[ Upstream commit 7d8ed162e6a92268d4b2b84d364a931216102c8e ]
commit 6a9531c3a880 ("memblock: fix crash when reserved memory is not added to memory") introduce the usage of early_pfn_to_nid, which is not defined in memblock tests.
The original definition of early_pfn_to_nid is defined in mm.h, so let add this in the corresponding mm.h.
