[PATCH v3 5/6] x86/vpic: issue dpci EOI for cleared pins at ICW1

2021-01-26 Thread Roger Pau Monne
When pins are cleared from either ISR or IRR as part of the initialization sequence forward the clearing of those pins to the dpci EOI handler, as it is equivalent to an EOI. Not doing so can bring the interrupt controller state out of sync with the dpci handling logic, that expects a notification
