Subject: [PATCHv3 4/6] arm64: Add cast for virt_to_pfn
Date: Thu, 17 Nov 2016 17:16:54 -0800 [thread overview]
Message-ID: <1479431816-5028-5-git-send-email-labbott@redhat.com> (raw)
In-Reply-To: <1479431816-5028-1-git-send-email-labbott@redhat.com>
virt_to_pfn lacks a cast at the top level. Don't rely on __virt_to_phys
and explicitly cast to unsigned long.
