Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl tags/cxl-fixes-6.7-rc6

...to receive a collection of CXL fixes. The touch outside of
drivers/cxl/ is for a helper that allocates physical address space.
Device hotplug tests showed that the driver failed to utilize (skipped
over) valid capacity when allocating a new memory region. Outside of
that, new tests uncovered a small crop of lockdep reports. There is also
some miscellaneous error path and leak fixups that are not urgent, but
useful to cleanup now.

This has been available for the bots to chew on for a few days, but I do
not see it in linux-next. I will need to follow up with Stephen to see
why it missed the 12/15 linux-next. I do not foresee any issues.
