* PM / core: Update kerneldoc comments in pm.hRafael J. Wysocki2017-02-06
| | | | | | | | | | | | | | Refresh the struct dev_pm_ops kerneldoc comment, so that it looks better and is more readable after processing by Sphinx, and drop the kerneldoc marker from a few other comments ("PM_EVENT_ messages" and a couple of enum types declarations) which are not proper kerneldoc and generally confuse Sphinx. Also change the comment describing struct dev_pm_domain into a kerneldoc one. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

* | Documentation/sphinx: make targets independent of Sphinx work for HAVE_SPHINX=0Jani Nikula2017-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Make targets that don't depend on Sphinx work without warnings about missing Sphinx. 'make cleandocs' will work without Sphinx just fine, and the targets that are no-ops for Sphinx should just be skipped. Move them outside of the HAVE_SPHINX checks to take precedence over the .DEFAULT target for HAVE_SPHINX=0.

* | Documentation/sphinx: prevent generation of .pyc files in the source treeJani Nikula2017-02-01
|/ | | | | | | | | | | | | | | | | | | | | Use PYTHONDONTWRITEBYTECODE=1 to prevent python from creating .pyc files in the source tree. Python 3.2 has a __pycache__ scheme [1], but before that the only alternative seems to be to copy the source files to the build tree to ensure the .pyc files are created there too. Just prevent .pyc file generation for simplicity. Considering the small amount of python code to compile (assuming sphinx itself has .pyc around), the impact on build is neglible.

| | | | | | | | | | | | | | | | | | | Convert deviceiobook.tmpl to RST and incorporate it into the driver API manual. Like the rest of our documentation, this one could use some work. There's no mention of ioremap() and friends, no mention of io_read*() and friends. But we have nice documentation for all those folks writing new drivers that do port I/O :). The :c:func: notation has been left off of all the read*/write* functions. There's no kerneldoc comments for them anyway, so those links will never be live, and writing a bunch of repetitive "read a byte from I/O memory" comments lacks appeal.

* kernel-doc: make highlights more homogenous for the various backendsPaolo Bonzini2017-01-04
| | | | | | | | | | | | | | | | | | | $type_struct_full and friends are only used by the restructuredText backend, because it needs to separate enum/struct/typedef/union from the name of the type. However, $type_struct is *also* used by the rST backend. This is confusing. This patch replaces $type_struct's use in the rST backend with a new $type_fallback; it modifies $type_struct so that it can be used in the rST backend; and creates regular expressions like $type_struct for enum/typedef/union, for use in all backends. Note that, compared to $type_*_full, in the new regexes $1 includes both the "kind" and the name (before, $1 was pretty much a constant).

| | | | | | | | | | | | | | | | An inline function can have an attribute, as in include/linux/log2.h, and kernel-doc handles this already for simple cases. However, some attributes have arguments (e.g. the "target" attribute). Handle those too. Furthermore, attributes could be at the beginning of a function declaration, before the return type. To correctly handle this case, you need to strip spaces after the attributes; otherwise, dump_function is left confused.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timer type simplifications caused a new gcc warning: drivers/base/power/domain.c: In function ‘genpd_runtime_suspend’: drivers/base/power/domain.c:562:14: warning: ‘time_start’ may be used uninitialized in this function [-Wmaybe-uninitialized] elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start)); despite the actual use of "time_start" not having changed in any way. It appears that simply changing the type of ktime_t from a union to a plain scalar type made gcc check the use. The variable wasn't actually used uninitialized, but gcc apparently failed to notice that the conditional around the use was exactly the same as the conditional around the initialization of that variable. Add an unnecessary initialization just to shut up the compiler. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | * | cpu/hotplug: Cleanup state namesThomas Gleixner2016-12-25

The script basically converted the state constant to a string, but the cleanup to convert these strings into meaningful ones did not happen. Replace all the useless strings with 'subsys/xxx/yyy:state' strings which are used in all the other places already.

Remove them and all related code. Remove also the now pointless cpu notifier error injection mechanism. The states can be executed step by step and error rollback is the same as cpu down, so any state transition can be tested w/o requiring the notifier error injection. Some CPU hotplug states are kept as they are (ab)used for hotplug state tracking.
