2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
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.

2010-04-19powerpc/mpc8xxx defconfigs - turn off SYSFS_DEPRECATEDKim Phillips
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.

unset CONFIG_PCI_LEGACY in the defconfigs as none of them enable ISDN drivers which seem to be the only place we are using pci_find_device Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-08-21powerpc: Update defconfigs for FSL PPC boardsKumar Gala
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. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-12-06[POWERPC] Update defconfigsPaul Mackerras
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.

2007-10-17[POWERPC] Enable SLUB in *_defconfigAnton Blanchard
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.
