I will fix it in both spec_write() and in spec_read(). I glanced at some other callers, and it looks like the usual idiom is VMSPACE_IS_KERNEL_P(uio->uio_vmspace). (This actually checks whether the vmspace's vm_map's pmap is pmap_kernel(), although I'm not sure there are going to be any other vmspaces than vmspace_kernel() for which that is true.)
