Thank you for your work on this. Due to personal circumstances I have
been unable to do any pdx86 patch review for the last 2 weeks.

I see that there have been lots of comments on this series already please
send a new version 2 addressing all the existing comments. Then I will
review version 2 once posted.

Regards,

Hans
