During live update we will load the /tool/xenstored path from the previous

and then try to mkdir /tool again which will fail with EEXIST.

When the system is coming up after having been suspended,
restore_vcpu_affinity() is called for each domain in order to adjust
the vcpu's affinity settings in case a cpu didn't come to live again.

Use the same "xen-grant-dma" device concept for the PCI devices
behind device-tree based PCI Host controller, but with one modification.
Unlike for platform devices, we cannot use generic IOMMU bindings
(iommus property), as we need to support more flexible configuratio

Hi Carlo,
This patch seems to be missing the tools maintainers/reviewers. I have
added them now.
I am not sure what you are to generate the CCs. If you are not aware, we
have a script that will add the correct maintainers/reviewers for each
patch. The script is called "scripts/add_maintainer
