The pseries and ppc64 defconfigs have drifted apart over the years. Reduce
some of the differences while still keeping the idea that the ppc64 defconfig
is cross platform but enables fewer features than pseries, eg NR_CPUS is
lower.
Also enable a number of common adapters as modules.

The current PS3 gelic wireless driver has support for wireless
extensions. The original PS3 gelic wireless driver exposed a
dedicated API for a dedicated wpa_supplicant driver. This old
API could be enabled with CONFIG_GELIC_WIRELESS_OLD_PSK_INTERFACE,
however, as this is not being used by any distros, and it is being
removed from the driver and from wpa_supplicant.

Now we have high res timers there is less of a reason for a high HZ value.
Furthermore I think there a few reasons we should reduce HZ to 100:
- Timer interrupt overhead. While this overhead is small, there are
applications that are very sensitive to jitter (eg some HPC apps).
- Issues with the timer wheel code. When coming out of NO_HZ idle we work our
way through the timer code one tick at a time. If we have been idle a long
time, this adds up - I sometimes see milliseconds of time spent in that
loop.
Long term we should fix the timer wheel algorithm, but for now if we reduce
HZ then we reduce the amount of work the timer code has to do when coming
out of idle.

Machines with acenic adapters are rare these days, so we may as well make it
a module. Cramfs is also very rarely used so we can make it a module.

This enables CONFIG_ATA_SFF in the defconfigs that are intended to
work on a G5 powermac, i.e. g5_defconfig and ppc64_defconfig. Since
the support for the SATA cell in the K2 chipset is provided by the
sata_svw.c driver, and that depends on CONFIG_ATA_SFF, we need to turn
that and CONFIG_SATA_SVW back on so we can get to the hard disk on G5s.

This mostly takes the defaults, except that I turned on tickless idle

support and "Fair group CPU scheduler" for the smaller/embedded platforms.

* PCMCIA

* RTC_CLASS
* SATA_MV
* SATA_SIL24
* IP_PNP + NFS_ROOT for diskless booting

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.
