The existing fadvise/madvise support only supports 32-bit lengths. Add support for 64-bit lengths, enabled by the application setting sqe->off rather than sqe->len for the length. If sqe->len is set, then that is used as the 32-bit length. If sqe->len is zero, then sqe->off is read for full 64-bit support. Older kernels will return -EINVAL if 64-bit support isn't available.
