Hi Kumba, I used your patch for 2.6.11 on MIPS kernel, and found that it lost the definition "kernel_physaddr". Could you tell me where is it?

The future is purportedly in the feature known as initramfs. See the file Documentation/early-userpace/README for more details on how that is supposed to work. That said, I tried initramfs a few times, but either due to lack of understanding, or broken support code in 2.6.10, I couldn't get it to properly load an initrd bundled in, so I forward-ported a patch I wrote that originally fixed CONFIG_EMBEDDED_RAMDISK to work with any ABI to 2.6.10, and it worked rather well. I'm sticking with this method until I find more/better docs on how to use initramfs properly. If you're interested, the patch I use can be found here: http://dev.gentoo.org/~kumba/mips/misc/misc-2.6.10-add-ramdisk-back.patch [2.6.10] http://dev.gentoo.org/~kumba/mips/misc/misc-2.6.11-add-ramdisk-back.patch [2.6.11] --Kumba
