Pull documentation fixes from Jonathan Corbet: "The Sphinx 2.0 release contained a few incompatible API changes that broke our extensions and, thus, the documentation build in general. Who knew that those deprecation warnings it was outputting actually meant we should change something? This set of fixes makes the build work again with Sphinx 2.0 and eliminates the warnings for 1.8. As part of that, we also need a few fixes to the docs for places where the new Sphinx is more strict. It is a bit late in the cycle for this kind of change, but it does fix problems that people are experiencing now. There has been some talk of raising the minimum version of Sphinx we support. I don't want to do that abruptly, though, so these changes add some glue to continue to support versions back to 1.3. We will be adding some infrastructure soon to nudge users of old versions forward, with the idea of maybe increasing our minimum version (and removing this glue) sometime in the future" * tag 'docs-5.2-fixes2' of git://git.lwn.net/linux: drm/i915: Maintain consistent documentation subsection ordering scripts/sphinx-pre-install: make it handle Sphinx versions docs: Fix conf.py for Sphinx 2.0 docs: fix multiple doc build warnings in enumeration.rst lib/list_sort: fix kerneldoc build error docs: fix numaperf.rst and add it to the doc tree doc: Cope with the deprecation of AutoReporter doc: Cope with Sphinx logging deprecations

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull SPDX update from Greg KH: "Here is a series of patches that add SPDX tags to different kernel files, based on two different things: - SPDX entries are added to a bunch of files that we missed a year ago that do not have any license information at all. These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up.

Stephen reported a false positive for ppc64_defconfig: warning: same basename if the following are built as modules: arch/powerpc/platforms/powermac/nvram.ko drivers/char/nvram.ko The former is never built as a module as you see in arch/powerpc/platforms/powermac/Makefile: # CONFIG_NVRAM is an arch. independent tristate symbol, for pmac32 we really # need this to be a bool. Cheat here and pretend CONFIG_NVRAM=m is really # CONFIG_NVRAM=y obj-$(CONFIG_NVRAM:m=y) += nvram.o Another example of false positive is arm64 defconfig: warning: same basename if the following are built as modules: arch/arm64/lib/crc32.ko lib/crc32.ko It is true CONFIG_CRC32 is a tristate option but it is always 'y' since it is select'ed by ARM64. Hence, neither of them is built as a module for the arm64 build. From the above, modules.builtin essentially contains false positives. I do not think it is a big deal as far as kmod is concerned, but false positive warnings in the kernel build make people upset. It is better to not check it. Even without builtin.modules checked, we have enough (and more solid) test coverage with allmodconfig. While I touched this part, I replaced the sed code with neater one provided by Stephen.

2019-05-18kbuild: check uniqueness of module namesMasahiro Yamada1-0/+16
In the recent build test of linux-next, Stephen saw a build error caused by a broken .tmp_versions/*.mod file: https://lkml.org/lkml/2019/5/13/991 drivers/net/phy/asix.ko and drivers/net/usb/asix.ko have the same basename, and there is a race in generating .tmp_versions/asix.mod Kbuild has not checked this before, and it suddenly shows up with obscure error messages when this kind of race occurs. Non-unique module names cause various sort of problems, but it is not trivial to catch them by eyes. Hence, this script. It checks not only real modules, but also built-in modules (i.e. controlled by tristate CONFIG option, but currently compiled with =y). Non-unique names for built-in modules also cause problems because /sys/modules/ would fall over. For the latest kernel, I tested "make allmodconfig all" (or more quickly "make allyesconfig modules"), and it detected the following: warning: same basename if the following are built as modules: drivers/regulator/88pm800.ko drivers/mfd/88pm800.ko warning: same basename if the following are built as modules: drivers/gpu/drm/bridge/adv7511/adv7511.ko drivers/media/i2c/adv7511.ko warning: same basename if the following are built as modules: drivers/net/phy/asix.ko drivers/net/usb/asix.ko warning: same basename if the following are built as modules: fs/coda/coda.ko drivers/media/platform/coda/coda.ko warning: same basename if the following are built as modules: drivers/net/phy/realtek.ko drivers/net/dsa/realtek.ko Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org> Reviewed-by: Stephen Rothwell <sfr@canb.auug.org.au> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com>

2019-05-18kbuild: remove 'addtree' and 'flags' magic for header search pathsMasahiro Yamada3-33/+13
The 'addtree' and 'flags' in scripts/Kbuild.include are so compilecated and ugly. As I mentioned in [1], Kbuild should stop automatic prefixing of header search path options. I fixed up (almost) all Makefiles in the kernel. Now 'addtree' and 'flags' have been removed. Kbuild still caters to add $(srctree)/$(src) and $(objtree)/$(obj) to the header search path for O= building, but never touches extra compiler options from ccflags-y etc. [1]: https://patchwork.kernel.org/patch/9632347/ Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-05-14scripts/gdb: add kernel config dumping commandStephen Boyd2-0/+45
lx-configdump <file> dumps the contents of the gzipped .config to a text file when the config is included in the kernel with CONFIG_IKCONFIG. By default, the file written is called config.txt, but it can be any user supplied filename as well. If the kernel config is in a module (configs.ko), then it can be loaded along with symbols for the module loaded with 'lx-symbols' and then this command will still work. Obviously if you have the whole vmlinux then this can also be achieved with scripts/extract-ikconfig, but this gdb script can be useful to confirm that the memory contents of the config in memory and the vmlinux contents on disk match what is expected.

2019-05-14scripts/gdb: find vmlinux where it was beforeStephen Boyd1-1/+5
Patch series "gdb script for kconfig and timer list". This is a handful of changes to the kernel's gdb scripts to do some more debugging with kgdb. The first patch allows the vmlinux to be reloaded from where it was specified on the command line so that this set of scripts can be used from anywhere. The second patch adds a script to dump the config.gz to a file on the host debugging machine. The third patch adds some rb tree utilities and the last patch uses those rb tree walking utilities to dump out the contents of /proc/timer_list from a system under debug. This patch (of 5): If I run 'gdb <path/to/vmlinux>' and there's the vmlinux-gdb.py file there I can properly see symbols and use the lx commands provided by the GDB scripts. But once I run 'lx-symbols' at the command prompt, gdb reloads the vmlinux symbols assuming that this script was run from the directory that has vmlinux at the root. That isn't always true, but we could just look and see what symbols were already loaded and use that instead. Let's do that so this can work by being invoked anywhere.
