Commit-ID: 16eefbd1ed4ff474807b1aad50bc2f6317fcb9f4 Gitweb: http://git.kernel.org/tip/16eefbd1ed4ff474807b1aad50bc2f6317fcb9f4 Author: Peter Zijlstra <peterz@xxxxxxxxxxxxx> AuthorDate: Mon, 3 Aug 2015 11:29:30 +0200 Committer: Ingo Molnar <mingo@xxxxxxxxxx> CommitDate: Wed, 12 Aug 2015 12:00:39 +0200 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.
