From: Paul Gortmaker Date: Mon, 09 Jan 2017 23:20:25 +0000 Subject: [PATCH RFC] ia64: export ia64_delay_loop for "allmodconfig" coverage Message-Id: <20170109232025.18859-1-paul.gortmaker@windriver.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-kernel@vger.kernel.org Cc: Paul Gortmaker , Tony Luck , Fenghua Yu , Al Viro , linux-ia64@vger.kernel.org Currently we see: ERROR: "ia64_delay_loop" [drivers/spi/spi-thunderx.ko] undefined! ERROR: "ia64_delay_loop" [drivers/net/phy/mdio-cavium.ko] undefined! ...on ia64 allmodconfig builds. While it is true nobody would ever load/use these !ia64 drivers on ia64 kit, they probably won't be the only ones enabled via COMPILE_TEST or non-strict dependencies as time goes on. So just export the symbol, right from the assembly file, now that we can do that.
