Subject: [Resend PATCH V5 1/10] KVM: Add tlb_remote_flush_with_range callback in kvm_x86_ops
Date: Thu, 8 Nov 2018 22:46:30 +0800 [thread overview]
Message-ID: <20181108144639.11206-1-Tianyu.Lan@microsoft.com> (raw)
From: Lan Tianyu <Tianyu.Lan@microsoft.com>
Add flush range call back in the kvm_x86_ops and platform can use it
to register its associated function. The parameter "kvm_tlb_range"
accepts a single range and flush list which contains a list of ranges.
Signed-off-by: Lan Tianyu <Tianyu.Lan@microsoft.com>

Change since v1:
Change "end_gfn" to "pages" to aviod confusion as to whether
"end_gfn" is inclusive or exlusive.
