All warnings (new ones prefixed by >>):

>> WARNING: lib/test_bitmap.o(.text.unlikely+0x5c): Section mismatch in reference from the function bitmap_copy_clear_tail() to the variable .init.rodata:clump_exp
   The function bitmap_copy_clear_tail() references
   the variable __initconst clump_exp.
   This is often because bitmap_copy_clear_tail lacks a __initconst
   annotation or the annotation of clump_exp is wrong.
