Comment 8 for bug 1297224

Recently on xen 4.5 staging git were added some tool's flags patches, I do not have time to check the ubuntu patches but in the TODO for 4.5 maybe you should also mark to check about them that perhaps other ubuntu patches can be removed.
Same thing also about a patch serie for tools prefix:
http://lists.xen.org/archives/html/xen-devel/2014-04/msg03240.html
Almost certainly be accepted and perhaps that allow you to remove some other ubuntu patches.
Also might be useful to point out some fixes or improvements required on upstream in the xen-devel instead of having to do and maintain dozens of patches in all the distros on things that can be corrected or improved without problems upstream.

I hope this information is helpful and sorry for my bad english.
