          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: kvm
          Assignee: virtualization_kvm@kernel-bugs.osdl.org
          Reporter: lixiao.yang@intel.com
        Regression: No

Environment:

Host kernel: 5.19.0-rc8

Host OS: rhel8.3

upstream kvm repo: https://git.kernel.org/pub/scm/virt/kvm/kvm.git

branch: next

commit: 19a7cc817a380f7a412d7d76e145e9e2bc47e52f

GCC version: gcc (GCC) 8.3.1 20191121 (Red Hat 8.3.1-5)

Bug Detailed Description:

Error happens when trying to compile upstream kvm selftests.

git clone https://git.kernel.org/pub/scm/virt/kvm/kvm.git
git checkout -b next origin/next
cd kvm/tools/testing/selftests/kvm
make

Expected results:
Successfully build
