    sys/alpha/mcbus      mcpcia.c 
  Log:
  Doug found that doing a W1C on MCPCIA_INT_REQ just around the time you
  clear MCPCIA_INT_MASK0 helps things substantially. So, why not indeed?
  
  Rearrange irq and cookie calculation to use shifts/masks instead
  of division. Fix things to correctly remember the intpin for that
  one in a million non-INTA PCI device.
