All warnings (new ones prefixed by >>):

>> WARNING: modpost: vmlinux.o(.text+0x2b8d9e): Section mismatch in reference from the function padata_do_multithreaded() to the function .init.text:padata_work_alloc_mt()
   The function padata_do_multithreaded() references
   the function __init padata_work_alloc_mt().
   This is often because padata_do_multithreaded lacks a __init
   annotation or the annotation of padata_work_alloc_mt is wrong.

   The function padata_do_multithreaded() references
   the function __init padata_works_free().
   This is often because padata_do_multithreaded lacks a __init
   annotation or the annotation of padata_works_free is wrong.
