Actually, it isn't a real fix, the real one is in the following two:

	ed6d043be8cd scsi: hpsa: fix selection of reply queue

Where are these commits? Neither Linus tree not -next know anything about
them....

This patchset can't guarantee that all IRQ vectors are assigned by one
online CPU, for example, in a quad-socket system, if only one processor
is present, then some of vectors are still assigned by all offline CPUs,
and it is a valid case, but still may cause io hang if drivers(hpsa,
megaraid_sas) select reply queue in current way.

So my understanding is that these irq patches are enhancements and not bug
fixes. I'll queue them for 4.17 then.
