- * KASAN_SHADOW_OFFSET:
- * This value is used to map an address to the corresponding shadow
- * address by the following formula:
- *     shadow_addr = (address >> KASAN_SHADOW_SCALE_SHIFT) + KASAN_SHADOW_OFFSET

- * (1 << (64 - KASAN_SHADOW_SCALE_SHIFT)) shadow addresses that lie in range
- * [KASAN_SHADOW_OFFSET, KASAN_SHADOW_END) cover all 64-bits of virtual
- * addresses. So KASAN_SHADOW_OFFSET should satisfy the following equation:

- *				(1ULL << (64 - KASAN_SHADOW_SCALE_SHIFT))
