Subject: [PATCH V3 9/10] KVM/MMU: Use tlb range flush in the kvm_age_hva()
Date: Fri, 22 Feb 2019 23:06:36 +0800	[thread overview]
Message-ID: <20190222150637.2337-10-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 tlb range flush in the kvm_age_hva().
If range flush is not available, kvm_flush_remote_tlbs_with_address()
will call kvm_flush_remote_tlbs().
