Subject: [PATCH v2 07/19] iommu/vt-d: Remove dead code when CONFIG_INTEL_IOMMU is not set
Date: Wed, 5 Aug 2026 07:43:01 +0800 [thread overview]
Message-ID: <20260804234314.3087110-8-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20260804234314.3087110-1-baolu.lu@linux.intel.com>
From: Kevin Tian <kevin.tian@intel.com>
Those are leftovers and unreachable now: the entire intel directory
is built only when CONFIG_INTEL_IOMMU is set.
