Subject: [patch V2 10/17] iommu/vt-d: Adjust system_state checks
Date: Tue, 16 May 2017 20:42:41 +0200 [thread overview]
Message-ID: <20170516184735.712365947@linutronix.de> (raw)
In-Reply-To: 20170516184231.564888231@linutronix.de
[-- Attachment #1: iommu-vt-d--Adjust-system_state-check.patch --]
[-- Type: text/plain, Size: 1260 bytes --]
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.
