Subject: [PATCH RESEND v13 02/10] KVM: x86/vmx: Make vmx_set_intercept_for_msr() non-static and expose it
Date:   Fri, 30 Oct 2020 11:52:12 +0800
Message-Id: <20201030035220.102403-3-like.xu@linux.intel.com>
In-Reply-To: <20201030035220.102403-1-like.xu@linux.intel.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

To make code responsibilities clear, we may resue and invoke the
vmx_set_intercept_for_msr() in other vmx-specific files (e.g. pmu_intel.c),
so expose it to passthrough LBR msrs later.
