Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-4.17
...to receive the libnvdimm update for 4.17.
This cycle was was not something I ever want to repeat as there were
several late changes that have only now just settled. Half of the
branch up to commit d2c997c0f145 "fs, dax: use page->mapping to
warn..." have been in -next for several releases. The of_pmem driver
and the address range scrub rework were late arrivals, and the dax work
was scaled back at the last moment.
The of_pmem driver missed a previous merge window due to an oversight.
A sense of obligation to rectify that miss is why it is included for
4.17. It has acks from PowerPC folks. Stephen reported a build failure
that only occurs when merging it with your latest tree, for now I have
fixed that up by disabling modular builds of of_pmem. A test merge with
your tree has received a build success report from the 0day robot over
156 configs.
An initial version of the ARS rework was submitted before the merge
window. It is self contained to libnvdimm, a net code reduction, and
passing all unit tests.
The filesystem-dax changes are based on the wait_var_event()
functionality from tip/sched/core. However, late review feedback showed
that those changes regressed truncate performance to a large degress.
The branch was rewound to drop the truncate behavior change and now
only includes preparation patches and cleanups (with full acks and
reviews). The finalization of this dax-dma-vs-trnucate work will need
to wait for 4.18.
git picked the wait_var_event() baseline for the diffstat, so I also
include the diffstat of the test merge below.
The following changes since commit 3eb2ce825ea1ad89d20f7a3b5780df850e4be274:

Merge branch 'for-4.17/dax' into libnvdimm-for-next (2018-04-09 10:50:17
-0700)
----------------------------------------------------------------
libnvdimm for 4.17
* A rework of the filesytem-dax implementation provides for detection of
unmap operations (truncate / hole punch) colliding with in-progress
device-DMA. A fix for these collisions remains a work-in-progress
pending resolution of truncate latency and starvation regressions.
* The of_pmem driver expands the users of libnvdimm outside of x86 and
ACPI to describe an implementation of persistent memory on PowerPC with
Open Firmware / Device tree.
* Address Range Scrub (ARS) handling is completely rewritten to account for
the fact that ARS may run for 100s of seconds and there is no platform
defined way to cancel it. ARS will now no longer block namespace
initialization.
* The NVDIMM Namespace Label implementation is updated to handle label
areas as small as 1K, down from 128K.
* Miscellaneous cleanups and updates to unit test infrastructure.
