This patch corrects the build issue by requiring explicit support for
IRQFD to be defined, and only defining it on x86 (the only arch fully
supported). The code itself isnt architecture dependent, but we need
to add a new file to each makefile, advertise the capability, and
of course, test that it works for each supported arch. We will submit
patches against each relevant arch at a later time to enable support
there as well.

+config HAVE_KVM_EVENTFD
+ bool
+ default y

The build system will complain if it sees a symbol used but not defined; so you have to define it for all four archs. So I went ahead and did virt/kvm/Kconfig and adapted your patch to use it.
