From f3560a2ba5cbbb6c62c14dbdc1e33cb3565199d0 Mon Sep 17 00:00:00 2001 From: Kunwu Chan Date: Thu, 25 Jan 2024 16:26:37 +0800 Subject: [PATCH] powerpc/iommu: Code cleanup for cell/iommu.c This part was commented from commit 165785e5c0be ("[POWERPC] Cell iommu support") in about 17 years before. If there are no plans to enable this part code in the future, we can remove this dead code.
