Hi Stephen,
please provide detailed build instructions.
Building with
- commit id de5f701724ac
- defconfig arch/powerpc/configs/ppc64_defconfig
- powerpc64-linux-gnu-gcc version 11.3.0 (Ubuntu 11.3.0-1ubuntu1~22.04)
The build fails almost immediately as follow
arch/powerpc/kernel/trace/ftrace.c:839:7: error: no previous prototype for ‘arch_ftrace_match_adjust’ [-Werror=missing-prototypes]
  839 | char *arch_ftrace_match_adjust(char *str, const char *search)
      |       ^~~~~~~~~~~~~~~~~~~~~~~~
However, the same happens rolling back de5f701724ac.
Thanks
Pier
