* 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 installed with the SA_INTERRUPT flag, which leaves all
+ * interrupt is installed with the IRQF_DISABLED flag, which leaves all
* interrupts masked at the CPU while an FPGA interrupt handler executes.
*
* Limited testing indicates that this workaround appears to be effective
