Hm which arches don't set it? Filtering through: arm - If !ARM_LPAE csky hexagon m68k microblaze mips - If 32-bit or !CPU_HAS_RIXI nios2 openrisc um xtensa So the usual suspects of museum pieces and museum pieces on life-support for some reason but also... usermode linux? Might that be the easiest to play with? I got this list from a basic grep for 'select ARCH_HAS_PTE_SPECIAL' so I'm not sure if um imports some other arch's kconfig or there is some other way to set it but probably this criteria is accurate... IMO: criteria for arch removal (or in case of um - adjustment :) - 32-bit (kernel), !ARCH_HAS_PTE_SPECIAL, nommu Of course, pipe dreams... > > -- > Cheers, > > David / dhildenb >
