package/linux-backports: new package Backports provide drivers released on newer kernels backported for usage on older kernels. There are two versions of linux-backports: one that supports Linux kernels >= 3.0 and one supports even older kernels. We're only packaging the version that supports >= 3.0. linux-backports needs to have access to the kernel's .config to extract information it reintroduces as blind options in generated Kconfig snippets for its own menuconfig. However, Buildroot offers no way to express this kind of dependency. So we need to hand-write a dependency from linux-backports' own .config to linux' .config . Since linux.mk has not already been sourced by the time we source linux-backports.mk, we are missing the definition for LINUX_DIR, so we can not use it our rule. Fortunately, make provides so-called "secondary expansion", by which rules which dependencies include a $$-dereferenced variable wil lbe re-evaluated after all the rest of the Makefiles have been parsed. So, we use that secondary expansion to post-pone evaluation of that dependency so we can use LINUX_DIR. Note: reconstructing LINUX_DIR by hand does not work, because of the custom archives, git tree, or override-srcdir.

The linux-backports package includes many Linux drivers from
recent kernels, backported to older ones.
package/l*: fix wrapping of Config.in help text The check-package script when ran gives warnings on text wrapping on all of these Config files. This patch cleans up all warnings related to the text wrapping for the Config files starting with the letter l in the package directory.

from 3.0.
