From 16eefbd1ed4ff474807b1aad50bc2f6317fcb9f4 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 3 Aug 2015 11:29:30 +0200 Subject: [PATCH] x86/kconfig: Enable CONFIG_JUMP_LABEL in the defconfigs Enable CONFIG_JUMP_LABEL in the defconfigs, the feature already deals with GCC not having the asm-goto feature so will not break the build on older compilers. Having it enabled generates a faster kernel at very little extra cost since we already include all the code patching code by having KPROBES enabled.
