      powerpc: Fix i8259 cascade on pSeries with XICS interrupt controller · 8b1af56b
      Paul Mackerras authored
      It turns out that commit f9bd170a
      
      
      broke the cascade from XICS to i8259 on pSeries machines; specifically
      we ended up not ever doing the EOI on the XICS for the cascade.  The
      result was that interrupts from the serial ports (and presumably any
      other devices using ISA interrupts) didn't get through.  This fixes
      it and also simplifies the code, by doing the EOI on the XICS in the
      xics_get_irq routine after reading and acking the interrupt on the
      i8259.
