Changes from previous version:

The only changes are in patch 2.
moved early_init_dt_scan_phyp_dump from rtas.c to phyp_dump.c
Added dummy function in phyp_dump.h

Patch 3 required repatching due to changes to patch 2.
Resubmitting all patches to avoid confusion.

Thanks,
Manish

The following series of patches implement a basic framework
for hypervisor-assisted dump. The very first patch provides 
documentation explaining what this is  :-) . Yes, its supposed
to be an improvement over kdump.

A list of open issues / todo list is included in the documentation.
It also appears that the not-yet-released firmware versions this was tested 
on are still, ahem, incomplete; this work is also pending.

I have included most of the changes requested. Although, I did find
one or two, fixed in a later patch file rather than the first location
they appeared at.

This series still doesn't build on !CONFIG_RTAS configs:

This solution is to move early_init_dt_scan_phyp_dump() into
arch/powerpc/platforms/pseries/phyp_dump.c and provide a dummy
implementation in asm-powerpc/phyp_dump.c for the !CONFIG_PHYP_DUMP
case.
