From 6da3eced8c5f3b03340b0c395bacd552c4d52411 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Mon, 23 Dec 2019 14:31:47 +0100 Subject: powerpc/spinlocks: Include correct header for static key MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Recently, the spinlock implementation grew a static key optimization, but the jump_label.h header include was left out, leading to build errors: linux/arch/powerpc/include/asm/spinlock.h:44:7: error: implicit declaration of function ‘static_branch_unlikely’ 44 | if (!static_branch_unlikely(&shared_processor)) This commit adds the missing header. mpe: The build break is only seen with CONFIG_JUMP_LABEL=n. Fixes: 656c21d6af5d ("powerpc/shared: Use static key to detect shared processor") Signed-off-by: Jason A.
