[GIT PULL] NVDIMM and DAX for 6.5

From: Verma, Vishal L
Date: Fri Jun 30 2023 - 15:18:04 EST


Hi Linus, please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git tags/libnvdimm-for-6.5

... to receive the libnvdimm and DAX update for v6.5.

This is mostly small cleanups and fixes, with the biggest change being the
change to the DAX fault handler allowing it to return VM_FAULT_HWPOISON.

It has appeared in linux-next with no reported issues.

On an operational note, as Dan handed off the branch to me for this cycle, we
missed that the original few commits were inadvertently made on top of a few
CXL commits that went in in the 6.4-rc cycle via the CXL tree.

git-request-pull included these, and hence they appear in the shortlog and
diffstat below, but the actual merge correctly identifies and skips over them.
I kept it as it is to preserve the linux-next soak time, but if I should have
done it differently, please let me know.
