    kdb: Categorize kdb commands (similar to SysRq categorization) · 9452e977
    Daniel Thompson authored
    This patch introduces several new flags to collect kdb commands into
    groups (later allowing them to be optionally disabled).
    
    This follows similar prior art to enable/disable magic sysrq
    commands.
    
    The commands have been categorized as follows:
    
    Always on:  go (w/o args), env, set, help, ?, cpu (w/o args), sr,
                dmesg, disable_nmi, defcmd, summary, grephelp
    Mem read:   md, mdr, mdp, mds, ef, bt (with args), per_cpu
    Mem write:  mm
    Reg read:   rd
    Reg write:  go (with args), rm
    Inspect:    bt (w/o args), btp, bta, btc, btt, ps, pid, lsmod
    Flow ctrl:  bp, bl, bph, bc, be, bd, ss
    Signal:     kill
    Reboot:     reboot
    All:        cpu, kgdb, (and all of the above), nmi_console
