'x86-32' sounds more appropriate to me - we should not perpetuate the i386 name, as we don't run on an original i386 anymore ;-) Here's what I think sounds pretty natural: CONFIG_X86_32_ABI CONFIG_X86_64_ABI CONFIG_X86_X32_ABI - CONFIG_X86_X32_ABI and CONFIG_X86_32_ABI selects CONFIG_COMPAT. - CONFIG_X86_32_ABI enables the 32-bit/32-bit system call ABI. - CONFIG_X86_X32_ABI enables the extra 64-bit/32-bit system call entries. - CONFIG_IA32_EMULATION goes away. > [...] IA32 in MSR names is part of the MSR name and should not be taken out. Yes, of course.
