Subject: [PATCH V3 4/10] KVM/MMU: Use range flush in sync_page()
Date: Fri, 22 Feb 2019 23:06:31 +0800 [thread overview]
Message-ID: <20190222150637.2337-5-Tianyu.Lan@microsoft.com> (raw)
In-Reply-To: <20190222150637.2337-1-Tianyu.Lan@microsoft.com>
From: Lan Tianyu <Tianyu.Lan@microsoft.com>
This patch is to use range flush to flush tlbs of input struct
kvm_mmu_page in the sync_page(). If range flush is not available,
kvm_flush_remote_tlbs_with_address() will call kvm_flush_remote_tlbs().
Signed-off-by: Lan Tianyu <Tianyu.Lan@microsoft.com>
