Right, I'm aware. I staged the tree that made some HP servers finally
work with the latest linux-block 4.16 changes. Without thinking about
the broader implications. Anyway, I'll drop the revert from
linux-dm.git's 'for-next'.
Because I'm confident others will hunt down the irq issues.
I think Ming was looking to grab the queue mapping info and CPU related
info from the affected server.

Semi-reasonable. Lacks detail. The issue is that over the weekend
Laurence found linux-block.git commit 84676c1f21e8ff54befe98 prevents
some HP servers from booting. They'd hang when trying to initialize
their HPSA controller's devices, e.g.:
