104 * ...
105 *
106 * We use memcpy to avoid unaligned access to memory. To normal memory, this is
107 * fine, but the memory we are using might be mmap'd /dev/mem which under Linux
108 * on aarch64 doesn't allow unaligned access. leXdec and friends can't be used
109 * because those can optimize to an unaligned load (which often is fine, but not
110 * for mmap'd /dev/mem which has special memory attributes).
