I can find no patch which adds such a flag to __vmalloc_node_range(). I assume you're referring to "mm/vmalloc: switch to bulk allocator in __vmalloc_area_node()"? Please be quite specific when identifying patches. More specific than "the recent patches"! Also, it appears from the discussion at https://lkml.kernel.org/r/YKUWKFyLdqTYliwu@xxxxxxxxxxxxx that we'll be seeing a new version of "mm/vmalloc: switch to bulk allocator in __vmalloc_area_node()". Would it be better to build these s390 fixes into the next version of that patch series rather than as a separate followup thing?
