coccicheck: add support for requring a coccinelle version
Enable Coccinelle SmPL patches to require a specific version of Coccinelle. In the event that the version does not match we just inform the user, if the user asked to go through all SmPL patches we just inform them of the need for a new version of coccinelle for the SmPL patch and continue on with the rest. This uses the simple kernel scripts/ld-version.sh to create a weight on the version provided by spatch. The -dirty attribute is ignored if supplied, the benefit of scripts/ld-version.sh is it has a long history and well tested. While at it, document the // Options stuff as well. v4: Document // Options and // Requires as well on Documentation/coccinelle.txt. Signed-off-by: Luis R. Rodriguez <mcgrof@kernel.org> Acked-by: Nicolas Palix <nicolas.palix@imag.fr> Signed-off-by: Michal Marek <mmarek@suse.com>
