From 8886640dade4ae2595fcdce511c8bcc716aa47d3 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini <pbonzini@redhat.com> Date: Thu, 11 Jan 2024 03:00:34 -0500 Subject: kvm: replace __KVM_HAVE_READONLY_MEM with Kconfig symbol KVM uses __KVM_HAVE_* symbols in the architecture-dependent uapi/asm/kvm.h to mask unused definitions in include/uapi/linux/kvm.h. __KVM_HAVE_READONLY_MEM however was nothing but a misguided attempt to define KVM_CAP_READONLY_MEM only on architectures where KVM_CHECK_EXTENSION(KVM_CAP_READONLY_MEM) could possibly return nonzero. This however does not make sense, and it prevented userspace from supporting this architecture-independent feature without recompilation. Therefore, these days __KVM_HAVE_READONLY_MEM does not mask anything and is only used in virt/kvm/kvm_main.c. Userspace does not need to test it and there should be no need for it to exist. Remove it and replace it with a Kconfig symbol within Linux source code.
