* mips-xdep.c (REGISTER_PTRACE_ADDR, fetch_inferior_registers,
store_inferior_registers): Replace unexplained numbers
with manifest constants from a DECstation header file.
* xm-mips.h (KERNEL_U_ADDR): Get from <machine/param.h>.
(REGISTER_U_ADDR): Fix up for Ultrix 4.2.
* tm-tahoe.h, xm-tahoe.h (KERNEL_U_ADDR): Move macro to xm-tahoe.h.
* stack.c (_initialize_stack): "dow" should be a valid abbreviation
for "down". Suggested by Richard Stallman.
