+       help
+         This gives the physical address where the kernel is loaded.
+
+         If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
+         bzImage will decompress itself to above physical address and
+         run from there. Otherwise, bzImage will run from the address where
+         it has been loaded by the boot loader and will ignore above physical
+         address.
+
+         In normal kdump cases one does not have to set/change this option
+         as now bzImage can be compiled as a completely relocatable image
+         (CONFIG_RELOCATABLE=y) and be used to load and run from a different
+         address. This option is mainly useful for the folks who don't want
+         to use a bzImage for capturing the crash dump and want to use a
+         vmlinux instead. vmlinux is not relocatable hence a kernel needs
+         to be specifically compiled to run from a specific memory area
+         (normally a reserved region) and this option comes handy.
+
+         So if you are using bzImage for capturing the crash dump, leave
+         the value here unchanged to 0x100000 and set CONFIG_RELOCATABLE=y.
+         Otherwise if you plan to use vmlinux for capturing the crash dump
+         change this value to start of the reserved region (Typically 16MB
+         0x1000000). In other words, it can 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.
+
+         Usage of bzImage for capturing the crash dump is recommended as
+         one does not have to build two kernels. Same kernel can be used
+         as production kernel and capture kernel. Above option should have
+         gone away after relocatable bzImage support is introduced. But it
+         is present because there are users out there who continue to use
+         vmlinux for dump capture. This option should go away down the
+         line.
+
+         Don't change this unless you know what you are doing.
