* cause a problem with level interrupt requests, such as Ethernet. The
* problem occurs when a level interrupt request is asserted while its
* interrupt input is masked in the FPGA, which results in a missed
* interrupt.
*
* In an attempt to workaround the problem with missed interrupts, the
* mask_ack routine for all of the FPGA interrupts has been changed from
* fpga_mask_ack_irq() to fpga_ack_irq() so that the specific FPGA interrupt
* being serviced is left unmasked. We can do this because the FPGA cascade
* interrupt is run with all interrupts masked.
*
* Limited testing indicates that this workaround appears to be effective
* for the smc9194 Ethernet driver used on the Innovator. It should work
* on other FPGA interrupts as well, but any drivers that explicitly mask
* interrupts at the interrupt controller via disable_irq/enable_irq
