From 406663ed61c8ad2b792824af1c1bc0e4faa711c6 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 11 Jan 2016 19:41:14 +0100 Subject: [PATCH] ARM: shmobile: defconfig: Do not enable CONFIG_CPU_BPREDICT_DISABLE Do not disable branch prediction, as this has a big performance impact. After re-enabling branch prediction, __loop_delay() runs 16 (Cortex A15) or 11 (Cortex A9) times faster than before.
