Subject: [PATCH 02/10] KVM: VMX: Move vpid_sync_vcpu_addr() down a few lines
Date: Thu, 20 Feb 2020 12:43:48 -0800 [thread overview]
Message-ID: <20200220204356.8837-3-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200220204356.8837-1-sean.j.christopherson@intel.com>
Move vpid_sync_vcpu_addr() below vpid_sync_context() so that it can be
refactored in a future patch to call vpid_sync_context() directly when
the "individual address" INVVPID variant isn't supported.
No functional change intended.
