+Subject: [PATCH] kvm: Fix stack access mode in KVM test ELF headers
+
+When the linker converts guest payload binary into a linkable resource
+object file, it somehow defaults to requesting executable stack section
+for the final test binary. This trips some build-time security checks
+on newer systems. Add explicit linker option to make the stack
+non-executable.
