This will remove some build warnings and doesn't stop us building any
drivers that we were building previously with these configs.

The notable changes here are the enabling of NO_HZ and HIGH_RES_TIMERS.

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.

This make sure that an iseries_defconfig does not inlude
other platforms.

Updating the defconfigs for iseries, pseries, and G5. Sticking with
the defaults, with the following exceptions: I've turned off HW_RANDOM
for all three configs. For G5, I've enabled SND_AOA and friends as
modules; this includes the FABRIC_LAYOUT, ONYX, TAS, TOONIE and
SOUNDBUS* config options.

Adds the ability to disability packet split at compile time and use the legacy receive path on PCI express hardware. Made this a CONFIG option and modified the Kconfig, to reflect the new option.

My patch moving ppc64 RTC to genrtc was supposed to update all
defconfigs, but for some reason, the patch actually posted only had the
pseries one... ouch. This patch properly updates all defconfigs.

Copy default configs into arch/powerpc/configs, rename bpa_defconfig to
cell_defconfig while we're at it.
