From a8331594036f22dcf037f1a75358bd0985c84cd9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 26 Feb 2025 22:37:10 +0100 Subject: [PATCH] x86/mm: Drop CONFIG_SWIOTLB for PAE Since kernels with and without CONFIG_X86_PAE are now limited to the low 4GB of physical address space, there is no need to use swiotlb any more, so stop selecting this.
