[Buildroot] [PATCH 1/5] package: add a PRE_PATCH_HOOKS hook point

[Thomas Petazzoni]

This will be useful to integrate Xenomai and RTAI into Buildroot, so
that they can patch the kernel before the normal patching process
starts.

[Buildroot] [PATCH 2/5] rtai, xenomai: use the pre patch hook point

[Thomas Petazzoni]

The post extract hook point is not really correct as what RTAI and
Xenomai extensions are doing is patching the kernel.

The post patch hook point doesn't work, because RTAI and Xenomai
patches would be applied *after* all other patches, while it sounds
more logical to apply them first, and *then* allow the user to apply
some platform/board specific patches if needed.

[Buildroot] [PATCH 4/5] rtai: Install modules in /lib/modules/<version>/rtai

[Thomas Petazzoni]

The /lib/modules/<version>/kernel/ is completely rewritten by the
kernel module installation, so third party modules should be outside
of this directory.

[Buildroot] [PATCH 5/5] xenomai: install in /usr

[Thomas Petazzoni]

By default, Xenomai installs everything with --prefix=/usr/xenomai,
and passing --prefix=/usr doesn't work because installing Xenomai
headers in /usr/include creates conflicts with other headers. However,
passing --prefix=/usr and --includedir=/usr/include/xenomai just works
fine. This allows to use the default configure command of the
AUTOTARGETS infrastructure, and allows to install the Xenomai headers
and libraries into more usual locations. Furthermore, it allows to
remove the documentation/headers removal hooks, as well as the
ld.so.conf hook since now everything is installed in standard
locations.
