This patch introduces new option for kpatch-build script "--cross-compile" which can be used for specifying cross-complier prefix. It allows to build live patches not only on target system, but also on hosts for a target other than the one on which the compiler is running. This patch also adds a new --distro option which introduces ability to override distro name, for example, during cross-compilation build when livepatch modules will be ran on the target which differs from host. Also removed quotes in exec lines, so it is possible to pass multi-component strings like "ccache x86_64-xelinux-linux-" as cross-compiler Signed-off-by: Ruslan Bilovol <rbilovol@cisco.com> Signed-off-by: Oleh Matiusha <oleh.matiusha@globallogic.com>

This PR upstreams two patches already present in OpenEmbedded source tree: https://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-kernel/kpatch/kpatch, ported to the latest version of kpatch. They allow livepatches to be compiled for target that differs from the host.
