From 03e92a5e097d679acbd1fb4d2ae238a38158aa0b Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 14 Dec 2020 19:09:32 -0800 Subject: ia64: remove custom __early_pfn_to_nid() The ia64 implementation of __early_pfn_to_nid() essentially relies on the same data as the generic implementation. The correspondence between memory ranges and nodes is set in memblock during early memory initialization in register_active_ranges() function. The initialization of sparsemem that requires early_pfn_to_nid() happens later and it can use the memblock information like the other architectures.
