Subject: [PATCH v4 03/16] xen/arm: mm: Use gaddr_to_gfn rather than _gfn(paddr_to_pfn(...))
Date: Wed, 21 Feb 2018 14:02:46 +0000 [thread overview]
Message-ID: <20180221140259.29360-4-julien.grall@arm.com> (raw)
In-Reply-To: <20180221140259.29360-1-julien.grall@arm.com>
The construction _gfn(paddr_to_pfn(...)) can be simplified by using
gaddr_to_gfn.
