[PATCH v3 36/42] hpsa: add interrupt number to /proc/interrupts interrupt name

Don Brace

From: Robert Elliott <elliott@hp.com>

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.
