x86-32, NUMA: Replace srat_32.c with srat.c SRAT support implementation in srat_32.c and srat.c are generally similar; however, there are some differences. First of all, 64bit implementation supports more types of SRAT entries. 64bit supports x2apic, affinity, memory and SLIT. 32bit only supports processor and memory. Most other differences stem from different initialization protocols employed by 64bit and 32bit NUMA init paths. On 64bit, * Mappings among PXM, node and apicid are directly done in each SRAT entry callback. * Memory affinity information is passed to numa_add_memblk() which takes care of all interfacing with NUMA init. * Doesn't directly initialize NUMA configurations. All the information is recorded in numa_nodes_parsed and memblks. On 32bit, * Checks numa_off. * Things go through one more level of indirection via private tables but eventually end up initializing the same mappings. * node_start/end_pfn[] are initialized and memblock_x86_register_active_regions() is called for each memory chunk. * node_set_online() is called for each online node. * sort_node_map() is called. There are also other minor differences in sanity checking and messages but taking 64bit version should be good enough. This patch drops the 32bit specific implementation and makes the 64bit implementation common for both 32 and 64bit. The init protocol differences are dealt with in two places - the numa_add_memblk() shim added in the previous patch and new temporary numa_32.c:get_memcfg_from_srat() which wraps invocation of x86_acpi_numa_init(). The shim numa_add_memblk() handles the folowings. * node_start/end_pfn[] initialization. * node_set_online() for memory nodes. * Invocation of memblock_x86_register_active_regions(). The shim get_memcfg_from_srat() handles the followings. * numa_off check. * node_set_online() for CPU nodes. * sort_node_map() invocation. * Clearing of numa_nodes_parsed and active_ranges on failure. The shims are temporary and will be removed as the generic NUMA init path in 32bit is replaced with 64bit one.
