It looks like it's ~4 years since we updated some of these, so do a bulk
update.

Verified that the before and after generated configs are exactly the
same.

Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated
result.

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.

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-g5f2365d8 (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.

This updates all the defconfigs in arch/powerpc/configs except iseries
and ps3, which were updated by the preceding commits.

This mostly takes the defaults, except that I turned on tickless idle
and high-resolution timers for everything, and turned off instrumentation
support and "Fair group CPU scheduler" for the smaller/embedded platforms.

When checking out the new NO_HZ support in powerpc, I noticed we never
slept for more than 2 seconds.  It turns out SLAB has a 2 second per cpu
timer that causes this.

After switching to SLUB I see some nice 4 second sleeps which is the
limit on this POWER6 box (the decrementer ticks at 512MHz):

slept 4.19 sec
slept 4.19 sec
slept 4.19 sec
slept 4.19 sec
slept 3.96 sec
slept 3.80 sec
slept 2.99 sec

Since SLUB is now the default and some powerpc defconfigs already enable
it, lets enable SLUB across the board for consistency.  While doing this
I also noticed that the maple defconfig has SLAB debugging enabled which
is sure to make your box nice and slow.  Fix that too.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
