[GIT PULL] NVDIMM for 6.19

[Ira Weiny]

Linus,

Please pull from...

  git@xxxxxxxxxxxxxxxxxxx:pub/scm/linux/kernel/git/nvdimm/nvdimm.git tags/libnvdimm-for-6.19

...to get changes for 6.19 for the nvdimm tree.

These are mainly bug fixes and code updates.

There is a new feature to divide up memmap= carve outs and a fix caught in
linux-next for that patch.  Managing memmap memory on the fly for multiple VM's
was proving difficult and Mike provided a driver which allows for the memory to
be better manged.

These have soaked in linux-next without any issues.

Thank you,
Ira Weiny
