I would add that this commit removes a constraint on no-huge mode being
limited to 64M.

Looked around, I can find no issue with this change.

We still can't use  --socket-mem in no-huge mode since we can't pin memory
to socket at the moment, so the test on force_sockets can remain.

However, you missed reference to -m in the log message. Can you remove it ?


In which situation did you encounter this limitation and how did you test
this change ?
This should go in the commit log.


Thanks.
