Creating native packages from the kernel tree has multiple advantages: * The package triggers the correct hooks for initramfs generation and bootloader configuration * Uninstallation is complete and also invokes the relevant hooks * New UAPI headers can be installed without any manual bookkeeping The PKGBUILD file is a simplified version of the one used for the downstream Arch Linux "linux" package. Extra steps that should not be necessary for a development kernel have been removed and an UAPI header package has been added.
