The Dynamic Logical Partitioning (DLPAR) capabilities of the powerpc pseries
platform allows for the addition and removal of resources (i.e. cpus,
memory, pci devices) from a partition. The removal of a resource involves
removing the resource's node from the device tree and then returning the
resource to firmware via the rtas set-indicator call. To add a resource, it
is first obtained from firmware via the rtas set-indicator call and then a
new device tree node is created using the ibm,configure-coinnector rtas call
and added to the device tree.
The following set of patches implements the needed infrastructure to have the
kernel handle the DLPAR addition and removal of memory and cpus (other
DLPAR'able items to follow in future patches). The framework for this is
to create a set of probe/release sysfs files in pseries that will add or
remove the cpu or memory to the system.
The majority of the code is powerpc/pseries specific except for PATCH 3/5, so
I am cc'ing lkml.
Patches include in this set:
1/5 - DLPAR infracstructure for powerpc/pseries platform.
2/5 - Move the of_drconf_cell struct to prom.h
3/5 - Export the memory sysdev class
4/5 - Memory DLPAR handling
5/5 - CPU DLPAR handling

Please pardon the re-send, I borked the lkml address on cc the first time.

Disregard. Re-sending with corrections.

It looks like a couple of your patches have some checkpatch issues..
Could you run these through scripts/checkpatch.pl and clean up any
problems it raises ? Specifically patches 1, 4, and 5 ..

thanks for checking this, I obviously forgot. I'll post updated patches
(after running checkpatch on them) with fixes.
