When sending a call-function IPI-many to vCPUs, yield if any of
the IPI target vCPUs was preempted, we just select the first
preempted target vCPU which we found since the state of target
vCPUs can change underneath and to avoid race conditions.

On R-Car Gen3, the faulting virtual address is a 40-bit address, and
comprised of two registers. Read the upper address part, and combine
both parts, when running on a 64-bit system.

the memory allocation core already takes care of that.
