Cover letter [PATCH 0/2] Fix remaining RMRR issues

Hi,

here is a patch-set to fix a remaining RMRR issue in the VT-d driver. The problem was that RMRR mappings are only created for boot-time (or hotplug-time) allocated domains.

Domains allocated on demand don't get RMRR mappings, which is bad for the kdump case, for example. With this patch-set the on-demand domains also get RMRR mappings.

Regards,

Joerg
