Summary: Linux kernel 3.4.6 fails to build in some cases when CONFIG_NO_HZ is set
Full description: Kernel build using configurations [ 0 ] (mine, trying to build the zen kernel) and [ 1 ] (from someone using slackware) fail to build with this error message when CONFIG_NO_HZ is set: kernel/built-in.o: In function `tick_nohz_stop_sched_tick.isra.9': tick-sched.c:(.text+0x4a3e9): undefined reference to `calc_load_enter_idle' kernel/built-in.o: In function `tick_nohz_idle_exit': (.text+0x4a767): undefined reference to `calc_load_exit_idle' Unsetting CONFIG_NO_HZ solves the issue. However, CONFIG_NO_HZ seems not to be the root of the problem because this configuration [ 2 ] of the zen kernel and Arch's stock kernel [ 3 ] both build with CONFIG_NO_HZ set [ 0 ] https://bugzilla.kernel.org/attachment.cgi?id=75791 [ 1 ] https://bugzilla.kernel.org/attachment.cgi?id=75781 [ 2 ] http://pkgbuild.com/~heftig/linux-zen/config.x86_64 [ 3 ] http://sprunge.us/RHWO PS: It's my first time reporting an issue to this mailing list, so in case the input is missing something, please tell me so I can give a more accurate input. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
