For consideration:
* Add NVDIMM support - Enables greater testing, mambo device.
* Add IPv6 support built in + additional modules - Because it's 2018 maan.
* Add DEFERRED_STRUCT_PAGE_INIT - Let's see what breaks.
* Add PPC_MEMTRACE - Small powernv debugfs driver for getting hardware traces.
* Add MEMORY_FAILURE - Machine check exceptions can now drive memory failure.
* Turn on FANOTIFY - This is the current filesystem notification feature.
* Turn on SCOM_DEBUGFS - Handy for hardware/firmware debugging, security risk?
* Turn on async SCSI scanning - Let's see what breaks.
* Add MLX5 driver as a module - Popular demand.
* Add CRYPTO_CRCT10DIF_VPMSUM - POWER8 T10DIF acceleration.
* Make a bunch of USB hid drivers modules.
* Make SCSI SG, SR, and FC modules - FC is huge.
* Make video drivers except AST GPU modules - Also huge.
* Make PCI serial driver a module - Uncommon.
* Make more things modules, NFS FS, RAM disk, netconsole, MS-DOS fs.
* Get rid of /dev/port - Not used.
* Remove PPS and PTP subsystms - Unusual.
* Remove legacy BSD ttys - Long dead.
* Remove IDE - Deprecated and replaced with ATA.
* Remove WIRELESS - Until we get POWER9 laptops.
* Remove RAW - Long deprecated in favour of direct IO.
* Remove floppy, parport, and PS2 input devices - not supported.
* Remove virtio drivers, ballooning - We're host only.
* Remove PPP - Sorry Paulus.

I no longer have a functional version of this board for even the most
basic sanity boot testing, and they have not been available for purchase
for quite some years now.
There is no point in adding a burden to testing coverage that does
walk all the possible defconfigs, so with all the above in mind, it
makes sense to remove it. Of course it will remain in the git history
for anyone who happens to stumble on one and wants to tinker with it.

Highlights:
- Enable support for memory protection keys aka "pkeys" on Power7/8/9 when
using the hash table MMU.
- Extend our interrupt soft masking to support masking PMU interrupts as well
as "normal" interrupts, and then use that to implement local_t for a ~4x
speedup vs the current atomics-based implementation.
- A new driver "ocxl" for "Open Coherent Accelerator Processor Interface
(OpenCAPI)" devices.
- Support for new device tree properties on PowerVM to describe hotpluggable
memory and devices.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO.
- Freescale updates from Scott:
"Contains fixes for CPM GPIO and an FSL PCI erratum workaround, plus a
minor cleanup patch."
As well as quite a lot of other changes all over the place, and small fixes and
cleanups as always.

to try to attempt to make the code easier to handle in the long run, but
no functional change. There's also some tree-wide sysfs attribute
fixups with lots of acks from the various subsystem maintainers, as well
as a handful of other normal fixes and changes.
And finally, some license cleanups for the driver core and sysfs code.
All have been in linux-next for a while with no reported issues.
