Commit eb3b705aae ("ALSA: Make CONFIG_SND_OSSEMUL user-selectable")
means we need to set CONFIG_SND_OSSEMUL in our configs, otherwise we
lose some of the SND symbols.
And commit 0181307abc ("ALSA: seq: Reorganize kconfig and build")
reorganised things, which causes the churn.

Enable 64K page size and THP. I use ppc64le_defconfig when I need
a single config across guest and host, but having 4K page size
as default is not what I expect. I could move these over to
server.config and merge if ppc64_defconfig is meant for systems
that use 4k pages by default.

In commit e3c4ff6d8c ("EDAC: Remove EDAC_MM_EDAC") CONFIG_EDAC grew
a dependency on CONFIG_RAS. Some of our defconfigs don't have the
latter, which means we lose CONFIG_EDAC, so add CONFIG_RAS to fix
that.

In commit 73d8ef7600 ("Input: mousedev - stop offering PS/2 to userspace by

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

In commit 05a4a95279 ("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.

Highlights include:
- Larger virtual address space on 64-bit server CPUs. By default we use a 128TB
virtual address space, but a process can request access to the full 512TB by
passing a hint to mmap().
- Support for the new Power9 "XIVE" interrupt controller.
- TLB flushing optimisations for the radix MMU on Power9.
- Support for CAPI cards on Power9, using the "Coherent Accelerator Interface
Architecture 2.0".
- The ability to configure the mmap randomisation limits at build and runtime.
- Several small fixes and cleanups to the kprobes code, as well as support for
KPROBES_ON_FTRACE.
- Major improvements to handling of system reset interrupts, correctly treating
them as NMIs, giving them a dedicated stack and using a new hypervisor call
to trigger them, all of which should aid debugging and robustness.
Many fixes and other minor enhancements.

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 ppc64_defconfig to use libata PATA
drivers.

changed CONFIG_SCSI_DH from tristate to bool.

us is invalid, but instead of converting it to =y it leaves it unset.
