Restrict FUSE DAX inspection helpers to test builds and remove stale accessors that no longer participate in production paths. Keep mixed-map PFN classification and initram root attachment semantics explicit without carrying unused state in default builds. Apply the x86_64 noexecstack policy to both kernel link passes so the final ELF advertises a non-executable GNU stack and no longer relies on deprecated linker inference.

Summary
Root cause
Several test-only or obsolete helpers were compiled into the production kernel, while a mixed-map classification payload and a feature-specific mount variant retained state unused by the default build. The x86_64 link also relied on deprecated executable-stack inference when assembly inputs omitted GNU-stack notes.
Impact
The production DAX state machine, locking, token validation, reclaim flow, and teardown ordering are unchanged. The final x86_64 kernel ELF now declares a non-executable GNU stack in both link passes.
