Thread-topic: [Xen-devel] [VTD][PATCH] Fix ISA IRQ alias issue
When assign multiple devices to guest which uses PIC, ISA IRQ alias may
occur. This patch splits ISA IRQ and GSI eoi function. In ISA IRQ eoi
function, searches all assigned mirqs and does eoi for the corresponding
mirqs which match the eoi ISA IRQ. Therefore fix ISA IRQ alias issue.
