We have never implemented amd64_get_ioperm and amd64_set_ioperm. There
are libarch stubs, but the kernel support has never been enabled. I'm
guessing nobody will miss it when it's gone.
The man page also contains amusing lies like "The permission bitmap
contains 1024 bits in 32 longwords." It's hard to say how big the
permission bitmap is because it doesn't exist, but in any case 1024 /
64 is only 16.
