scripts/tags.sh: Resolve gtags empty index generation

2023-08-11T09:33:32+00:00

commit e1b37563caffc410bb4b55f153ccb14dede66815 upstream.

gtags considers any file outside of its current working directory
"outside the source tree" and refuses to index it. For O= kernel builds,
or when "make" is invoked from a directory other then the kernel source
tree, gtags ignores the entire kernel source and generates an empty
index.

Force-set gtags current working directory to the kernel source tree.

Due to commit 9da0763bdd82 ("kbuild: Use relative path when building in
a subdir of the source tree"), if the kernel build is done in a
sub-directory of the kernel source tree, the kernel Makefile will set
the kernel's $srctree to ".." for shorter compile-time and run-time
warnings. Consequently, the list of files to be indexed will be in the
"../*" form, rendering all such paths invalid once gtags switches to the
kernel source tree as its current working directory.

If gtags indexing is requested and the build directory is not the kernel
source tree, index all files in absolute-path form.

Note, indexing in absolute-path form will not affect the generated
index, as paths in gtags indices are always relative to the gtags "root
directory" anyway (as evidenced by "gtags --dump").

tags: honor COMPILED_SOURCE with apart output directory

2017-06-05T23:42:34+00:00

When the kernel is compiled with an "O=" argument, the object files are
not in the source tree, but in the build tree.

This patch fixes O= build by looking for object files in the build tree.

scripts/tags.sh: include arch/Kconfig* for tags generation

Kconfig files under arch/ directory are ignored by all_kconfigs(),
so include them for tags generation.

scripts/tags.sh: handle OMAP platforms properly

2016-12-13T02:55:06+00:00

When SUBARCH is "omap1" or "omap2", plat-omap/ directory must be
indexed.  Handle this special case properly.

While at it, check if mach- directory exists at all.

mm: clean up non-standard page->_mapcount users

2016-07-26T23:19:19+00:00

 - Add a proper comment to page->_mapcount.

 - Introduce a macro for generating helper functions.

 - Place all special page->_mapcount values next to each other so that
   readers can see all possible values and so we don't get duplicates.
