+config EARLY_PRINTK
+       bool "Early printk" if EMBEDDED && DEBUG_KERNEL
+       default y
+       help
+         Write kernel log output directly via the hypervisor console.
+
+         This is useful for kernel debugging when your machine crashes very
+         early before the console code is initialized. For normal operation
+         it is not recommended because it looks ugly and doesn't cooperate
+         with klogd/syslogd. You should normally N here,
+         unless you want to debug such a crash.
+
+config DEBUG_STACKOVERFLOW
+       bool "Check for stack overflows"
+       depends on DEBUG_KERNEL
+       help
+         This option will cause messages to be printed if free stack space
+         drops below a certain limit.
+
+config DEBUG_STACK_USAGE
+       bool "Stack utilization instrumentation"
+       depends on DEBUG_KERNEL
+       help
+         Enables the display of the minimum amount of free stack which each
+         task has ever had available in the sysrq-T and sysrq-P debug output.
+
+         This option will slow down process creation somewhat.
+
+config DEBUG_EXTRA_FLAGS
+       string "Additional compiler arguments when building with '-g'"
+       depends on DEBUG_INFO
+       default ""
+       help
+         Debug info can be large, and flags like
+         `-femit-struct-debug-baseonly' can reduce the kernel file
+         size and build time noticeably.  Such flags are often
+         helpful if the main use of debug info is line number info.
