Linus Torvalds 8759957b77 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.

     want this scrub work to be done asynchronously with the rest of

     probing, i.e. acpi_nfit_add().

 - Clear poison:
