Subject: [PATCHv2 4/6] arm64: Add cast for virt_to_pfn
Date: Wed,  2 Nov 2016 15:00:52 -0600	[thread overview]
Message-ID: <20161102210054.16621-5-labbott@redhat.com> (raw)
In-Reply-To: <20161102210054.16621-1-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.
