Neither of these should ever be changed once set. Make them const and fix up the users that try to modify it in-place. In one case kmalloc+memcpy is replaced with kstrdup() to avoid modifying the string. Build tested with defconfigs on ARM, PowerPC, Sparc, MIPS, x86 among others.Grant, This breaks powerpc chroma_defconfig in next-20121127 with: arch/powerpc/sysdev/scom.c:160:17: error: assignment discards 'const' qualifier from pointer target type [-Werror] The following fixes it. The change is to generic code, so I'm not sure it's the right fix as it may break other configs/archs.
That is rather risky. Post it as a patch to core code, but in the mean time I'll patch the powerpc scom code. g.
