powerpc/mm/hash: Check for non-kernel address in get_kernel_vsid() get_kernel_vsid() has a very stern comment saying that it's only valid for kernel addresses, but there's nothing in the code to enforce that. Rather than hoping our callers are well behaved, add a check and return a VSID of 0 (invalid). Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
