* kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] Update defconfigsPaul Mackerras2007-12-061-64/+72
| | | | | | | | | | | 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.

* [POWERPC] Enable SLUB in *_defconfigAnton Blanchard2007-10-171-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [POWERPC] Update holly to use new dts wrapping featureMark A. Greer2007-06-251-63/+41
| | | | | | | | | | | | | | | | | | | | The holly support currently has separate rules to wrap its device tree with its zImage. This can now be done automatically without the extra rules so update holly support to use the automatic feature. Signed-off-by: Mark A.

| * [POWERPC] Don't store a command line in the Holly device treeDavid Gibson2007-06-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the Holly device tree includes a bootargs property in /chosen, which gives a commandline. This is somewhat inconvenient, because it means an alternative default command line can't be given in the kernel config - the value obtained from the dts via the bootwrapper will always override CONFIG_CMDLINE. This removes the command line from the dts, and instead puts the same command line as a default in holly_defconfig.
