[Mel Gorman]

Once all patches are applied, two new command-line parameters exist -
kernelcore and noeasyrclm. This patch adds the necessary documentation.

+	kernelcore=nn[KMG]	[KNL,IA-32,IA-64,PPC,X86-64] This parameter
+			specifies the amount of memory usable by the kernel.
+			The requested amount is spread evenly throughout
+			all nodes in the system. The remaining memory
+			in each node is used for EasyRclm pages. In the
+			event, a node is too small to have both kernelcore
+			and EasyRclm pages, kernelcore pages will take
+			priority and other nodes will have a larger
+			number of kernelcore pages.  The EasyRclm zone
+			is used for the allocation of pages on behalf
+			of a process and for HugeTLB pages. On ppc64,
+			it is likely that memory sections on this zone
+			can be offlined. Note that allocations like
+			PTEs-from-HighMem still use the HighMem zone if
+			it exists, and the Normal zone if it does not.
