It turns out cloud-config uses ISO9660 filesystems to inject
configuration data into cloud images. The cloud-config failures when
ISO9660_FS is not enabled are cryptic, and building it in makes
mainline testing easier, so re-enable it.

This reverts commit ec999072442a ("powerpc/pseries: Auto-online
hotplugged memory"), and 9dc512819e4b ("powerpc: Fix unused function
warning 'lmb_to_memblock'").
Using the auto-online acpability does online added memory but does not
update the associated device struct to indicate that the memory is
online. This causes the pseries memory DLPAR code to fail when trying to
remove a LMB that was previously removed and added back. This happens
when validating that the LMB is removable.
This patch reverts to the previous behavior of calling device_online()
to online the LMB when it is DLPAR added and moves the lmb_to_memblock()
routine out of CONFIG_MEMORY_HOTREMOVE now that we call it for add.
Fixes: ec999072442a ("powerpc/pseries: Auto-online hotplugged memory")

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 pseries_defconfig to use libata PATA
drivers.

Commit 086b91d052eb ("scsi_dh: integrate into the core SCSI code")
changed CONFIG_SCSI_DH from tristate to bool.
Our defconfigs have CONFIG_SCSI_DH=m, which the kconfig machinery warns
us is invalid, but instead of converting it to =y it leaves it unset.
This means we loose the CONFIG_SCSI_DH code and everything that depends
on it.
So convert the values in the defconfigs to =y.

Commit 84ad6e5c added LEDS support for PowerNV platform. Lets
update ppc64_defconfig to pick LEDS driver.
PowerNV LEDS driver looks for "/ibm,opal/leds" node in device
tree and loads if this node exists. Hence added it as 'm'.
Also note that powernv LEDS driver needs NEW_LEDS and LEDS_CLASS
as well. Hence added them to config file.
mpe: Also add them to pseries_defconfig, which is currently also used
for powernv systems.

A working rtc kernel driver is needed so that hwclock can synchronize
system clock to rtc during shutdown/boot. We already have a powernv
platform rtc driver located at drivers/rtc/rtc-opal.c. However it depends
on CONFIG_RTC_CLASS which is disabled by default. Hence the driver isn't
enabled and not compiled for the powernv kernel.
We fix this by enabling rtc class support in pseries defconfig which
enables this driver and compiles it into the pseries kernel. In case
CONFIG_PPC_POWERNV is not enabled we fallback to 'Generic RTC support'
driver which emulates the legacy 'PC RTC driver'.

These two configs should be identical with the exception of big or little
endian.
The big endian version has XMON_DEFAULT turned on while the little endian
has XMON_DEFAULT not set. It makes the most sense for defconfigs not to use
xmon by default, production systems should get back up as quickly as
possible, not sit in xmon.
In the event debugging is required, the option can be enabled or xmon=on
can be specified on commandline.

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

Verified that the before and after generated configs are exactly the

Which begs the question why update them? The answer is that it can be

Pull powerpc updates from Benjamin Herrenschmidt:
"Some highlights in addition to the usual batch of fixes:
- 64TB address space support for 64-bit processes by Aneesh Kumar
- Gavin Shan did a major cleanup & re-organization of our EEH support
code (IBM fancy PCI error handling & recovery infrastructure) which
paves the way for supporting different platform backends, along
with some rework of the PCIe code for the PowerNV platform in order
to remove home made resource allocations and instead use the
generic code (which is possible after some small improvements to it
done by Gavin).
- Uprobes support by Ananth N Mavinakayanahalli
- A pile of embedded updates from Freescale folks, including new SoC
and board supports, more KVM stuff including preparing for 64-bit
BookE KVM support, ePAPR 1.1 updates, etc..."

On POWER6 and POWER7 if the input operand to an instruction is a
denormalised single precision binary floating point value we can take
a denormalisation exception where it's expected that the hypervisor
(HV=1) will fix up the inputs before the instruction is run.
This adds code to handle this denormalisation exception for POWER6 and
POWER7.
It also add a CONFIG_PPC_DENORMALISATION option and sets it in
pseries/ppc64_defconfig.
This is useful on bare metal systems only. Based on patch from Milton
Miller.
