KVM: PPC: Book3S: Compile fix for ppc32 in HIOR access code
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.
Also, on PPC32 we can not use get_user/put_user for 64bit wide variables,
as there is no single instruction that could load or store variables that big.
So instead, we have to use copy_from/to_user which works everywhere.
