#     kasan: allow architectures to manage the memory-to-shadow mapping
#     
#     Currently, shadow addresses are always addr >> shift + offset.
#     However, for powerpc, the virtual address space is fragmented in
#     ways that make this simple scheme impractical.
#     
#     Allow architectures to override:
#      - kasan_shadow_to_mem
#      - kasan_mem_to_shadow
#      - addr_has_shadow
#     
#     Rename addr_has_shadow to kasan_addr_has_shadow as if it is
#     overridden it will be available in more places, increasing the
#     risk of collisions.
#     
#     If architectures do not #define their own versions, the generic
#     code will continue to run as usual.
