sysctl-driven "ps" (and friends), special-casing of kmem gid in the procfs authorization is no longer needed. Clean up this morally ambiguous code. This MFC is from fs/procfs, as procfs has been repo-copied. Unlike -CURRENT, linprocfs required modification as in -STABLE, it has direct knowledge of the inter-process debugging authorization policy. In -CURRENT, this is abstracted behind p_cansignal(). procfs.h: 1.36, 1.37 procfs_mem.c: 1.53 procfs_subr.c: 1.35 procfs_vnops.c: 1.100, 1.101 Reviewed by: jedgar, tmm
