Subject: [kvm-unit-tests PATCH v7 06/11] io: Separate overrides of virt_to_phys() and phys_to_virt()
Date: Thu,  5 May 2016 16:26:39 +0200	[thread overview]
Message-ID: <7a7af5609f97d67eca003ba36dd26884593af7e9.1462457467.git.agordeev@redhat.com> (raw)
In-Reply-To: <cover.1462457467.git.agordeev@redhat.com>

Generic implementations of virt_to_phys() and phys_to_virt()
are currently covered by a single "virt_to_phys" macro.
Introduce additional macro "phys_to_virt" to allow separate
overrides.
