Hi, I'm proposing for the 2.8 cycle we officially drop supporting 64 bit guests on 32 bit hosts. For most of the KVM targets it doesn't make any sense anyway and for TCG it makes things harder (e.g. supporting 64 bit atomics on a 32 bit platform). I'm not actually convinced things actually work if built or that anyone relies on these combinations. Consider these patches a way of flushing any such users out ;-)
