+	  This gives the physical address where the kernel is loaded. Normally
+	  for regular kernels this value is 0x100000 (1MB). But in the case
+	  of kexec on panic the fail safe kernel needs to run at a different
+	  address than the panic-ed kernel. This option is used to set the load
+	  address for kernels used to capture crash dump on being kexec'ed
+	  after panic. The default value for crash dump kernels is
+	  0x1000000 (16MB). This can also be set based on the "X" value as
+	  specified in the "crashkernel=YM@XM" command line boot parameter
+	  passed to the panic-ed kernel. Typically this parameter is set as
+	  crashkernel=64M@16M. Please take a look at
+	  Documentation/kdump/kdump.txt for more details about crash dumps.
