From b7fc2cc59aa5f49ecd1eae4f90ec229a7e52c47c Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 23 Aug 2017 11:17:54 -0700 Subject: MIPS: Declare various variables & functions static We currently have various variables & functions which are only used within a single translation unit, but which we don't declare static. This causes various sparse warnings of the form: arch/mips/kernel/mips-r2-to-r6-emul.c:49:1: warning: symbol 'mipsr2emustats' was not declared. Should it be static? arch/mips/kernel/unaligned.c:1381:11: warning: symbol 'reg16to32st' was not declared. Should it be static? arch/mips/mm/mmap.c:146:15: warning: symbol 'arch_mmap_rnd' was not declared. Should it be static? Fix these & others by declaring various affected variables & functions static, avoiding the sparse warnings & redundant symbols.
