Change Details

The prior implementation of xen_intr_resume() was (ab)using the x86 interrupt list as a table of in-use interrupts. Rework this to instead use the xen_intr_port_to_isrc array for this purpose. This removes one more x86-ism from xen_intr.c, a major benefit.

The prior implementation of xen_intr_resume() was wiping xen_intr_port_to_isrc[] and then rebuilding from the x86 interrupt table. Rework to instead wipe the channel numbers (->xi_port) and then scan the table for sources with invalid channels. This removes one more x86-ism from xen_intr.c, a major benefit.
