[PATCH] client-architecture termination

[Jake Moilanen]

Firmware is crashing during CAS parsing.  It appears that a portion of
Will's patch got dropped.

Indeed it got dropped, because it would make the contents of our
ibm_architecture_vec incorrect according to PAPR.  The platform
architects confirmed some time ago that what we have is correct, and
the bug is in firmware - and this was communicated to the firmware
developers.

This came up a while ago; I'm surprised that firmware hasn't fixed
their bug yet.  What firmware level are you seeing this problem with?
