      x86, irq: Rename gsi_end gsi_top, and fix off by one errors · a4384df3
      Eric W. Biederman 提交于
      When I introduced the global variable gsi_end I thought gsi_end on
      io_apics was one past the end of the gsi range for the io_apic.  After
      it was pointed out the the range on io_apics was inclusive I changed
      my global variable to match.  That was a big mistake.  Inclusive
      semantics without a range start cannot describe the case when no gsi's
      are allocated.  Describing the case where no gsi's are allocated is
      important in sfi.c and mpparse.c so that we can assign gsi numbers
      instead of blindly copying the gsi assignments the BIOS has done as we
      do in the acpi case.
      
      To keep from getting the global variable confused with the gsi range
      end rename it gsi_top.
      
      To allow describing the case where no gsi's are allocated have gsi_top
      be one place the highest gsi number seen in the system.
