These are already defined in the same file: /* * MMU families */ #define MMU_FTR_HPTE_TABLE ASM_CONST(0x00000001) #define MMU_FTR_TYPE_8xx ASM_CONST(0x00000002) #define MMU_FTR_TYPE_40x ASM_CONST(0x00000004) #define MMU_FTR_TYPE_44x ASM_CONST(0x00000008) #define MMU_FTR_TYPE_FSL_E ASM_CONST(0x00000010) #define MMU_FTR_TYPE_47x ASM_CONST(0x00000020) #define MMU_FTR_TYPE_RADIX ASM_CONST(0x00000040) And the values for the current CPU are in cur_cpu_spec->mmu_features. So if you must export anything, make it that value, and hopefully the rest of the patch goes away. cheers
