I use a script which may be the most succinct way to see the change. Here's the core of the script: --- #! /bin/sh # move Xen headers mkdir linux-2.6-xen-sparse/include/xen/ mkdir linux-2.6-xen-sparse/include/linux/xen/ mv linux-2.6-xen-sparse/include/asm-xen/*.h linux-2.6-xen-sparse/include/xen/ mv linux-2.6-xen-sparse/include/asm-xen/linux-public/*.h linux-2.6-xen-sparse/include/linux/xen/ rmdir linux-2.6-xen-sparse/include/asm-xen/linux-public/ find linux-2.6-xen-sparse -name \*.[chS] | while read x;
