From 3194ac6e66cc7a00c1fa9fecf33a7c376b489497 Mon Sep 17 00:00:00 2001 From: David Daney Date: Fri, 8 Apr 2016 15:50:26 -0700 Subject: [PATCH] arm64: Move unflatten_device_tree() call earlier. In order to extract NUMA information from the device tree, we need to have the tree in its unflattened form. Move the call to bootmem_init() in the tail of paging_init() into setup_arch, and adjust header files so that its declaration is visible. Move the unflatten_device_tree() call between the calls to paging_init() and bootmem_init(). Follow on patches add NUMA handling to bootmem_init().
