[Buildroot] [PATCH 0/11 v2] pkg-kernel-module: new infra to ease building kernel modules (branch yem/kernel-modules)

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This series introduces a new infrastructure to help writing packages
that build kernel modules.

Unlike other package infrastrucutre, this new kernel-module
infrastructure is not stand-alone, but is made as a complement to
existing infrastructures, so that packages can build both userland and
kernel modules.

A few packages (9) are converted to use that new infrastructure, and it
greatly simplifies most of them (even allowing us to drop some of our
patches).

Furthermore, as a side effect of converting it to this new inra, it also
fixes the sysdig package, which is cirrently broken because it tries to
build with the host kernel.

Unfortunately, not all packages that build kernel headers were
converted, becasue they use very custom (aka convoluted) Makefiles to
reinvent out-of-tree module building, and it is too much work to fix
them.


Changes v1 -> v2:
  - drop third and fourth args to inner macros (unneeded), fix comments
    about inner macros  (Arnout, Baruch)
  - add LINU_MAKE_ENV  (Arnout)
  - be less verbose, print a single MESSAGE  (Thomas, Arnout)
  - rephrase parts of the manual  (Arnout)
  - explain now-missing variable in ktap  (Thomas)
  - fix crypto-dev  (Doug)
  - fix owl-linux

Regards,
Yann E. MORIN.
