| |
From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>
Currently, the scripts hard-code arch/x86/boot/bzImage, which does not work well for other architectures. This commit therefore provides a identify_boot_image function that selects the correct bzImage location relative to the top of the Linux source tree. This commit also adds a --bootimage argument that allows selecting some other file, for example, "vmlinux".
