Subject: [PATCH v5 17/17] iommu/amd: Remove unused GCR3 table parameters from struct protection_domain
Date: Tue, 16 Jan 2024 16:53:35 +0000	[thread overview]
Message-ID: <20240116165335.6043-18-vasant.hegde@amd.com> (raw)

Since they are moved to struct iommu_dev_data, and the driver has been
ported to use them.
