2018-02-20Merge branch 'kerneldoc2' into docs-nextJonathan Corbet1-301/+365
So once upon a time I set out to fix the problem reported by Tobin wherein a literal block within a kerneldoc comment would be corrupted in processing. On the way, though, I got annoyed at the way I have to learn how kernel-doc works from the beginning every time I tear into it. As a result, seven of the following eight patches just get rid of some dead code and reorganize the rest - mostly turning the 500-line process_file() function into something a bit more rational. Sphinx output is unchanged after these are applied. Then, at the end, there's a tweak to stop messing with literal blocks. If anybody was unaware that I've not done any serious Perl since the 1990's, they will certainly understand that fact now.
2018-02-20docs: Add an SPDX header to kernel-docJonathan Corbet1-0/+1

2018-02-15docs: kernel-doc: Don't mangle literal code blocks in commentsJonathan Corbet1-5/+64
It can be useful to put code snippets into kerneldoc comments; that can be done with the "::" operator at the end of a line like this:: if (desperate) run_in_circles(); The ".. code-block::" directive can also be used to this end. kernel-doc currently fails to understand these literal blocks and applies its normal markup to them, which is then treated as literal by sphinx. The result is unsightly markup instead of a useful code snippet. Apply a hack to the output code to recognize literal blocks and avoid performing any special markup on them. It's ugly, but that means it fits in well with the rest of the script. Reviewed-by: Jani Nikula <[email protected]> Signed-off-by: Jonathan Corbet <[email protected]>

STATE_FIELD describes a parser state that can handle any part of a kerneldoc comment body; rename it to STATE_BODY to reflect that. The $in_purpose variable was a hidden substate of STATE_FIELD; get rid of it and make a proper state (STATE_BODY_MAYBE) instead. This will make the subsequent process_file() splitup easier.

2018-02-13Restructure kernel-doc.rstMatthew Wilcox1-259/+217
I found the layout confusing with multiple introductions to what kernel-doc is and how to use it. I made the following changes: - Moved the 'Including kernel-doc comments' section to the end of the document -- we should explain what it *is* before we explain how to integrate it. - Moved the 'Recommendations' subsection to the top. We want people to know what to document before telling them how to do it. - Rewrite the 'Writing kernel-doc comments' section, integrating the 'Recommendations' subsection and a paragraph from 'How to format kernel-doc comments'. - Remove the paragraph about the kernel-doc script; we're supposed to be teaching people how to use punctuation to write pretty documentation, not documenting the build tooling. - Split the 'Parameters and member arguments' section into 'Function parameters' and 'Members'. Structure members are not commonly referred to as arguments. - Integrate the 'private:' and 'public:' tag descriptions into the 'Members' section. - Move the 'In-line member documentation comments' subsection up to be with the 'Members' section.

2018-02-11vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds297-913/+913
This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

59f47eff03a0 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper") replaced of_irq_parse_pci() + irq_create_of_mapping() with of_irq_parse_and_map_pci(), but neglected to capture the virq returned by irq_create_of_mapping(), so virq remained zero, which caused INTx configuration to fail. Save the virq value returned by of_irq_parse_and_map_pci() and correct the virq declaration to match the of_irq_parse_and_map_pci() signature.
