From 08b5e79ebdb58868cbb6976ba0e3898029394e6d Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 13 Oct 2016 16:27:30 +1100 Subject: [PATCH] powerpc/mm: Drop dump_numa_memory_topology() At boot we dump the NUMA memory topology in dump_numa_memory_topology(), at KERN_DEBUG level, resulting in output like: Node 0 Memory: 0x0-0x100000000 Node 1 Memory: 0x100000000-0x200000000 Which is nice enough, but immediately after that we iterate over each node and call setup_node_data(), which also prints out the node ranges, at KERN_INFO, giving eg: numa: Initmem setup node 0 [mem 0x00000000-0xffffffff] numa: Initmem setup node 1 [mem 0x100000000-0x1ffffffff] Additionally dump_numa_memory_topology() does not use KERN_CONT correctly, resulting in split output lines on recent kernels. So drop dump_numa_memory_topology() as superfluous chatter.
