Hm..  Bits in the options bitmaps are not an ABI, they come and sometimes
they go as well and manual decoding can be tedious to humans.  so I'm
wondering if something in /sys/devices/system/cpu would be more suitable.
It'd depend on just sysfs, not debugfs which is disabled in production
kernels.

Thoughts?
