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@infradead.org 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?
