+ Specifiers which kdb commands are enabled by default. This may
+ be set to 1 or 0 to enable all commands or disable almost all
+ commands.
+
+ Alternatively the following bitmask applies:
+
+ 0x0002 - allow arbitrary reads from memory and symbol lookup
+ 0x0004 - allow arbitrary writes to memory
+ 0x0008 - allow current register state to be inspected
+ 0x0010 - allow current register state to be modified
+ 0x0020 - allow passive inspection (backtrace, process list, lsmod)
+ 0x0040 - allow flow control management (breakpoint, single step)
+ 0x0080 - enable signalling of processes
+ 0x0100 - allow machine to be rebooted
+
+ The config option merely sets the default at boot time. Both
+ issuing 'echo X > /sys/module/kdb/parameters/cmd_enable' or
+ setting with kdb.cmd_enable=X kernel command line option will
+ override the default settings.
