You say you remove support for ppc64 but you are removing it for both PPC64 and PPC32. Should you replace the line by: select ARCH_HAS_DEBUG_VM_PGTABLE if PPC32
select ARCH_HAS_DEVMEM_IS_ALLOWED select ARCH_HAS_ELF_RANDOMIZE select ARCH_HAS_FORTIFY_SOURCE
What about Documentation/features/debug/debug-vm-pgtable/arch-support.txt ? Christophe
