  commit 892b9dcebdb7f646657e11cfdd95a385107bbefa
  Author: Jan Beulich <jbeulich@xxxxxxxx>
  Date:   Tue Jan 14 12:03:47 2020 +0100
  
      IRQ: u16 is too narrow for an event channel number
      
      FIFO event channels allow ports up to 2^17, so we need to use a wider
      field in struct pirq. Move "masked" such that it may share the 8-byte
      slot with struct arch_pirq on 64-bit arches, rather than leaving a
      7-byte hole in all cases.
      
      Take the opportunity and also add a comment regarding "arch" placement
      within the structure.
