Miller" Sender: "linux-riscv" Errors-To: linux-riscv-bounces+infradead-linux-riscv=archiver.kernel.org@lists.infradead.org From: Mike Rapoport Hi, After the discussion [1] about removal of CONFIG_NODES_SPAN_OTHER_NODES and CONFIG_HAVE_MEMBLOCK_NODE_MAP options, I took it a bit further and updated the node/zone initialization. Since all architectures have memblock, it is possible to use only the newer version of free_area_init_node() that calculates the zone and node boundaries based on memblock node mapping and architectural limits on possible zone PFNs. The architectures that still determined zone and hole sizes can be switched to the generic code and the old code that took those zone and hole sizes can be simply removed. And, since it all started from the removal of CONFIG_NODES_SPAN_OTHER_NODES, the memmap_init() is now updated to iterate over memblocks and so it does not need to perform early_pfn_to_nid() query for every PFN. v2 changes: * move deletion of one of '#ifdef CONFIG_HAVE_MEMBLOCK_NODE_MAP' from patch 2 to patch 3 where it should have been from the beginning * drop patch that introduced a free_area_init_memoryless_node() wrapper for free_area_init_node() * remove unused next_pfn(), thanks Qian * drop stale comment in memmap_init_zone(), as per David -- Sincerely yours, Mike.
