Joel, Thank you for the response. I was eventually able to get a kernel built from source and running. Before you responded, I had already tried building all the (non-smp) versions of the kernel for which there are config files in the tarball to which you linked. I couldn't get 2.6.22.9 or 2.6.25.1 to build. I was able to get 2.6.28.4 to build by rolling gcc back to 3.4 (on CentOS, which provided 4.7.2 by default) and 4.4 (on Ubuntu, which provided 4.8.2 by default). However, as mentioned in my second message, 2.6.28.4 wouldn't boot on gem5.
I noticed in the patch files (available at the page to which I linked in my third message) that the patches were labeled for different versions than those of the config files. I tried downloading version 2.6.27.6 of the kernel, and I applied the patch. It built with gcc-3.4. With the config file for 2.6.28.4, it didn't boot, but with the config file for 2.6.22.9, it booted. After I saw your message, I tried building it without the patch, and, as you indicated, it wasn't needed.
