I know that. But without IRQ_CHIP_UNMASK_ACK set this fixup won'be applied so 
setups that are not affected should work as before.

This problem was already discussed before: 
http://www.nabble.com/Level-IRQ-handling-on-Xilinx-INTC-with-ARCH%3Dpowerpc-td18711173.html

Of course, I can just modify xilinx_intc_unmask() routine to perform 
acknowledge as I did before, but it seems a hack to me.
