In commit 05a4a952 ("kernel/watchdog: split up config options"),
CONFIG_LOCKUP_DETECTOR was split into two separate config options,
CONFIG_HARDLOCKUP_DETECTOR and CONFIG_SOFTLOCKUP_DETECTOR.

Our defconfigs still have CONFIG_LOCKUP_DETECTOR=y, but that is no longer
user selectable, and we don't mention the new options, so we end up with
none of them enabled.

So update the defconfigs to turn on the new SOFT and HARD options, the
end result being the same as what we had previously.

Although pretty much everyone using powernv is running little endian,
we should still test we can build for big endian. So add a

This reverts commit ec999072 ("powerpc/pseries: Auto-online
hotplugged memory"), and 9dc51281 ("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.

This doesn't have any benefit apart from saving a small amount of 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
