Mel Gorman 1b000a5dbe x86: make NUMA work on 32-bit ... The DISCONTIG memory model on x86 32 bit uses a remap allocator early in boot. The objective is that portions of every node are mapped in to the kernel virtual area (KVA) in place of ZONE_NORMAL so that node-local allocations can be made for pgdat and mem_map structures. With SPARSEMEM, the amount that is set aside is insufficient for all the mem_maps to be allocated. During the boot process, it falls back to using the bootmem allocator. This breaks assumptions that SPARSEMEM makes about the layout of the mem_map in memory and results in a VM_BUG_ON triggering due to pfn_to_page() returning garbage values. This patch only enables the remap allocator for use with DISCONTIG. Without SRAT support, a compile-error occurs because ACPI table parsing functions are only available in x86-64. This patch also adds no-op stubs and prints a warning message. What likely needs to be done is sharing the table parsing functions between 32 and 64 bit if they are compatible.
