Just allocate the tables in kvm_arch_vm_post_create(). I've been meaning to convert x86 and ARM, but keep getting distracted/waylaid by other things.

And rename it to (*exception_handler_fn).

Hmm, yeah, I think it makes sense to let vm_install_exception_handler() be used from common code. the vector to be installed is inherently arch specific, but it would be easy enough for a test to use #ifdeffery to define the correct vector.
