since they just duplicated the MI `reset' command. Instead of removing
them, make `reboot' an MI alias for `reboot' since this gives a better
way of killing the `r' alias for `reset'. Remove the `registers' command
that was used to kill the alias.
Turn the powerpc and sparc64 MD `halt' command into an MI command.
A copy of sparc64/db_interface.c grew in sun4v just after I found the
extra reboot commands. It has not been changed, and is now not
identical. Duplicated commands come out duplicated in ddb's online
help, but cause large problems when used (e.g., on i386's with 2 halt's
and an hwatch, typing h doesn' give the expected message about an
ambiguous command, but hangs like the halt command or a looping parseri
would).
