I presume this was supposed to write "Hello World\n" to a file but
sizeof(addr) is 1.
Since we already support tagged pointers in user space (as long as they
are not passed into the kernel), the above example could tag the pointer
unconditionally and only clear it before write() if
!arm64_syscall_tbi_is_present().
