The kvm structure is pretty large. A large portion of it is the vcpu
array, which is 4kB on x86_64 and arm64 as they deal with 512 vcpu
VMs. Of course, hardly anyone runs VMs this big, so this is often a
net waste of memory and cache locality.

A possible approach is to turn the fixed-size array into an xarray,
which results in a net code deletion after a bit of cleanup.

This series is on top of the current linux/master as it touches the
RISC-V implementation. Only tested on arm64.

Queued, only locally until I get a review for my replacement of patch
4 (see
https://lore.kernel.org/kvm/20211116142205.719375-1-pbonzini@redhat.com/T/ (local)).

In which case, let me send a v2 with the changes that we discussed
with Sean. It will still have my version of patch 4, but that's
nothing you can't fix.
