Redhat has an article (https://access.redhat.com/kb/docs/DOC-65443) saying the Valencia CPU is supported in RHEL 5.7. I think CentOS 5.7 should also support that, right?
My task is to port the CPU support to CentOS 4 for some reason, so I want to find the exact kernel source patch for valencia CPU. I downloaded the source RPM for centos 5.7, and installed it. But in /usr/src/redhat/SOURCES/, I only see a big kerne-2.6.18-redhat.patch file (about 80 MB) .
I want to find a small patch which just added the necessary support for the CPU. Any suggestions? Thanks.

Where can I find the kernel patch for AMD Valencia CPU
I see 2 immediate problems. One is that CentOS 4 will reach EOL in 4 weeks. Another is the fact that C-4 and C-5 are based on kernel 2.6.9 and kernel 2.6.18, respectively. So, even if you find the patches for C-5, applying them to the C-4 kernel may not be easy (if not impossible).
