kbuild: fix DT binding schema rule to detect command line changes

2020-02-26T17:23:12+00:00

This if_change_rule is not working properly; it cannot detect any command line change. The reason is because cmd-check in scripts/Kbuild.include compares $(cmd_$@) and $(cmd_$1), but cmd_dtc_dt_yaml does not exist here. For if_change_rule to work properly, the stem part of cmd_* and rule_* must match. Because this cmd_and_fixdep invokes cmd_dtc, this rule must be named rule_dtc.

scripts/get_maintainer.pl: deprioritize old Fixes: addresses

2020-02-21T19:22:15+00:00

Recently, I found that get_maintainer was causing me to send emails to the old addresses for maintainers. Since I usually just trust the output of get_maintainer to know the right email address, I didn't even look carefully and fired off two patch series that went to the wrong place. Oops. The problem was introduced recently when trying to add signatures from Fixes. The problem was that these email addresses were added too early in the process of compiling our list of places to send. Things added to the list earlier are considered more canonical and when we later added maintainer entries we ended up deduplicating to the old address. Here are two examples using mainline commits (to make it easier to replicate) for the two maintainers that I messed up recently: $ git format-patch d8549bcd0529~..d8549bcd0529 $ ./scripts/get_maintainer.pl 0001-clk-Add-clk_hw*.patch | grep Boyd Stephen Boyd ... $ git format-patch 6d1238aa3395~..6d1238aa3395 $ ./scripts/get_maintainer.pl 0001-arm64-dts-qcom-qcs404*.patch | grep Andy Andy Gross Let's move the adding of addresses from Fixes: to the end since the email addresses from these are much more likely to be older. After this patch the above examples get the right addresses for the two examples.

get_maintainer: remove uses of P: for maintainer name

2020-02-21T19:22:15+00:00

Commit 1ca84ed6425f ("MAINTAINERS: Reclaim the P: tag for Maintainer Entry Profile") changed the use of the "P:" tag from "Person" to "Profile (ie: special subsystem coding styles and characteristics)" Change how get_maintainer.pl parses the "P:" tag to match.

kbuild: fix mismatch between .version and include/generated/compile.h

2020-02-10T20:18:40+00:00

Since commit 56d589361572 ("kbuild: do not create orphan built-in.a or obj-y objects"), scripts/link-vmlinux.sh does nothing when descending into init/. Once the version number becomes out of sync between .version and include/generated/compile.h, it is not self-healing. [How to reproduce] $ echo 100 > .version $ make You will see the number in the .version is always bigger than that in compile.h by one. After this, every time you run 'make', the vmlinux is re-linked even when none of source files is updated.

Allow git builds of Sphinx

2020-02-05T17:33:44+00:00

When using a non-release version of Sphinx, from a local build (with improvements for kernel doc handling, why not), sphinx-build --version reports versions of the form sphinx-build 3.0.0+/4703d9119972 i.e. base version, a plus symbol, slash, and the start of the git hash of whatever repository the command is run in (no, not the hash that was used to build Sphinx!). This patch fixes the installation check in sphinx-pre-install to recognise such version output.

kconfig: Invalidate all symbols after changing to y or m.

2020-02-05T04:45:37+00:00

Since commit 89b9060987d9 ("kconfig: Add yes2modconfig and mod2yesconfig targets.") forgot to clear SYMBOL_VALID bit after changing to y or m, these targets did not save the changes. Call sym_clear_all_valid() so that all symbols are revalidated. Fixes: 89b9060987d9 ("kconfig: Add yes2modconfig and mod2yesconfig targets.") Signed-off-by: Tetsuo Handa Signed-off-by: Masahiro Yamada
