When skiboot starts, it first clears the CPU structs for all possible
CPUs on a system :
for (i = 0; i <= cpu_max_pir; i++)
memset(&cpu_stacks[i].cpu, 0, sizeof(struct cpu_thread));
On POWER9, cpu_max_pir is quite big, 0x7fff, and the skiboot cpu_stacks
array overlaps with the memory region in which QEMU maps the initramfs
file. Move it upwards in memory to keep it safe.
