Re: [PATCH] cpu: Bugfix for s390 CPU driver to return a host CPU model

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Daniel,

... first ... a happy new year 2015 to all of you.


I have seen that you have suggested at Openstack review of the s390x cpu model
issue (link: https://review.openstack.org/#/c/137424/) to post a link to this
Openstack review. Completed now. :-)

It would be nice if my intermediate patch could be reviewed and pushed.
This patch is tested successfully to solve the Openstack issue and can be used
until I will provide my patch set that will implement the s390x cpu model
support at all.

Thanks in advance.

Kind regards
Daniel Hansel
