powerpc/8xx: Drop CONFIG_8xx_COPYBACK option CONFIG_8xx_COPYBACK was there to help disabling copyback cache mode for debuging hardware. But nobody will design new boards with 8xx now. All 8xx platforms select it, so make it the default and remove the option. Also remove the Mx_RESETVAL values which are pretty useless and hide the real value while reading code.

powerpc/8xx: Remove CPU6 ERRATA Workaround CPU6 ERRATA affects only MPC860 revisions prior to C.0. Manufacturing of those revisiosn was stopped in 1999-2000. Therefore, it has been almost 20 years since this ERRATA has been fixed in the silicon. This patch removes the workaround for that ERRATA.

powerpc: Update all configs using savedefconfig 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. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

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.

[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.
