I can confirm that the tlb rework does appear to be missing some parts for Power. (Using 2.6.29-rt3 on pseries ppc64) arch/powerpc/kernel/built-in.o:(.toc1+0x4d0): undefined reference to `per_cpu__ppc64_tlb_batch' <...> mm/built-in.o:(.toc1+0xed0): more undefined references to `per_cpu__ppc64_tlb_batch' follow Not clear to me if this is just missing a "DEFINE_PER_CPU_LOCKED" to replace the removed "DEFINE_PER_CPU", (similar to the prior RT patches), or if the tlb rework is more involved. So, I will patiently remain tuned in. :-) Thanks, -Will -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
