Hi Linus, please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/dax-fixes-6.1-rc8

...to receive a few bug fixes around the handling of "Soft Reserved"
memory and memory tiering information. Linux is starting to enounter
more real world systems that deploy an ACPI HMAT to describe different
performance classes of memory, as well the "special purpose" (Linux
"Soft Reserved") designation from EFI. These fixes result from that
testing.

It has all appeared in -next for a while with no known issues.
