Subject: [PATCH v2 01/11] iommu/sva: Rename CONFIG_IOMMU_SVA_LIB to CONFIG_IOMMU_SVA
Date: Fri, 17 Dec 2021 22:01:26 +0000	[thread overview]
Message-ID: <20211217220136.2762116-2-fenghua.yu@intel.com> (raw)
In-Reply-To: <20211217220136.2762116-1-fenghua.yu@intel.com>

This CONFIG option originally only referred to the Shared
Virtual Address (SVA) library. But it is now also used for
non-library portions of code.

Drop the "_LIB" suffix so that there is just one configuration
options for all code relating to SVA.

Signed-off-by: Fenghua Yu <fenghua.yu@intel.com>

v2:
- Add this patch for more meaningful name CONFIG_IOMMU_SVA
