-//
-// For now, this module is only used on NetBSD/OpenBSD.
-// On Linux/FreeBSD, this module is test-only:
-// - On Linux, this approach requires a higher kernel version than Rust supports,
-//   and also does not work with qemu-user (as of QEMU 7.2) and Valgrind.
-//   (Looking into HWCAP_CPUID in auxvec, it appears that Valgrind is setting it
-//   to false correctly, but qemu-user is setting it to true.)
-// - On FreeBSD, this approach does not work on FreeBSD 12 on QEMU (confirmed on
-//   FreeBSD 12.{2,3,4}), and we got SIGILL (worked on FreeBSD 13 and 14).
