Usually this is handled through include/asm-generic/.
Put the generic default implementation in include/asm-generic/hash.h.

Architectures that need to override provide their own version, e.g.
arch/m68k/include/asm/hash.h. They may #include <asm-generic/hash.h>
if they still want to reuse parts of the generic implementation.

Other architectures add "generic-y += hash.h" to their
arch/<ARCH>/include/asm/Kbuild.

<linux/hash.h> includes <asm/hash.h> t.
