  Modified files:
    sys/miscfs/procfs    procfs.h procfs_mem.c procfs_regs.c 
                         procfs_vnops.c 
  Log:
  Fix procfs security hole -- check permissions on meaningful I/Os (namely,
  reading/writing of mem and regs).  Also have to check for the requesting
  process being group KMEM -- this is a bit of a hack, but ps et al need it.
