73d757b714 linux: make vmlinux target available to all architectures
The 'vmlinux' target in the linux build directory is a generic target. It may
not be directly bootable for all architectures, but for projects where a custom
bootloader is used, it can be of value.

Previously, this target was only available for mips architectures. This patch
removes this restriction.

0900c12556 linux: add linux-update-config and linux-update-defconfig targets
In analogy to build targets uclibc-update and busybox-update, add
extra targets to copy the current configuration to the custom
configuration file set in buildroot. These targets facilitate the
work of developers adding support for a specific board.

linux-update-config copies .config directly.
linux-update-defconfig first creates a defconfig and copies that.

13a3afc536 fs/initramfs: refactor with fs/cpio
An initramfs is in fact the same as a cpio archive, but embedded in
the kernel.  So instead of duplicating the cpio infrastructure,
we can simply build images/rootfs.cpio and link that into the
kernel.

be27a7933f rtai, xenomai: use the pre patch hook point
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.

956d4ab0f5 Add xenomai real-time Framework to buildroot
[Fixes by Thomas, including comments from Arnout:
  * Use AUTOTARGETS instead of GENTARGETS

  * Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the
    prepare-kernel.sh script. This allows the arch name to be fixed
    with the usual sed expressions and the quotes to be stripped.

  * Add the --verbose option to prepare-kernel.sh. This allows to get
    some clear error message when no Xenomai patch has been found for
    the current kernel version.

  * Improve the help texts as suggested by Arnout, and remove the
    now useless README file.

  * Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the
    kernel configuration to find out whether SMP is enabled or
    not. This cannot work because: 1) the kernel might be built
    outside of Buildroot and 2) if the kernel is built inside
    Buildroot, it is built *after* Xenomai, so the kernel
    configuration file is typically not yet present.

  * Simplify the ARM subarchitecture selection as suggested by Arnout.

  * Remove the documentation and development files according to
    Buildroot standards (using BR2_HAVE_DOCUMENTATION and
    BR2_HAVE_DEVFILES).

  * Simplify the /etc/ld.so.conf modification logic.

f45f775b4f linux: add support for 3.x and -rc versions
The assumption that all kernels are in
http://www.kernel.org/pub/linux/kernel/v2.6/ is no longer true:
versions 3.x are in separate directories.

We now compute the directory name from the major and minor versions of
the version provided by the user. This assumes that the 3.1 version
will be in a /v3.1/ directory, which we don't know yet because the 3.1
cycle hasn't started yet.

At the same time, we add support for the official -rcX versions.

Patch tested by compiling 3.0-rc6, which Buildroot has successfully
downloaded and built.

b0d446dee4 Improve TARGETS handling for bootloaders and kernel
As the kernel and bootloaders do not use the normal BR2_PACKAGE_*
Kconfig options, their target name was not automatically added to the
global TARGETS variable. Each bootloader .mk and the linux.mk had to
add their own target manually to TARGETS, and the package
infrastructure was making tests on non-existing Kconfig variables.

This commit improves the package infrastructure so that it looks at
BR2_PACKAGE_<pkg> for packages, BR2_TARGET_<pkg> for bootloaders and
at the special BR2_LINUX_KERNEL for the linux package.

This allows to simplify a little bit the bootloaders and linux .mk
files.

726b15f64a Create menu entry to select device creation method
Four methods for the creation of device files in /dev are now
proposed:

 - static method uses device table as before
 - devtmpfs method enables this feature in kernel
 - mdev method adds mdev starting script to the file system
    and selects mdev itself for installation
 - udev method selects udev for installation

All dynamic methods are based on devtmpfs, so one doesn't need to care
about /dev folder.

e88704dfba linux: don't force IPv6 configuration in kernel
As per the discussion at
http://lists.busybox.net/pipermail/buildroot/2010-December/040030.html,
remove the bits that forced the IPv6 configuration in the kernel
depending on the toolchain ability to support (or not) IPv6. You may
have a toolchain with IPv6 support but still don't want to have IPv6
in your kernel.

The only parameters we adjust in the kernel configuration are:

 * ARM EABI, since we got a lot of bug reports regarding misconfigured
   kernel compared to the ABI used by userspace applications.

 * initramfs, since its contents are generated by Buildroot itself
