linux-next: build warning after merge of the akpm tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the akpm tree, today's linux-next build (powerpc
allyesconfig) produced warnings like this:

kernel/kcov.c:296:14: warning: conflicting types for built-in function '__sanitizer_cov_trace_switch'; expected 'void(long unsigned int,  void *)' [-Wbuiltin-declaration-mismatch]
  296 | void notrace __sanitizer_cov_trace_switch(u64 val, u64 *cases)
      |              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

ld: warning: orphan section `.data..Lubsan_data177' from `arch/powerpc/oprofile/op_model_pa6t.o' being placed in section `.data..Lubsan_data177'

(lots of these latter ones)

I don't know what produced these, but it is in the akpm-current or
akpm trees.
