[v5,36/42] hpsa: add interrupt number to /proc/interrupts interrupt name

Commit Message

Don Brace April 23, 2015, 2:34 p.m. UTC

From: Robert Elliott <[e-mail]>

Add the interrupt number to the interrupt names that
appear in /proc/interrupts, so they are unique

Also, delete the IRQ and DAC prints.  Other parts of the kernel
already print the IRQ assignments, and dual-address-cycle support
has not been interesting since the parallel PCI bus went from
32 to 64 bits wide.
