Based on your result, I decided to re-download Buildroot-2013.08 and run make linux-patch command - no patch installed. I went in and changed my linux configuration from Kernel Version: "Custom tarball" to "3.10.10" and left all other options the same, it attempted to patch the downloaded package with the patch that I have available in my BR2_LINUX_KERNEL_PATCH directory. So I guess now the question is why would it not attempt to install the patch on my "Custom tarball"? Does Buildroot think that since it is a custom tarball that no patches will be required? (I also tried manually editing the .config to change the BR2_LINUX_KERNEL_VERSION from "custom" to "3.10.4" and it attempted to patch the kernel although I would like to have my kernel package under source control so downloading it everytime is not ideal)
