Somehow caused by commit 8ac0fba2da41 ("isa: Decouple X86_32 dependency from the ISA Kconfig option") I don't easily see why it causes the problem, but reverting it makes the build work. I also cannot rule out interaction with some other tree. I have reverted that commit for today. -- Cheers, Stephen Rothwell
