Remove CONFIG_POWER4_ONLY, the option is badly named and only does two
things:
- It wraps the MMU segment table code. With feature fixups there is
little downside to compiling this in.
- It uses the newer mtocrf instruction in various assembly functions.
Instead of making this a compile option just do it at runtime via
a feature fixup.

Uwe Kleine-König reported:
while working on an defconfig (arm/mx27) I noticed that just updating
it[1] results in removing CONFIG_EEPROM_AT24=y. The reason is that
since commit
v2.6.36-5965-g5f2365d (misc devices: do not enable by default)
MISC_DEVICES isn't enabled anymore by default. So all defconfigs that
have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
problem.
This restores those misc devices to the powerpc defconfigs.

pasemi_defconfig hasn't been updated for a year.
Mostly a refresh of defaults, but this also disables 64K pages.

Now that all EEPROM drivers live in the same place, let's harmonize
their symbol names.
Also fix eeprom's dependencies, it definitely needs sysfs, and is no
longer experimental after many years in the kernel tree.

Disable GEN_RTC since it conflicts with the i2c rtc drivers registering,
besides that keep most of the new defaults.

Move electra-ide glue over to the new pata_of_platform framework, and
add the quirks needed to that driver.

Enable MSI now that we have an implementation, and enable CONFIG_MD and
the raid options by default as well.

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.

Update pasemi_defconfig. Add a few missing options for default devices
on electra boards, enable tickless and hrtimers, etc, etc.

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.
