sparse/drivers/xen is slowly (but surely) becoming common code
and direct_remap_pfn_range is called in
drivers/xen/privcmd/privcmd.c.  Changing that usage
means changing many other (x86) files, including some that
call it with &init_mm.  (Is there a parent vma for
init_mm?)

Or did I misunderstand your point?

My point was garbled. No code outside our sparse tree directly callsdirect_remap_pfn_range() so we have free reign to define its interface.
