For reference, it was introduced by:
commit be7773268d98176489483a315d3e2323cb0615b9
Author: Wanpeng Li <wanpen...@tencent.com>
Date: Fri Feb 9 06:15:25 2018 -0800
target-i386: add KVM_HINTS_DEDICATED performance hint
Add KVM_HINTS_DEDICATED performance hint, guest checks this feature bit
to determine if they run on dedicated vCPUs, allowing optimizations such
as usage of qspinlocks.
Sorry for not including a "Fixes:" tag in the commit message. If
you think it's worth it, I can redo the pull request with it.
