We were failing to compile on book3s_32 with the following errors:

arch/powerpc/kvm/book3s_pr.c:883:45: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
arch/powerpc/kvm/book3s_pr.c:898:79: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

Fix this by explicity casting the u64 to long before we use it as a pointer.
