[4.4-stable PATCH 0/2] libnvdimm: stable fixes for 4.4

[Dan Williams <dan.j.williams@xxxxxxxxx>]

Hi -stable team,

Here is a backport for commit 11e63f6d920d "x86, pmem: fix broken
__copy_user_nocache cache-bypass assumptions", and another block layer
fix that allows the libnvdimm unit tests to run.

I have copied Jens and Jan on the block-layer fix in case they have any
concerns.
