[Crash-utility] [PATCH v4 0/4] vmalloc translation support for PPC

The following series implements :

 * An infrastructure for platform based vmalloc translation for PPC32
 * vmalloc translation support for PPC44x

Changes since V3:

 * Use platform specific 'page flags'
 * Avoid calling dump_mem_map() by checking if there is a page associated
   with the physical memory. (Suggested by: Dave)

Changes since V2:

 * Rebased to crash-6.0.3
 * Maintains a list of probe functions, rather than platform
   definitions.


Each platform can define their own probe_function which would get the name of the
ppc platform (read from kernel) and the probe can check if it is one of its variant.
The probe function can then update the 'platform' defintions for the virtual address
translation.

If none of the defined platforms match, we fall back to using the default PPC32
definitions.
