+ xmon [PPC]
+ Format: { early | on | rw | ro | off }
+ Controls if xmon debugger is enabled. Default is off.
+ Passing only "xmon" is equivalent to "xmon=early".
+ early Call xmon as early as possible on boot; xmon
+ debugger is called from setup_arch().
+ on xmon debugger hooks will be installed so xmon
+ is only called on a kernel crash. Default mode,
+ i.e. either "ro" or "rw" mode, is controlled
+ with CONFIG_XMON_DEFAULT_RO_MODE.
+ rw xmon debugger hooks will be installed so xmon
+ is called only on a kernel crash, mode is write,
+ meaning SPR registers, memory and, other data
+ can be written using xmon commands.
+ ro same as "rw" option above but SPR registers,
+ memory, and other data can't be written using
+ xmon commands.
+ off xmon is disabled.

Currently some binary files which are generated when tests are compiled
are not ignored by git, so 'git status' catch them.
For copyloops test, fix wrong binary names already in .gitignore. For
ptrace, security, and stringloops tests add missing binary names to the
.gitignore file.
