Hello Frank,
Just to reinforce what Ziviani told in some comments before, the issue being discussed here, even though affecting CPU hot plug on Power, is not specifically related to Power. The issue we are seeing with CPU hot plug is just a side effect of a more serious bug in blk_mq.
The blk_mq problem that the patches pointed in this issue fix is a general blk_mq issue affecting all platforms that use this infrastructure. My understanding is that there has been lots of bug fixing in this area upstream lately.
