On a high core count, multi-socket, machine I see almost 10K lines
of output from this.  If you add other things it will become a bit
of a jumble to parse.

Perhaps the module name "archinfo" is fine, but each separate thing
it shows should get its own file.  Starting with:

    /sys/kernel/debug/x86/gdtinfo

for the current output?
