| |
Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-5.7
...to receive the libnvdimm and dax update for this cycle. There were multiple touches outside of drivers/nvdimm/ this round to add cross arch compatibility to the devm_memremap_pages() interface, enhance numa information for persistent memory ranges, and add a zero_page_range() dax operation. This cycle I switched from the patchwork api to Konstantin's b4 script for collecting tags (from x86, PowerPC, filesystem, and device-mapper folks), and everything looks to have gone ok there. This has all appeared in -next with no reported issues.
Given the current environment where one might need to step away on short notice I thought it would be a good idea to highlight to you and others a backup maintainer for libnvdimm. Vishal, has agreed to step in if circumstances make me non-responsive for multiple days. Not expecting anything, just being proactive.

Merge branch 'for-5.7/libnvdimm' into libnvdimm-for-next (2020-04-02 19:55:17 -0700)
---------------------------------------------------------------- libnvdimm for 5.7
- Add support for region alignment configuration and enforcement to fix compatibility across architectures and PowerPC page size configurations.
- Introduce 'zero_page_range' as a dax operation. This facilitates filesystem-dax operation without a block-device.
- Introduce phys_to_target_node() to facilitate drivers that want to know resulting numa node if a given reserved address range was onlined.
- Advertise a persistence-domain for of_pmem and papr_scm. The persistence domain indicates where cpu-store cycles need to reach in the platform-memory subsystem before the platform will consider them power-fail protected.
- Promote numa_map_to_online_node() to a cross-kernel generic facility.
- Save x86 numa information to allow for node-id lookups for reserved memory ranges, deploy that capability for the e820-pmem driver.
- Pick up some miscellaneous minor fixes, that missed v5.6-final, including a some smatch reports in the ioctl path and some unit test compilation fixups.
- Fixup some flexible-array declarations.
