      The current Linux implementation is flawed. It only works - if the user chooses to use one of the few kernels selected - as base for the kernel-headers. While the Makefile seems to have - hooks, allowing the developer to specify whatever version he/she - wants in the target/device/*/* Makefiles, the build will fail - if another kernel version is choosen.

      - -

      The reason for this is that the kernel patches are not - applied by the "target/linux/linux.mk" - build script fragment. They are only applied by the - "toolchain/kernel-headers/*.makefile" - build script fragments

      If the kernel-header version and the linux version differs, - there will be two "linux-2.6.X.Y" - directories in - "build_<ARCH>/<>", - each with its own set of patches.

      The solution in the works, is to move the build of Linux to - "project_build_<ARCH>/<project name>/linux-2.6.X.Y" combined with method to configure - which patches can be applied. Possibly, the linux source tree - used to generate the kernel headers will be moved to the - "toolchain_build_<ARCH>" - directory -
