b3d81b2dec kernel: mitigate cgroups config dependency changes
Memory Resource Controller no longer depends on Resource counters since
Kernel version 4.0.
3.18 is the only still supported version needing Resource counters for
MEMCG, thus declare the dependency only for that version.

02e2548b84 x86: use PARTUUID instead explicitly specifying the device by default
This changes the x86 image generation to match x86_64, using the PARTUUID for
the rootfs instead of explicitly configuring the device.

It unbreaks KVM with VirtIO, which uses /dev/vda2 instead of /dev/sda2.

Tested in QEMU/KVM with VirtIO, VirtualBox and VMware.

b1953bdf27 kernel: enable open by fhandle syscalls
This is needed by many services to function properly and as
all modern distributions got it enabled, it starts to be a
de-facto standard, i.e. user-space starts to silently depend
on it.

This also pulls in EXPORTFS, however, the kernel binary size
increases only a little.
On ARM systems comes down to 800 bytes uncompressed and about
200 bytes compressed size.
On MIPS systems it's about 1.2 kB size increase of the LZMA
compressed kernel.

v2: use menuconfig option instead of just enabling the option

491f3fc048 Support for building an hardened OpenWRT
Introduce configuration options to build an "hardened" OpenWRT.

Options to enable Stack-Smashing Protection, FORTIFY_SOURCE and RELRO
have been introduced.

uClibc makefile now automatically detects if SSP support is necessary.

hostapd makefile has been fixed to use "^" as sed separator since
using a comma was problematic when using "-Wl,-z,now" and the like in
TARGET_CFLAGS.

Currently enabling SSP on user space depends on enabling SSP kernel
side, this is due to the fact that TARGET_CFLAGS are used to build
kernel modules (at least). Suggestions on how to avoid this are welcome.
Using "select" instead of "depends on" doesn't seem to work with choice
entries.

Tested with a lantiq (WBMR) router, GCC 4.8, uClibc and a subset of
the available packages.
Needs to be tested with GCC 4.9 and the remaining packages.
PIE not currently included.

45e3540a3f config: Remove KERNEL_GIT_LOCAL_REPOSITORY option
The GIT_LOCAL_REPOSITORY option adds the --reference argument to the
git clone kernel command line, if KERNEL_GIT_CLONE_URI is set.

This option is intended to speed-up the repo creation by using local
objets rather than downloading it. However, a local repo can be cloned
much faster by setting GIT_LOCAL_REPOSITORY directly to the local tree.

In that case, git clone will bypass the normal "git aware" transport
mechanism and clone the repository by copying and hardlinking objects
rather than downloading it, resulting in a significant speed increase.

That makes the GIT_LOCAL_REPOSITORY option pretty useless so we'll just
remove it and recommand the usage of KERNEL_GIT_CLONE_URI directly.
