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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJW6E0QAAoJEB7SkWpmfYgCM9EP/Aibi3BAYlv6KeCgLFXxNIyR Y7rA0K5UiJwzQMWmo3xQ4EOvAHVCQ33cVEdXy0zJPLnzQ+GCvaMuD/pxOB+HoZWq qUYdVvNomh7VzZDkbONidjuk4kwNHq8HtOo1bdGlPiXjIWEh3uop/rIShPFsRp9i RVByTE/9TGoDQ9Q6Aakw1GlvT75tZ36ZqwkM2jyzu1a7fmqfkfAJjjDY6gzm3/fJ OVv1SDGwknoTPMZFoAh5iyrzHsShw1l1nZFhP4LiulSUEYv4B1I0YNvzbmY9EkgQ LHg/HChXpDCfQN/68k0W7OX6rYPSNjeiX0Y+kqc9owznA32lxsdSMUHcEnGz/3ZE 2yy0XfGMHYsXaWI514dKp1LceTvWYsuQ+NtYnDzEwMch9YjAJpOkxaJTqoRjD0rI 2yxPamLrF1RP7r0jUw2OiMBBpf/N6NvwbIUJ4ssR87ryA8axNcs8Teeu1lgDjajS Xp2AKP5ViWP+lGdAJBY/fa70nSL6oyrHQlzV/3zAPyrVyhAfOTc5mHamlvzYYSBJ EoHDG1A0diP/E4wdiVNrD2fcKie5Vmp4Ws59OCAM8PwOJRXyRGfVB7PP+Q1DSZlc Tsh0QFjfGQOhS02VEaQPm7A19BYFgpTMgU6YqPOPyqVYALIqzj21Ov7+2VI73FyG ORqEjCAxLVto+3gjN0oD =F67V -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: - 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.
