Subject: [PATCH 2/5] KVM: x86: Clean up redundant CC macro definition
Date: Mon, 9 Aug 2021 17:34:07 +0800 [thread overview]
Message-ID: <20210809093410.59304-3-likexu@tencent.com> (raw)
In-Reply-To: <20210809093410.59304-1-likexu@tencent.com>
From: Like Xu <likexu@tencent.com>
With the exception of drivers/dma/pl330.c, the CC macro is defined and used
in {svm, vmx}/nested.c, and the KVM_NESTED_VMENTER_CONSISTENCY_CHECK
macro it refers to is defined in x86.h, so it's safe to move it into x86.h
without intended functional changes.
