. It is also a problem for zswap which uses frontswap. Annotate swap_readpage() to account the synchronous IO overhead to prevent underreport memory pressure.

2019-12-01mm: shmem: use proper gfp flags for shmem_writepage()Yang Shi1-1/+2
The shmem_writepage() uses GFP_ATOMIC to allocate swap cache. GFP_ATOMIC used to mean __GFP_HIGH, but now it means __GFP_HIGH | __GFP_ATOMIC | __GFP_KSWAPD_RECLAIM. However, shmem_writepage() should write out to swap only in response to memory pressure, so __GFP_KSWAPD_RECLAIM looks useless since the caller may be kswapd itself or in direct reclaim already. In addition, XArray node allocations from PF_MEMALLOC contexts could completely exhaust the page allocator, __GFP_NOMEMALLOC stops emergency reserves from being allocated. Here just copy the gfp flags used by add_to_swap(). Hugh: "a cleanup to make the two calls look the same when they don't need to be different (whereas the call from __read_swap_cache_async() rightly uses a lower priority gfp)".

2019-12-01userfaultfd: require CAP_SYS_PTRACE for UFFD_FEATURE_EVENT_FORKMike Rapoport1-7/+11
A while ago Andy noticed (http://lkml.kernel.org/r/CALCETrWY+5ynDct7eU_nDUqx=okQvjm=Y5wJvA4ahBja=CQXGw@mail.gmail.com) that UFFD_FEATURE_EVENT_FORK used by an unprivileged user may have security implications. As the first step of the solution the following patch limits the availably of UFFD_FEATURE_EVENT_FORK only for those having CAP_SYS_PTRACE. The usage of CAP_SYS_PTRACE ensures compatibility with CRIU. Yet, if there are other users of non-cooperative userfaultfd that run without CAP_SYS_PTRACE, they would be broken :( Current implementation of UFFD_FEATURE_EVENT_FORK modifies the file descriptor table from the read() implementation of uffd, which may have security implications for unprivileged use of the userfaultfd. Limit availability of UFFD_FEATURE_EVENT_FORK only for callers that have CAP_SYS_PTRACE.
