Sorry, I should have said that I found this bug on linux-next master,
which has this commit:

https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next/+/dcf0926e9b899eca754a07c4064de69815b85a38%5E%21/

. which changes CONFIG_HAVE_KVM to CONFIG_KVM. I was not aware that
this commit hadn't been merged upstream yet.

You can easily reproduce with with "defconfig" plus CONFIG_X86_FRED
(on linux-next/master).
