I don't know this history. And I don't care.
I thought /proc/cpuinfo should show an (almost) complete list

Fam10 processors were not designed to enter C1 on mwait.

This patch will enable default_idle for non-Intel
CPUs even if mwait is supported.
It would be better to clear MONITOR/MWAIT in the AMD specific
CPU initialize code than add workarounds everywhere else.
Why is that?
MONITOR/MWAIT is usable.
If it doesn't save power it's not
