Hello,
The follow series contain a misc of fixes mostly related to the usage of

The purpose of the norevert test is to install a dummy handler that replaces
the internal Xen revert code, and then perform the revert in the post-revert

not enough, as that just reverts specific functions, but not the

When checking if an address belongs to a patch, or when resolving a symbol,
take into account all loaded livepatch payloads, even if not applied.
This is required in order for the pre-apply and post-revert hooks to work

It seems the build variables for those tests where copy-pasted from
xen_action_hooks_marker-objs and not adjusted to use the correct source files.

Currently livepatch regions are registered as virtual regions only after the

This can lead to issues when using the pre-apply or post-revert hooks, as at
