The current CP firmware can handle Usermode Queues only on MEC1.
To reflect this firmware change, this commit reduces number of compute pipelines
to 4 - 1, from 8 - 1 (the first pipeline is allocated for kgd).

Does this need to be backported to 3.19? (Does the current CP microcode
work with 3.19?)

So I added the Cc stable to the patch in my repo.
Thanks for the reminder.
