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.

Change the default for the built-in IDE on p610/p615/p630 from
ide to libata. libata has better error handling and the drive can
recover when hald does its CD media polling.

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.

- Enable ocfs2, autofs4 and fuse filesystems as modules.
- Enable Kprobes.
- Enable ebus, binfmt_misc, sas attrs, md5 reshape, hvc rtas backend and
  some infiniband options.
- Finally disable debug options: DEBUG_MUTEXES and DEBUG_STACK_USAGE.

The config option SPAN_OTHER_NODES was created so that we could
make pSeries numa layouts work within the DISCONTIG memory model.
Now that DISCONTIG has been replaced by SPARSEMEM, we can eliminate
this option.

I'll be sending a separate patch to Andrew to remove the arch
independent code as pSeries was the only arch that needed this.

This moves the rtas RTC callbacks to rtas-rtc.c in arch/powerpc/kernel,
and kills the rest of arch/ppc64/kernel/rtc.c which was just a duplicate
of the genrtc functionality. Also enable build of genrtc for
CONFIG_PPC64 (it just works are we already have the required callbacks)
and enable it in all defconfigs.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
