From 2b37c814aab74130bcf2573a9dc1551301283cea Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Fri, 25 Oct 2024 16:14:50 +0200 Subject: [PATCH] lib/Kconfig.debug: Default STRICT_DEVMEM to "y" on s390 virtio-mem currently depends on !DEVMEM | STRICT_DEVMEM. Let's default STRICT_DEVMEM to "y" just like we do for arm64 and x86. There could be ways in the future to filter access to virtio-mem device memory even without STRICT_DEVMEM, but for now let's just keep it simple.
