From 991eb43af989002d5c7f4a2ff2a6c806a912b51b Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Mon, 14 May 2007 17:11:58 -0500 Subject: [PATCH] [POWERPC] Fix COMMON symbol warnings We get the following warnings in various ARCH=powerpc builds: WARNING: "ee_restarts" [arch/powerpc/kernel/built-in] is COMMON symbol WARNING: "fee_restarts" [arch/powerpc/kernel/built-in] is COMMON symbol WARNING: "htab_hash_searches" [arch/powerpc/mm/built-in] is COMMON symbol WARNING: "next_slot" [arch/powerpc/mm/built-in] is COMMON symbol WARNING: "mmu_hash_lock" [arch/powerpc/mm/built-in] is COMMON symbol WARNING: "primary_pteg_full" [arch/powerpc/mm/built-in] is COMMON symbol WARNING: "global_dbcr0" [arch/powerpc/kernel/built-in] is COMMON symbol Switch to moving local symbols (except mmu_hash_lock which is global) and space directive instead.
