Hi, just pointing out a few typos...

There was a previous effort to add support for the PAPR
architected ibm,drc-info property. This property provides a more
memory compact representation of a paritions Dynamic Reconfig

s/paritions/partition's

Connectors (DRC). These can otherwise be thought of as currently
partitioned, or available but yet to be partitioned system resources
such as cpus, memory, and physical/logical IOA devices.

The initial implementation proved buggy and was fully turned of by

s/turned of/turned off

disabling the bit in the appropriate CAS support vector. We now have
PowerVM firmware in the field that supports this new property, and
further to suppport partitions with 24TB+ of possible memory this

s/suppport/support

property is required to perform platform migration.

This serious fixs the short comings of the previous submission

Either "seriously fixes the shortcomings", or "fixes the serious 
shortcomings?"

Thanks,
