Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

THIN_ARCHIVES option is enabled by default in the kernel configuration
and no one target config disables it. So enable it by default and remove
this symbol from target specific configs to keep them light.

New FUTEX_PI configuration symbol enabled if FUTEX and RT_MUTEX symbols
are enabled. Both of these symbols are enabled by default in the
generic config, so enable FUTEX_PI by default too to keep platform
specific configs minimal.

CONFIG_NVMEM_BCM_OCOTP was added in kernel 4.10 and it is possible to
activate it on the bcm53xx target. Deactivate it by default to fix the
build of the bcm53xx target.
This was found by build bot.

Instead of creating an ubifs file system with format version 5 by
default on empty UBI volumes use the older format 4 by default. This
will make it possible to mount these file systems also on older kernel
versions.
When a user wants to do a sysupgrade from kernel 4.14 to kernel 4.9 the
old kernel has to read the file system created by the more recent kernel
which currently does not work for ubifs.
This fixes the problem by creating file systems which are compatible
with older kernel versions by default.
Kernel 4.14 will still be able to read and write UBI FS file system
version 5, it will just not be used when a ubifs partition is created
implicitly on an empty UBI volume.

While working on a new target (meson), the kernel build failed due to
missing DRM_DEBUG_MM_SELFTEST symbol. This can potentially happen on all
targets that enable DRM drivers in the kernel config or via kmod
packages, so add it to the generic config and remove it from x86
subtarget configs, together with DRM_DEBUG_MM.

While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN
symbol. Move it to generic config instead of defining it for all arm64
and x86/64 targets.
It was only added in 4.0, so not needed in config-3.18.

This adds initial support for kernel 4.14 based on the patches for
kernel 4.9.
In the configuration I deactivated some of the new possible security
features like:
CONFIG_REFCOUNT_FULL
CONFIG_SLAB_FREELIST_HARDENED
CONFIG_SOFTLOCKUP_DETECTOR
CONFIG_WARN_ALL_UNSEEDED_RANDOM
And these overlay FS options are also deactivated:
CONFIG_OVERLAY_FS_INDEX
CONFIG_OVERLAY_FS_REDIRECT_DIR
I activated this:
CONFIG_FORTIFY_SOURCE
CONFIG_POSIX_TIMERS
CONFIG_SLAB_MERGE_DEFAULT
CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED
I am not sure if I did the porting correct for the following patches:
target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch
target/linux/generic/hack-4.14/220-gc_sections.patch
