From 50824c6eee39eb2d7a60d665b4b245552e852705 Mon Sep 17 00:00:00 2001 From: David Matlack Date: Wed, 2 Nov 2022 11:46:47 -0700 Subject: [PATCH] KVM: selftests: Delete dead ucall code Delete a bunch of code related to ucall handling from smaller_maxphyaddr_emulation_test. The only thing smaller_maxphyaddr_emulation_test needs to check is that the vCPU exits with UCALL_DONE after the second vcpu_run().
