[PATCH v1 4/5] lib/Kconfig.debug: default STRICT_DEVMEM to "y" on s390x

From: David Hildenbrand
Date: Tue Sep 10 2024 - 15:16:48 EST


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.

If this option is disabled, you allow userspace (root) access to all
of memory, including kernel and userspace memory. Accidental
