From 744baba0c4072b04664952a89292e4708eaf949a Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 2 May 2011 14:18:53 +0200 Subject: x86, NUMA: Enable build of generic NUMA init code on 32bit Generic NUMA init code was moved to numa.c from numa_64.c but is still guaraded by CONFIG_X86_64. This patch removes the compile guard and enables compiling on 32bit. * numa_add_memblk() and numa_set_distance() clash with the shim implementation in numa_32.c and are left out. * memory_add_physaddr_to_nid() clashes with 32bit implementation and is left out. * MAX_DMA_PFN definition in dma.h moved out of !CONFIG_X86_32. * node_data definition in numa_32.c removed in favor of the one in numa.c. There are places where ulong is assumed to be 64bit. The next patch will fix them up. Note that although the code is compiled it isn't used yet and this patch doesn't cause any functional change.
