Subject: [PATCH v4 05/11] Drivers: hv: vmbus: Move virt_to_hvpfn() to hyperv header
Date: Wed, 16 Sep 2020 11:48:11 +0800	[thread overview]
Message-ID: <20200916034817.30282-6-boqun.feng@gmail.com> (raw)
In-Reply-To: <20200916034817.30282-1-boqun.feng@gmail.com>

There will be more places other than vmbus where we need to calculate
the Hyper-V page PFN from a virtual address, so move virt_to_hvpfn() to
hyperv generic header.
