#     powerpc/64s/radix: Fix radix_kvm_prefetch_workaround paca access of not possible CPU
#     
#     If possible CPUs are limited (e.g., by kexec), then the kvm prefetch
#     workaround function can access the paca pointer for a !possible CPU.
#     
#     Fixes: d2e60075a3d44 ("powerpc/64: Use array of paca pointers and allocate pacas individually")
