PAPR defines a feature negotiation protocol between host and guest
called ibm,client-architecture-support or CAS.  When invoked by the
guest this can either result in updated device tree information being
given to the guest to indicate the new configuration, or it can
trigger a reboot (called a CAS reboot) for more wide reaching
configuration changes.

CAS changes are time consuming and irritating for the user, so we'd
like to avoid them as much as possible.  We hope we can avoid them in
all situations, in fact, but there's some work to do to get there.

This series has some initial changes that get us closer to that mark.

Alexey Kardashevskiy (4):
  spapr: Fixes a leak in CAS
  spapr: Skip leading zeroes from memory@ DT node names
  spapr: Do not put empty properties for -kernel/-initrd/-append
  spapr: Stop providing RTAS blob

David Gibson (3):
  spapr: Simplify handling of pre ISA 3.0 guest workaround handling
  spapr: Move handling of special NVLink numa node from reset to init
  spapr: Perform machine reset in a more sensible order
