From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> [ Upstream commit e2af9da4f867a1a54f1252bf3abc1a5c63951778 ] Fix IA64 discontig.c Section mismatch warnings. When CONFIG_SPARSEMEM=y and CONFIG_MEMORY_HOTPLUG=y, the functions computer_pernodesize() and scatter_node_data() should not be marked as __meminit because they are needed after init, on any memory hotplug event. Also, early_nr_cpus_node() is called by compute_pernodesize(), so early_nr_cpus_node() cannot be __meminit either. WARNING: modpost: vmlinux.o(.text.unlikely+0x1612): Section mismatch in reference from the function arch_alloc_nodedata() to the function .meminit.text:compute_pernodesize() The function arch_alloc_nodedata() references the function __meminit compute_pernodesize(). This is often because arch_alloc_nodedata lacks a __meminit annotation or the annotation of compute_pernodesize is wrong. WARNING: modpost: vmlinux.o(.text.unlikely+0x1692): Section mismatch in reference from the function arch_refresh_nodedata() to the function .meminit.text:scatter_node_data() The function arch_refresh_nodedata() references the function __meminit scatter_node_data(). This is often because arch_refresh_nodedata lacks a __meminit annotation or the annotation of scatter_node_data is wrong. WARNING: modpost: vmlinux.o(.text.unlikely+0x1502): Section mismatch in reference from the function compute_pernodesize() to the function .meminit.text:early_nr_cpus_node() The function compute_pernodesize() references the function __meminit early_nr_cpus_node(). This is often because compute_pernodesize lacks a __meminit annotation or the annotation of early_nr_cpus_node is wrong.
