Hi Tony Have you forgot to attach .config? > arch/arm/mach-omap2/built-in.o: In function `omap_enter_idle_coupled': > :(.text+0xb48c): undefined reference to `pm44xx_errata' I assume that .config doesn't have CONFIG_SMP enabled while pm44xx_errata is defined in omap-smp.c. I think it should be a separate patch to move pm44xx_errata somewhere else, so this patch will remain the same. Btw, do we need omap_enter_idle_coupled() in UP? -- Taras Kondratiuk -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
