+ Kprobes allows you to trap at almost any kernel address and

+ Enables the display of the minimum amount of free stack which each

+ This option will slow down process creation somewhat.

Include in-kernel hooks for the xmon kernel monitor/debugger.
Unless you are intending to debug the kernel, say N here.
+ Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise

+ framebuffer memory).
+ The cmdline option 'xmon' or 'xmon=early' will drop into xmon
+ very early during boot. 'xmon=on' will just enable the xmon
