Subject: [GIT PULL] Kbuild updates for v6.1-rc1
Date: Thu, 6 Oct 2022 23:29:44 +0900 [thread overview]
Message-ID: <CAK7LNASzGEiQfPTaLmhG4k7VAwB5yznd-VqWdJHEF2YjgSQTcA@mail.gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 9860 bytes --]
Hello Linus,
Please pull Kbuild updates for v6.1-rc1.
I attached my resolutions of the merge conflicts.
(attachment: merge-resolution.diff)
You can find a similar resolution in next-20221005.
A slight difference is that, I inserted
obj-$(CONFIG_RUST) += rust/
right after
obj-$(CONFIG_IO_URING) += io_uring/
This is the right order to keep the current link order.
Thank you.

docs: bump minimal GNU Make version to 3.82 (2022-10-06 09:16:21 +0900)
----------------------------------------------------------------
Kbuild updates for v6.1
- Remove potentially incomplete targets when Kbuid is interrupted by
SIGINT etc. in case GNU Make may miss to do that when stderr is piped
to another program.
- Rewrite the single target build so it works more correctly.
- Fix rpm-pkg builds with V=1.
- List top-level subdirectories in ./Kbuild.
- Ignore auto-generated __kstrtab_* and __kstrtabns_* symbols in kallsyms.
- Avoid two different modules in lib/zstd/ having shared code, which
potentially causes building the common code as build-in and modular
back-and-forth.
- Unify two modpost invocations to optimize the build process.
- Remove head-y syntax in favor of linker scripts for placing particular
sections in the head of vmlinux.
- Bump the minimal GNU Make version to 3.82.
- Clean up misc Makefiles and scripts.
