Peter Anvin" , Russ Anderson Cc: x86@kernel.org, linux-kernel@vger.kernel.org Subject: [PATCH 6/7] x86/platform/UV: Insure uv_system_init is called when necessary Content-Disposition: inline; filename=uv4_call_uv_system_init Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Move the check to whether this is a UV system that needs initialization from is_uv_system() to the internal uv_system_init() function. This is because on a UV system without a HUB the is_uv_system() returns false. But we still need some specific UV system initialization. See the uv_system_init() for change to a quick check if UV is applicable. This change should not increase overhead since is_uv_system() also called into this same area.
