Subject: [PATCH rdma-next v2 02/20] drm/i915: Move u64-to-ptr helpers to general header
Date: Sun, 17 Jun 2018 12:59:48 +0300 [thread overview]
Message-ID: <20180617100006.30663-3-leon@kernel.org> (raw)
In-Reply-To: <20180617100006.30663-1-leon@kernel.org>
From: Leon Romanovsky <leonro@mellanox.com>
The macro u64_to_ptr() and function ptr_to_u64() are useful enough
to be part of general header, so move them there and allow RDMA
subsystem reuse them.
