From 48663349813144224d2b1cb6a85a893c2aa901ad Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 2 May 2024 17:48:26 +0200 Subject: [PATCH] kvm: move target-dependent interrupt routing out of kvm-all.c Let hw/hyperv/hyperv.c and hw/intc/s390_flic.c handle (respectively) SynIC and adapter routes, removing the code from target-independent files. This also removes the only occurrence of AdapterInfo outside s390 code, so remove that from typedefs.h.
