It's very explicit by the code that it was designed to receive some small number of entries to return E2BIG along with the corrected number.
LOL, saying KVM_GET_CPUID2 was "designed" is definitely giving the KVM forefathers the benefit of the doubt.
I was going to make a different joke, i.e. that KVM_GET_CPUID2 was indeed designed the way Valeriy described, but that design was forgotten soon after.
Really, this ioctl has been such a trainwreck that I think the only good solution here is to drop it.

should we discuss KVM_GET_CPUID3 which will work "normally"?
Is anybody using KVM_GET_CPUID2 at all?
