| Subject | [patch 10/18] iommu/vt-d: Adjust system_state checks |
| Message-ID | <tH6KB-5j9-9@gated-at.bofh.it> |
To enable smp_processor_id() and might_sleep() debug checks earlier, it's
required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING.
Adjust the system_state checks in dmar_parse_one_atsr() and
dmar_iommu_notify_scope_dev() to handle the extra states.
