Hi Len,
After merging the idle tree, today's linux-next build (x86_64 allmodconfig) failed like this:
In file included from arch/x86/include/asm/msr.h:131:0, from arch/x86/include/asm/processor.h:20, from arch/x86/include/asm/thread_info.h:23, from include/linux/thread_info.h:54, from arch/x86/include/asm/preempt.h:6, from include/linux/preempt.h:18, from include/linux/smp.h:55, from include/linux/kernel_stat.h:4, from drivers/cpufreq/intel_pstate.c:14: drivers/cpufreq/intel_pstate.c: In function 'core_get_turbo_pstate': drivers/cpufreq/intel_pstate.c:593:9: error: 'MSR_NHM_TURBO_RATIO_LIMIT' undeclared (first use in this function) rdmsrl(MSR_NHM_TURBO_RATIO_LIMIT, value); ^ arch/x86/include/asm/paravirt.h:153:26: note: in definition of macro 'rdmsrl' val = paravirt_read_msr(msr, &_err); \ ^ drivers/cpufreq/intel_pstate.c:593:9: note: each undeclared identifier is reported only once for each function it appears in rdmsrl(MSR_NHM_TURBO_RATIO_LIMIT, value); ^ arch/x86/include/asm/paravirt.h:153:26: note: in definition of macro 'rdmsrl' val = paravirt_read_msr(msr, &_err); \ ^
Caused by commit ce62fbaf893c ("tools/power turbostat: define and dump MSR_TURBO_RATIO_LIMIT2"). Grep is your friend ...
I have used the idle tree from next-20150327 for today.
