Subject: [GIT PULL] libnvdimm for 4.6
Hi Linus, please pull from...
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-4.6
...to receive the libnvdimm update for 4.6.
This has appeared in -next with no reported issues, and a test merge
with latest master passes the regression tests. Note that this
includes development that was based on the tip/core/resources branch
which you merged yesterday. The post merge diffstat is cleaner than
the 6e2452dff444..libnvdimm-for-4.6 diffstat that "git request-pull"
picked.

Merge branch 'for-4.6/pfn' into libnvdimm-for-next (2016-03-09 17:15:43 -0800)
----------------------------------------------------------------
libnvdimm for 4.6
1/ Asynchronous address range scrub:
Given the capacities of next generation persistent memory devices a
scrub operation to find all poison may take 10s of seconds. We want
this scrub work to be done asynchronously with the rest of system
initialization, so we move it out of line from the NFIT probing, i.e.
acpi_nfit_add().
2/ Clear poison:
ACPI 6.1 introduces the ability to send "clear error" commands to the
ACPI0012:00 device representing the root of an "nvdimm bus". Similar to
relocating a bad block on a disk, this support clears media errors in
response to a write.
3/ Persistent memory resource tracking:
A persistent memory range may be designated as simply "reserved" by
platform firmware in the efi/e820 memory map. Later when the NFIT
driver loads it discovers that the range is "Persistent Memory". The
NFIT bus driver inserts a resource to advertise that "persistent"
attribute in the system resource tree for /proc/iomem and
kernel-internal usages.
4/ Miscellaneous cleanups and fixes:
Workaround section misaligned pmem ranges when allocating a struct page
memmap, fix handling of the read-only case in the ioctl path, and clean
up block device major number allocation.
