Oh, I see, I don't consider non-of platform kernels, I will send V2 patch for this .

Okay, that's what I wanted to know. However, I believe your patch to be incorrect. You delete the assignments to initrd_start and initrd_end in arm_memblock_init(), which will result in non-OF platforms having no initrd. The reason is that OF platforms set initrd_start and initrd_size from the OF code (drivers/of/fdt.c), but ATAG platforms only set our private phys_* versions. The reason I went with phys_* stuff was to permit better verification of the addresses passed - that the addresses were indeed memory locations before passing them through something like __va(). -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
