To generate the .config file, I used 'make localmodconfig'. When prompted on new features, I simply went with the default (hit enter). This resulted in the attached config file, which errors out with the following messages: > LD arch/x86/kernel/acpi/built-in.o > CC arch/x86/kernel/apic/apic.o > arch/x86/kernel/apic/apic.c: In function ‘lapic_next_deadline’: > arch/x86/kernel/apic/apic.c:475: error: ‘MSR_IA32_TSC_DEADLINE’ undeclared (first use in this function) > arch/x86/kernel/apic/apic.c:475: error: (Each undeclared identifier is reported only once > arch/x86/kernel/apic/apic.c:475: error: for each function it appears in.) > make[3]: *** [arch/x86/kernel/apic/apic.o] Error 1 > make[2]: *** [arch/x86/kernel/apic] Error 2 > make[1]: *** [arch/x86/kernel] Error 2 > make: *** [arch/x86] Error 2 > > I tracked that down to the header file not being properly included. I wondered also, why is the compiler complaining about the lack of macro definitions instead of complaining about the missing header file? > That is extremely odd. The thing is, your change is actually buggy -- it breaks "make headers_install". Could you do "make arch/x86/kernel/apic/apic.i" and see what version of msr-index.h actually *does* get included? The only reason for putting <uapi/*> in is when there are namespace collisions between uapi and kernel proper... -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-tip-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
