Hi i have a question about device tree block area
In the function setup_mm xen copy original device tree block to the end of
xen heap space
Original device tree block area seems useless during domain0 creation but
xen discard it with kernel modules after dom0 memory allocation finished
Is there any special reason??
+) what is the job of kernel module?

There is no specific reason. It is just easier to discard all the
modules in the same place. Note that we do the same for the XSM module too.

I am not sure to understand the question here.
