2019-07-17docs: powerpc: convert docs to ReST and rename to *.rstMauro Carvalho Chehab1-1/+1
Convert docs to ReST and add them to the arch-specific book. The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard. The changes were mostly to mark literal blocks and add a few missing section title identifiers. One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

Pull pidfd and clone3 fixes from Christian Brauner: "This contains a bugfix for CLONE_PIDFD when used with the legacy clone syscall, two fixes to ensure that syscall numbering and clone3 entrypoint implementations will stay consistent, and an update for the maintainers file: - The addition of clone3 broke CLONE_PIDFD for legacy clone on all architectures that use do_fork() directly instead of calling the clone syscall itself. (Fwiw, cleaning do_fork() up is on my todo.) The reason this happened was that during conversion of _do_fork() to use struct kernel_clone_args we missed that do_fork() is called directly by various architectures. This is fixed by making sure that the pidfd argument in struct kernel_clone_args is correctly initialized with the parent_tidptr argument passed down from do_fork(). Additionally, do_fork() missed a check to make CLONE_PIDFD and CLONE_PARENT_SETTID mutually exclusive just a clone() does. This is now fixed too. - When clone3() was introduced we skipped architectures that require special handling for fork-like syscalls. Their syscall tables did not contain any mention of clone3(). To make sure that Arnd's work to make syscall numbers on all architectures identical (minus alpha) was not for naught we are placing a comment in all syscall tables that do not yet implement clone3(). The comment makes it clear that 435 is reserved for clone3 and should not be used. - Also, this contains a patch to make the clone3() syscall definition in asm-generic/unist.h conditional on __ARCH_WANT_SYS_CLONE3. This lets us catch new architectures that implicitly make use of clone3 without setting __ARCH_WANT_SYS_CLONE3 which is a good indicator that they did not check whether it needs special treatment or not. - Finally, this contains a patch to add me as maintainer for pidfd stuff so people can start blaming me (more)" * tag 'for-linus-20190715' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: MAINTAINERS: add new entry for pidfd api unistd: protect clone3 via __ARCH_WANT_SYS_CLONE3 arch: mark syscall number 435 reserved for clone3 clone: fix CLONE_PIDFD support

2019-07-15docs: ioctl-number.txt: convert it to ReST formatMauro Carvalho Chehab1-1/+1
The conversion itself is simple: add a markup for the title of this file and add markups for both tables. Yet, the big table here with IOCTL numbers is badly formatted: on several lines, the "Include File" column has some values that are bigger than the reserved space there. Also, on several places, a comment was misplaced at the "Include File" space. So, most of the work here is to actually ensure that each field will be properly fixed. Also worth to mention that some URLs have the asterisk character on it. Well, Sphinx has an issue with asterisks in the middle of an string. As this is URL, use the alternate format: %2A. As a side effect of this patch, it is now a lot easier to see that some reserved ioctl numbers are missing the include files where it is supposed to be used. PS.: While this is part of a subdir, I opted to convert this single file alone, as this file has a potential of conflicts, as most subsystem maintainers touch it.

The remaining conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2019-07-15docs: locking: convert docs to ReST and rename to *.rstMauro Carvalho Chehab3-3/+3
Convert the locking documents to ReST and add them to the kernel development book where it belongs. Most of the stuff here is just to make Sphinx to properly parse the text file, as they're already in good shape, not requiring massive changes in order to be parsed. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups.

This has been fixed. - Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. - From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. - Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. - The OLPC XO-1.75 platform is now supported. - CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. - Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers.

2019-07-15unistd: protect clone3 via __ARCH_WANT_SYS_CLONE3Christian Brauner1-0/+2
This lets us catch new architectures that implicitly make use of clone3 without setting __ARCH_WANT_SYS_CLONE3. Failing on missing __ARCH_WANT_SYS_CLONE3 is a good indicator that they either did not really want this syscall or haven't really thought about whether it needs special treatment and just accidently included it in their entrypoints by e.g. generating their syscall table automatically via asm-generic/unistd.h This patch has been compile-tested for the h8300 architecture which is one of the architectures that does not yet implement clone3 and generates its syscall table via asm-generic/unistd.h.

This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps.

Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...

2019-07-13perf/core: Fix exclusive events' groupingAlexander Shishkin1-0/+5
So far, we tried to disallow grouping exclusive events for the fear of complications they would cause with moving between contexts. Specifically, moving a software group to a hardware context would violate the exclusivity rules if both groups contain matching exclusive events. This attempt was, however, unsuccessful: the check that we have in the perf_event_open() syscall is both wrong (looks at wrong PMU) and insufficient (group leader may still be exclusive), as can be illustrated by running: $ perf record -e '{intel_pt//,cycles}' uname $ perf record -e '{cycles,intel_pt//}' uname ultimately successfully. Furthermore, we are completely free to trigger the exclusivity violation by: perf -e '{cycles,intel_pt//}' -e '{intel_pt//,instructions}' even though the helpful perf record will not allow that, the ABI will. The warning later in the perf_event_open() path will also not trigger, because it's also wrong. Fix all this by validating the original group before moving, getting rid of broken safeguards and placing a useful one to perf_install_in_context().
