From 620e5050827008ab207a8dfcc44cb79f07f1942c Mon Sep 17 00:00:00 2001 From: Vladimir Murzin Date: Tue, 10 Sep 2013 18:42:07 +0200 Subject: [PATCH] powerpc: Fix section mismatch warning for prom_rtas_call While cross-building for PPC64 I've got WARNING: vmlinux.o(.text.unlikely+0x1ba): Section mismatch in reference from the function .prom_rtas_call() to the variable .init.data:dt_string_start The function .prom_rtas_call() references the variable __initdata dt_string_start. This is often because .prom_rtas_call lacks a __initdata annotation or the annotation of dt_string_start is wrong. WARNING: vmlinux.o(.meminit.text+0xeb0): Section mismatch in reference from the function .free_area_init_core.isra.47() to the function .init.text:.set_pageblock_order() The function __meminit .free_area_init_core.isra.47() references a function __init .set_pageblock_order(). If .set_pageblock_order is only used by .free_area_init_core.isra.47 then annotate .set_pageblock_order with a matching annotation. Fix it by proper annotation of prom_rtas_call.
