The current defconfig for Linkstation/Kuroboxes has the "Disable Heap
Randomization" option enabled.
Since some of these machines are facing the internet, it helps to have
heap randomization enabled. This patch enables it.

Since Linkstations and Kuroboxes often have *very* little memory (as
they are embedded systems), it is desirable to get their kernels
compiled optimized for size.

Support for relocatable kdump kernel
This patch adds relocatable kernel support for kdump. With this one can
use the same regular kernel to capture the kdump. A signature (0xfeed1234)
is passed in r8 from panic code to the next kernel through kexec_sequence
and purgatory code. The signature is use

I've stumbled over these while I tried to figure out how the boot procedure
is working on powerpc. Right now (in powerpc) the comment seems to reflect
the code but not what is actually happening: regs r4-r7 aren't used and r3
is the device tree.

This looks like a relict from arch/ppc. machine_init() is accepting
only two parameters (dtb, phys) and is using only the first one.
