>> WARNING: modpost: lib/find_bit_benchmark.o(.text.unlikely+0x0): Section mismatch in reference from the (unknown reference) (unknown) to the variable .init.data:bitmap2
The function (unknown)() references
the variable __initdata bitmap2.
This is often because (unknown) lacks a __initdata
annotation or the annotation of bitmap2 is wrong.
