From 2b6509f42dc6c96ef0b625888d4aa56d2e140330 Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Fri, 27 Sep 2019 18:27:42 +0800 Subject: MIPS: Loongson64: Fix boot failure after dropping boot_mem_map From commit a94e4f24ec83 ("MIPS: init: Drop boot_mem_map") onwards, add_memory_region() is handled by memblock_add()/memblock_reserve() directly and all bootmem API should be converted to memblock API. Otherwise it will lead to boot failure, especially in the NUMA case because add_memory_region lose the node_id information.
