Build failed due to following missing upstream patch backports for linux-4.4.y. I don't see these patches in queue-4.4 either. I'm not aware of other dependencies of these patches:

a89f040fa34e ("x86/cpufeatures: Add X86_BUG_CPU_INSECURE")

de791821c295c ("x86/pti: Rename BUG_CPU_INSECURE to BUG_CPU_MELTDOWN")

99c6fa2511d8 ("x86/cpufeatures: Add X86_BUG_SPECTRE_V[12]")

Ah crap, I didn't catch this as I only built a x86-64 kernel here. You are right, let me go backport these as well...

Ok, should now be fixed, thanks for the report, you beat 0-day's response :)
