Hi all,
After merging the kbuild tree, today's linux-next build (x86_64
allmodconfig) failed like this:
cc1: fatal error: FORCE: No such file or directory
compilation terminated.
Presuably caused by commit
15bb90419621 ("arch: syscalls: add missing FORCE and fix 'targets' to make if_changed work")Sorry, this happens only when CONFIG_XEN=y, and I did not cover all cases. I will fix it for tomorrow's linux-next. If it is not too late, you can apply the following locally.
diff --git a/arch/x86/entry/syscalls/Makefile b/arch/x86/entry/syscalls/Makefile
index e1c7ddb7546b..ea6ffb51b9a3 100644

I have used the kbuild tree from next-20210219 for today. -- Cheers, Stephen Rothwell
