[GIT PULL] libnvdimm for 4.4

[Williams, Dan J]

Hi Linus, please pull from...

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
 tags/libnvdimm-for-4.4

...to receive the libnvdimm update for 4.4.  Outside of the new ACPI-NFIT hot-add support this pull request is more notable for what it does not contain, than what it does. There were a handful of development topics this cycle, dax get_user_pages, dax fsync, and raw block dax, that need more more iteration and will wait for 4.5.

The patches to make devm and the pmem driver NUMA aware have been in
-next for several weeks.  The hot-add support has not, but is contained
to the NFIT driver and is passing unit tests.  The coredump support is
straightforward and was looked over by Jeff.  All of it has received a
0day build success notification across 107 configs.

The following changes since commit 7379047d5585187d1288486d4627873170d0005a:

  coredump: add DAX filtering for FDPIC ELF coredumps (2015-11-09 13:29:54 -0500)

----------------------------------------------------------------
libnvdimm for 4.4:

1/ Add support for the ACPI 6.0 NFIT hot add mechanism to process
   updates of the NFIT at runtime.

2/ Teach the coredump implementation how to filter out DAX mappings.

3/ Introduce NUMA hints for allocations made by the pmem driver, and as
   a side effect all devm allocations now hint their NUMA node by
   default.

----------------------------------------------------------------
