No

Yes, the previous one worked.

$ LANG=C make ARCH=powerpc CROSS_COMPILE=powerpc-linux- vmlinux
  CALL    scripts/checksyscalls.sh
  CALL    scripts/atomic/check-atomics.sh
  CHK     include/generated/compile.h
  CC      kernel/module.o
kernel/module.c: In function 'do_init_module':
kernel/module.c:3593:2: error: implicit declaration of function
'module_enable_ro'; did you mean 'module_enable_x'? [-Werror=implicit-
function-declaration]
 3593 |  module_enable_ro(mod, true);
      |  ^~~~~~~~~~~~~~~~
      |  module_enable_x
cc1: some warnings being treated as errors
make[1]: *** [scripts/Makefile.build:267: kernel/module.o] Error 1
make: *** [Makefile:1735: kernel] Error 2

So, should I 'git bisect skip'?

Thank you,
Giuseppe
