[Linux-stable-mirror] [PATCH 3.18] ARM: exynos_defconfig: enable CONFIG_ROOT_NFS and dependencies
Enable CONFIG_ROOT_NFS and dependencies (CONFIG_NFS_*, CONFIG_IP_PNP) in order to be able to boot the Exynos devices with NFS root.
Tested on exynos4412-odroidx2.

Instead, I think it is better to backport mainline commits which synchronizes the history and follows the stable process (mainline -> stable): 19f79ccf6d77409cd138bce8d ("ARM: exynos_defconfig: Enable options to mount a rootfs via NFS") https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
1c1fb9b0c89a2506e556114c813 ("ARM: exynos_defconfig: Enable NFSv4 client") https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...

commit 19f79ccf6d77409cd138bce8db206cdac7fd5ea7 upstream.
This patch enables the options to mount a rootfs over NFS and also support for automatic configuration of IP addresses during boot as needed by NFS.

commit 1c1fb9b0c89a2506e556114c813a606bc1508d49 upstream.
NFS client is already enabled (NFS_FS) and by default it enables clients for version 2 and 3. Enable explicitly the version 4 client to utilize the newer protocol.
The NFS client is especially useful for testing kernel in automated environments (network boot with network file system).
