From: Dan Williams <[email protected]> Replace IS_ENABLED(CONFIG_CXL_REGION) with IS_ENABLED(CONFIG_DEV_DAX_CXL) so that dax_hmem only defers Soft Reserved ranges when CXL DAX support is enabled. This makes the coordination between dax_hmem and the CXL stack more precise and prevents deferral in unrelated CXL configurations.
