[GIT PULL] libnvdimm for 4.6

[Williams, Dan J]

Hi Linus, please pull from...

+AKA- 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. +AKA-Note that this
includes development that was based on the tip/core/resources branch
which you merged yesterday. +AKA-The post merge diffstat is cleaner than
the 6e2452dff444..libnvdimm-for-4.6 diffstat that +ACI-git request-pull+ACI-
picked.

----------------------------------------------------------------
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.+AKAAoA-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+AF8-nfit+AF8-add().

2/ Clear poison:
ACPI 6.1 introduces the ability to send +ACI-clear error+ACI- commands to the
ACPI0012:00 device representing the root of an +ACI-nvdimm bus+ACI-.+AKAAoA-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 +ACI-reserved+ACI- by
platform firmware in the efi/e820 memory map.+AKAAoA-Later when the NFIT
driver loads it discovers that the range is +ACI-Persistent Memory+ACI-.+AKAAoA-The
NFIT bus driver inserts a resource to advertise that +ACI-persistent+ACI-
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.
