Fix build errors when built for PPC64:
These variables are only used on PPC32 so they don't need to be
initialized for PPC64.

One of the primary issues with Firmware Assisted Dump (fadump) on Power
is that it needs a large amount of memory to be reserved. This reserved
memory is used for saving the contents of old crashed kernel's memory before
fadump capture kernel uses old kernel's memory area to boot. However, This

Add an interface to allow a custom reserved memory to be marked as
ZONE_MOVABLE. This will help some subsystem's to convert their reserved
memory region into ZONE_MOVABLE so that the memory can still be available
to user applications.
The approach is based on Joonsoo Kim'

fadump fails to register when there are holes in reserved memory area.
This can happen if user has hot-removed a memory that falls in the fadump
reserved memory area. Throw a meaningful error message to the user in
such case.

For fadump to work successfully there should not be any holes in reserved
memory ranges where kernel has asked firmware to move the content of old
kernel memory in event of crash. Now that fadump reserved memory is marked
as movable zone, this memory area is now not protec
