From 2540334adc1c7241a7f91a9cf7ec56776d3f601b Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Wed, 9 Jan 2013 10:47:36 +1100 Subject: powerpc: Remove static branch prediction in 64bit traced syscall path Some distros enable auditing by default which forces us through the syscall trace path. Remove the static branch prediction in our 64bit syscall handler and let the hardware do the prediction.
