-	help
-	  This option enables tracing of dynamically allocated kernel memory
-	  to see if memory is used before it has been given an initial value.
-	  Be aware that this requires half of your memory for bookkeeping and
-	  will insert extra code at *every* read and write to tracked memory
-	  thus slow down the kernel code (but user code is unaffected).
-
-	  The kernel may be started with kmemcheck=0 or kmemcheck=1 to disable
-	  or enable kmemcheck at boot-time. If the kernel is started with
-	  kmemcheck=0, the large memory and CPU overhead is not incurred.

-	help
-	  Select the maximum number of errors to store in the queue. Since
-	  errors can occur virtually anywhere and in any context, we need a
-	  temporary storage area which is guarantueed not to generate any
-	  other faults. The queue will be emptied as soon as a tasklet may

-config KMEMCHECK_PARTIAL_OK
-	bool "kmemcheck: allow partially uninitialized memory"

-	default y
-	help
-	  This option works around certain GCC optimizations that produce
