+	debug_guardpage_minorder=
+			[KNL] When CONFIG_DEBUG_PAGEALLOC is set, this
+			parameter allows control of the order of pages that will
+			be intentionally kept free (and hence protected) by the
+			buddy allocator. Bigger value increase the probability
+			of catching random memory corruption, but reduce the
+			amount of memory for normal system use. The maximum
+			possible value is MAX_ORDER/2.  Setting this parameter
+			to 1 or 2 should be enough to identify most random
+			memory corruption problems caused by bugs in kernel or
+			driver code when a CPU writes to (or reads from) a
+			random memory location. Note that there exists a class
+			of memory corruptions problems caused by buggy H/W or
+			F/W or by drivers badly programing DMA (basically when
+			memory is written at bus level and the CPU MMU is
+			bypassed) which are not detectable by
+			CONFIG_DEBUG_PAGEALLOC, hence this option will not help
+			tracking down these problems.
