Miles Chen ccbd6283a9 mm/sparse: fix check_usemap_section_nr warnings ... I see a "virt_to_phys used for non-linear address" warning from check_usemap_section_nr() on arm64 platforms. In current implementation of NODE_DATA, if CONFIG_NEED_MULTIPLE_NODES=y, pglist_data is dynamically allocated and assigned to node_data[]. For example, in arch/arm64/include/asm/mmzone.h: extern struct pglist_data *node_data[]; #define NODE_DATA(nid) (node_data[(nid)]) If CONFIG_NEED_MULTIPLE_NODES=n, pglist_data is defined as a global variable named "contig_page_data". For example, in include/linux/mmzone.h: extern struct pglist_data contig_page_data; #define NODE_DATA(nid) (&contig_page_data) If CONFIG_DEBUG_VIRTUAL is not enabled, __pa() can handle both dynamically allocated linear addresses and symbol addresses. However, if (CONFIG_DEBUG_VIRTUAL=y && CONFIG_NEED_MULTIPLE_NODES=n) we can see the "virt_to_phys used for non-linear address" warning because that &contig_page_data is not a linear address on arm64. Warning message: virt_to_phys used for non-linear address: (contig_page_data+0x0/0x1c00) WARNING: CPU: 0 PID: 0 at arch/arm64/mm/physaddr.c:15 __virt_to_phys+0x58/0x68 Modules linked in: CPU: 0 PID: 0 Comm: swapper Tainted: G W 5.13.0-rc1-00074-g1140ab592e2e #3 Hardware name: linux,dummy-virt (DT) pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO BTYPE=--) Call trace: __virt_to_phys+0x58/0x68 check_usemap_section_nr+0x50/0xfc sparse_init_nid+0x1ac/0x28c sparse_init+0x1c4/0x1e0 bootmem_init+0x60/0x90 setup_arch+0x184/0x1f0 start_kernel+0x78/0x488 To fix it, create a small function to handle both translation.
