From 964d06b4ed212d85ff589a9438baeb6c4fff3272 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 15 Apr 2019 10:35:53 +0200 Subject: [PATCH] s390: drop CONFIG_VIRT_TO_BUS VIRT_TO_BUS is only used for legacy device PCI and ISA drivers using virt_to_bus() instead of the streaming DMA mapping API, and the remaining drivers generally don't work on 64-bit architectures. Two of these drivers also cause a build warning on s390, so instead of trying to fix that, let's just disable the option as we do on most architectures now.
