This could cause a reader of /proc/*/regs to spin, because read(2) would never return end-of-file. In practice, this has much less impact than I would expect. Tools such as truss(1) make only a single, fixed-size read (into a `struct reg'). (Similarly for write(2).) The cause was a sort of typo: `uiomove_frombuf' was spelled `uiomove'.
