Affinity on non MSI-X interrupts

[valmiki]

Hi,

Does multi MSI interrupts will also be set and routed by affinity ?

In drivers/pci/host/pcie-iproc-msi.c interrupt handler there is do while 
loop.
head = iproc_msi_read_reg(msi, IPROC_MSI_EQ_HEAD,
				  eq) & IPROC_MSI_EQ_MASK;
	do {
		tail = iproc_msi_read_reg(msi, IPROC_MSI_EQ_TAIL,
					  eq) & IPROC_MSI_EQ_MASK;

		.....
		}

		
		 */
	} while (true);

What happens if two multi MSI cards are connected and continuously 
running traffic ? Will this handler ever come out? wont this stall CPU ?
Will the interrupts be routed to different CPU's in this case also?

Regards,
Valmiki
