The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and
leads to some problems:
* cgroup creation is out-of-control
* cgroup name can conflict when pids are looping
* it is not possible to have a single process handling a lot of
namespaces without falling in a exponential creation time
* we may want to create a namespace without creating a cgroup
The ns_cgroup was replaced by a compatibility flag 'clone_children',
where a newly created cgroup will copy the parent cgroup values.
The userspace has to manually create a cgroup and add a task to
the 'tasks' file.
This patch removes the ns_cgroup as suggested in the following thread:
https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html
The 'cgroup_clone' function is removed because it is no longer used.
This is a userspace-visible change. Commit 45531757b4 ("cgroup: notify
ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a
printk warning users that the feature is planned for removal. Since that
time we have heard from XXX users who were affected by this.

This debug option has no overhead other than a slight increase in
kernel size, and makes bug reports more useful. While some end users
may prefer to save the space, as a default on a kernel config aimed
primarily at development on reference boards, it should be enabled.

Even though support for the p5020's on-chip ethernet is not yet upstream,
it is not appropriate to disable all networking support (including
loopback, unix domain sockets, external ethernet devices, etc) in the
defconfig. The networking settings are taken from mpc85xx_smp_defconfig,
minus the drivers for ethernet devices not found on any current e5500
chip.
The other changes are the result of running "make savedefconfig".

Uwe Kleine-König reported:
while working on an defconfig (arm/mx27) I noticed that just updating
it[1] results in removing CONFIG_EEPROM_AT24=y. The reason is that
since commit
v2.6.36-5965-g5f2365d (misc devices: do not enable by default)
MISC_DEVICES isn't enabled anymore by default. So all defconfigs that
have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
problem.
This restores those misc devices to the powerpc defconfigs.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
