2019-07-09Merge tag 'docs-5.3' of git://git.lwn.net/linuxLinus Torvalds2-4/+4
Pull Documentation updates from Jonathan Corbet: "It's been a relatively busy cycle for docs: - A fair pile of RST conversions, many from Mauro. These create more than the usual number of simple but annoying merge conflicts with other trees, unfortunately. He has a lot more of these waiting on the wings that, I think, will go to you directly later on. - A new document on how to use merges and rebases in kernel repos, and one on Spectre vulnerabilities. - Various improvements to the build system, including automatic markup of function() references because some people, for reasons I will never understand, were of the opinion that :c:func:``function()`` is unattractive and not fun to type. - We now recommend using sphinx 1.7, but still support back to 1.4. - Lots of smaller improvements, warning fixes, typo fixes, etc" * tag 'docs-5.3' of git://git.lwn.net/linux: (129 commits) docs: automarkup.py: ignore exceptions when seeking for xrefs docs: Move binderfs to admin-guide Disable Sphinx SmartyPants in HTML output doc: RCU callback locks need only _bh, not necessarily _irq docs: format kernel-parameters -- as code Doc : doc-guide : Fix a typo platform: x86: get rid of a non-existent document Add the RCU docs to the core-api manual Documentation: RCU: Add TOC tree hooks Documentation: RCU: Rename txt files to rst Documentation: RCU: Convert RCU UP systems to reST Documentation: RCU: Convert RCU linked list to reST Documentation: RCU: Convert RCU basic concepts to reST docs: filesystems: Remove uneeded .rst extension on toctables scripts/sphinx-pre-install: fix out-of-tree build docs: zh_CN: submitting-drivers.rst: Remove a duplicated Documentation/ Documentation: PGP: update for newer HW devices Documentation: Add section about CPU vulnerabilities for Spectre Documentation: platform: Delete x86-laptop-drivers.txt docs: Note that :c:func: should no longer be used ...

2019-06-14docs: watchdog: convert docs to ReST and rename to *.rstMauro Carvalho Chehab2-4/+4
Convert those documents and prepare them to be part of the kernel API book, as most of the stuff there are related to the Kernel interfaces. Still, in the future, it would make sense to split the docs, as some of the stuff is clearly focused on sysadmin tasks. 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. 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.

2019-05-08watchdog: Enforce that at least one pretimeout governor is enabledGuenter Roeck1-0/+6
Since commit "watchdog: Use depends instead of select for pretimeout governors", it was possible to enable pretimeout governors but keep all of them disabled. Doing this results in the following build failure. ../drivers/watchdog/watchdog_pretimeout.c: In function ‘watchdog_register_governor’: ../drivers/watchdog/watchdog_pretimeout.c:139:26: error: ‘WATCHDOG_PRETIMEOUT_DEFAULT_GOV’ undeclared if (!strncmp(gov->name, WATCHDOG_PRETIMEOUT_DEFAULT_GOV, Since it does not make sense to enable pretimeout support but disable all pretimeout governors, enforce that at least one of them is always enabled.

Pull stream_open conversion from Kirill Smelkov: - remove unnecessary double nonseekable_open from drivers/char/dtlk.c as noticed by Pavel Machek while reviewing nonseekable_open -> stream_open mass conversion. - the mass conversion patch promised in commit 10dce8af3422 ("fs: stream_open - opener for stream-like files so that read and write can run simultaneously without deadlock") and is automatically generated by running $ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci I've verified each generated change manually - that it is correct to convert - and each other nonseekable_open instance left - that it is either not correct to convert there, or that it is not converted due to current stream_open.cocci limitations. More details on this in the patch. - finally, change VFS to pass ppos=NULL into .read/.write for files that declare themselves streams. It was suggested by Rasmus Villemoes and makes sure that if ppos starts to be erroneously used in a stream file, such bug won't go unnoticed and will produce an oops instead of creating illusion of position change being taken into account. Note: this patch does not conflict with "fuse: Add FOPEN_STREAM to use stream_open()" that will be hopefully coming via FUSE tree, because fs/fuse/ uses new-style .read_iter/.write_iter, and for these accessors position is still passed as non-pointer kiocb.ki_pos . * tag 'stream_open-5.2' of https://lab.nexedi.com/kirr/linux: vfs: pass ppos=NULL to .read()/.write() of FMODE_STREAM files *: convert stream-like files from nonseekable_open -> stream_open dtlk: remove double call to nonseekable_open
2019-05-06*: convert stream-like files from nonseekable_open -> stream_openKirill Smelkov59-65/+65
Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af3422 ("fs: stream_open - opener for stream-like files so that read and write can run simultaneously without deadlock"), search and convert to stream_open all in-kernel nonseekable_open users for which read and write actually do not depend on ppos and where there is no other methods in file_operations which assume @offset access. I've verified each generated change manually - that it is correct to convert - and each other nonseekable_open instance left - that it is either not correct to convert there, or that it is not converted due to current stream_open.cocci limitations. The script also does not convert files that should be valid to convert, but that currently have .llseek = noop_llseek or generic_file_llseek for unknown reason despite file being opened with nonseekable_open (e.g. drivers/input/mousedev.c) Among cases converted 14 were potentially vulnerable to read vs write deadlock (see details in 10dce8af3422): drivers/char/pcmcia/cm4000_cs.c:1685:7-23: ERROR: cm4000_fops: .read() can deadlock .write();

2019-05-05watchdog: stm32: add dynamic prescaler supportLudovic Barre1-37/+47
This patch allows to define the max prescaler by compatible. To set a large range of timeout, the prescaler should be set dynamically (from the timeout request) to improve the resolution in order to have a timeout close to the expected value.

2019-05-05watchdog: Improve Kconfig entry ordering and dependenciesGuenter Roeck1-10/+10
HPWDT_NMI_DECODING depends on HP_WATCHDOG and should be next to it. This helps menuconfig identify HPWDT_NMI_DECODING as depending on HP_WATCHDOG. BCM_KONA_WDT_DEBUG depends on BCM_KONA_WDT which depends on COMPILE_TEST. Enabling BCM_KONA_WDT_DEBUG without BCM_KONA_WDT does not make sense, so drop the COMPILE_TEST dependency from it. This also improves menuconfig, which now properly associates BCM_KONA_WDT_DEBUG with BCM_KONA_WDT.

2019-05-05watchdog: npcm: Enable modular buildsGuenter Roeck1-1/+1
Most of the NPCM7XX drivers can be built as modules. The NPCM7XX watchdog driver code supports building it as module, but its configuration option is set to bool. Make itr tristate to actually support modular builds. This improves consistency with other drivers for the same platform and enables including the driver in multi- platform configurations.

2019-05-05watchdog: Make watchdog core configurable as moduleGuenter Roeck1-1/+3
Under some circumstances it may be desirable to configure the watchdog core as module. Enable it. As part of this change, mark pretimeout governors as depending on the watchdog core. This is necessary to prevent governors from being built into the kernel if the watchdog core is built as module.

2019-05-05watchdog: Move pretimeout governor configuration upGuenter Roeck1-52/+52
Watchdog pretimeout configuration was at the end of the Kconfig file, after individual watchdog drivers, and thus easy to miss. Move it right after basic watchdog option declarations. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@linux-watchdog.org>
2019-05-05watchdog: Use depends instead of select for pretimeout governorsGuenter Roeck1-14/+16
Watchdog pretimeout governors were enabled from the default governor selection using "select". As a result, the default governor was always built into the kernel, even if no watchdog driver was loaded. By using "depends on" instead of "select", we are in better control, and the governors can all be built as modules. At the same time, set the default configuration option for pretimeout governors to match WATCHDOG_CORE (meaning all pretimeout governors are by default enabled if pretimeout support is enabled). The practical impact of this change is minimal. Previously, selecting a default governor automatically enabled that governor. Now, a default governor can only be selected if that governor has been enabled. Consequently, the order of governor selection is now reversed: The governor selection is now first, followed by default governor selection.

The Kconfig currently controlling compilation of this code is: config INTEL_SCU_WATCHDOG bool "Intel SCU Watchdog for Mobile Platforms" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We leave the moduleparam.h include since the file does declare some module parameters, and leaving them as such is currently the easiest way to remain compatible with existing boot arg use cases.

2019-05-05watchdog: coh901327: make it explicitly non-modularPaul Gortmaker1-20/+4
The Kconfig currently controlling compilation of this code is: config COH901327_WATCHDOG bool "ST-Ericsson COH 901 327 watchdog" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_ALIAS is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We replace module.h with moduleparam.h since the file does actually declare some module parameters (i.e. boot args for non-modules).
