Finished bisecting on the other machine too (Sun Fire V100 where strlen crashes): 7bd0b0f0da3b1ec11cbcc798eb0ef747a1184077 is the first bad commit commit 7bd0b0f0da3b1ec11cbcc798eb0ef747a1184077 Author: Tejun Heo Date: Thu Dec 8 10:22:09 2011 -0800 memblock: Reimplement memblock allocation using reverse free area iterator Now that all early memory information is in memblock when enabled, we can implement reverse free area iterator and use it to implement NUMA aware allocator which is then wrapped for simpler variants instead of the confusing and inefficient mending of information in separate NUMA aware allocator. Implement for_each_free_mem_range_reverse(), use it to reimplement memblock_find_in_range_node() which in turn is used by all allocators. The visible allocator interface is inconsistent and can probably use some cleanup too.
