tracing: make the trace clocks available generally
Jeremy Fitzhardinge reported this build failure: LD .tmp_vmlinux1 arch/x86/kernel/built-in.o: In function `ds_take_timestamp': git/linux/arch/x86/kernel/ds.c:1380: undefined reference to `trace_clock_global' git/linux/arch/x86/kernel/ds.c:1380: undefined reference to `trace_clock_global' Which is due to !CONFIG_TRACING && CONFIG_X86_DS=y. Expose the trace clock code to CONFIG_X86_DS as well. [ Unfortunately librarizing doesnt work well - ancient architectures with no raw_local_irq_save() primitive break the build. ] Reported-by: Jeremy Fitzhardinge <jeremy@goop.org> LKML-Reference: <49E4413F.7070700@goop.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
