Ah, that one needs to be changed to check running_vcpu instead. Or this
needs to go first:
I think I prefer making the vCPU a required argument. If anyone's going to
pull a vCPU pointer out of their posterior, let the caller do it.
I understand that feeling, but still using the running vCPU is by far
the common case, and it's not worth adding a new function parameter to
all call sites.
What about using a separate function, possibly __-prefixed, for the case
where you have a very specific vCPU?
