Sorry for the long delay to get these two regressions fixed, it really cost me some time to read and understand Xen IRQ code. Patch 1 fixes the failure to register ACPI SCI interrupt on Xen domain0 by reworking acpi_gsi_to_irq(). I will backport it to v3.18 too once it reaches the mainstream kernel. Patch 2 fixes the regression in Xen PCI device passthrough(pciback). It's a temporary solution, I will send the formal fix for v3.20 and it has passed tests too. Patch 3 fixes an issue found when reading code. There's no real bug reports related to this issue yet. Great thanks to Konrad and Sander for testing fixes for these regressions.
