powerpc/configs: Remove useless UEVENT_HELPER_PATH

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").

powerpc/configs: Update for CONFIG_NF_CT_PROTO_(SCTP|UDPLITE)=y

In commit a85406afeb3e ("netfilter: conntrack: built-in support for
SCTP"), NF_CT_PROTO_SCTP switched from tristate to bool and became
default y. Similarly in commit 9b91c96c5d1f ("netfilter: conntrack:
built-in support for UDPlite"), NF_CT_PROTO_UDPLITE switched from
tristate to bool and became default y.

We had a few configs which set them to =m, which is no longer valid.
We don't need to change them to =y because both symbols are default y
and are enabled automatically based on the other symbols in the
affected defconfigs.

powerpc/configs: Explicitly drop CONFIG_INPUT_MOUSEDEV

In commit 73d8ef76006b ("Input: mousedev - stop offering PS/2 to userspace by
default") (Jan 2017), CONFIG_INPUT_MOUSEDEV was switched from default y to
default n, with the explanation:

Evdev interface has been available for many years and by now everyone
is switched to using it, so let's stop offering /dev/input/mouseN
and /dev/psaux by default.

We had a number of configs which had it enabled, but going by the above
explanation probably don't need it enabled anymore.

So drop the last remnants of it from our defconfigs.

powerpc: Update all configs using savedefconfig

It looks like it's ~4 years since we updated some of these, so do a bulk
update.

Verified that the before and after generated configs are exactly the
same.

Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated
result.

powerpc: Restore some misc devices to our configs

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.

powerpc: fix linkstation and storcenter compilation breakage

Defining flash partition table in platform code is deprecated, and due to
recent changes linkstation and storcenter do not compile any more with
their default configurations because of undefined references to
physmap_set_partitions(). Instead of fixing them by using the correct
kernel configuration macro in preprocessor conditional, remove partition
table definitions altogether. Instead add support for partition definition
on the command-line and in device tree to the default configurations.

[POWERPC] Enable SLUB in *_defconfig

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.

[POWERPC] Update to linkstation / kurobox support

Linkstation systems capable of running mainline kernels use u-boot as a

Don't guess. Also extend linkstation_defconfig to support the linkstation HS
model with a IT8212 IDE controller and kuroboxHD/HD-HLAN linkstation
models with a tulip ethernet chip. The latter also require a slightly
different .dts file, which is also included with this patch.
