Now that 601 is exclusive from other 6xx, CPU_FTR_601 and
associated fixups are useless.
Drop this feature and use #ifdefs instead.

Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
made default to 'n',
2. It is not recommended (help message: "This should not be used today
[...] creates a high system load") and was kept only for ancient
userland,
3. Certain userland specifically requests it to be disabled (systemd
README: "Legacy hotplug slows down the system and confuses udev").

This reverts the remains of commit b9ef7d6b11c1 ("powerpc: Update
default configurations").
That commit was proceeded by a commit which added a config option to
control use of BOOTX for early debug, ie. PPC_EARLY_DEBUG_BOOTX, and
then the update of the defconfigs was intended to not change behaviour
by then enabling the new config option.
However enabling PPC_EARLY_DEBUG had other consequences, notably
causing us to register the udbg console at the end of udbg_early_init().
This means on a system which doesn't have anything that BOOTX can
use (most systems), we register the udbg console very early but the
bootx code just throws everything away, meaning early boot messages
are never printed to the console.
What we want to happen is for the udbg console to only be registered
later (from setup_arch()) once we've setup udbg_putc, and then all
early boot messages will be replayed.

Commit eb3b705aaed9 ("ALSA: Make CONFIG_SND_OSSEMUL user-selectable")
means we need to set CONFIG_SND_OSSEMUL in our configs, otherwise we

In commit d92d9c3a1448 ("drm: hide legacy drivers with
CONFIG_DRM_LEGACY") CONFIG_R128 was moved behind CONFIG_DRM_LEGACY
meaning it stopped being enabled by pmac32_defconfig. Although no one
has noticed, given this is basically a legacy platform, it seems
anyone who is using it probably still wants this driver. So turn it
back on for now.

In commit 961518259b3b ("rcu: Enable RCU tracepoints by default to aid

which it is for some of our configs).
That in turn causes CONFIG_TREE_RCU_TRACE to be enabled, which selects
CONFIG_DEBUG_FS. The end result is that CONFIG_DEBUG_FS is forced on,
meaning we don't have to enable it in some of our configs.

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively. However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers. This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:
* testing efforts are divided between two subsystems
* having duplicate drivers for same hardware confuses users
This patch converts pmac32_defconfig to use libata PATA
drivers.

Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop
the serial console from being suspended when the rest of the machine goes
to sleep. This is incredibly useful for debugging power management-related
things; however, having it as a compile-time option has proved to be
incredibly inconvenient for us (OLPC). There are plenty of times that we
want serial console to not suspend, but for the most part we'd like serial
console to be suspended.
This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel
boot parameter (no_console_suspend). By default, the serial console will
be suspended along with the rest of the system; by passing
'no_console_suspend' to the kernel during boot, serial console will remain
alive during suspend.
For now, this is pretty serial console specific; further fixes could be
applied to make this work for things like netconsole.

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 patch fixes the front-LED Kconfig issues I introduced while
creating it. Apparently having a dependency isn't enough to have the
select not evaluated or something like that.
The patch also changes the default configuration for pmac32 select the
default for the LED to be the IDE trigger. While I was at it, I
completely updated the defconfig and also added snd-aoa to it.

Some updates to the pmac32_defconfig to make it more useful:
- Enable LSF (large single files) since we enable LBD (large block devices)
- Enable IPSEC related options
- Enable remaining raid/dm options as modules
- Disable eth1394, I doubt any has that hardware and it has a nasty habit of
auto loading first and skewing network device numbering
- Enable dummy and tun as modules, always useful to have them around
- Enable EHCI, no wonder my usb2 disk was so slow
- Enable USB storage
- Enable ext3 acls
- Disable autofs and enable autofsv4 instead
- Enable nfs v3/v4 client and server. Dont want to be left in the dark ages
of pre v3
- Enable all crypto as modules, things like cryptsetup want some of them
I havent enabled the BCM43xx, perhaps we should now?
