David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
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.

Kim Phillips e3c8a02743 powerpc/mpc8xxx defconfigs - turn off SYSFS_DEPRECATED
a recent fc11 udev update on an 83xx board made root console login
disappear:

  Updating       : udev-141-8.fc11.ppc                                    32/83
udev: starting version 141
udev: deprecated sysfs layout; update the kernel or disable CONFIG_SYSFS_DEPRECATED;
	some udev features will not work correctly

and sure enough, turning off SYSFS_DEPRECATED brings the login prompt back.

Kumar Gala 2bb2e1db90 powerpc: Update defconfigs for FSL PPC boards
Since we are updated defconfigs I went ahead and moved the
asp8347_defconfig under 83xx/ and the mpc8536_ds_defconfig under
85xx/ as that is where they should have been to start with.

Paul Mackerras 43af66e135 [POWERPC] Update defconfigs
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.

Anton Blanchard 309a109255 [POWERPC] Enable SLUB in *_defconfig
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.
