Matthew hi

Below is a splitout of the patches I sent to Christoph.
Christoph in his turn has added more changes.

I would please like to help. What is the breakage you
see with DAX.

I'm routinely testing with DAX so it is a surprise,
Though I'm testing with my version with pages and
__copy_from_user_nocache, and so on.
Or I might have missed it. What test are you failing?

Find patches at:
[web: http://git.open-osd.org/gitweb.cgi?p=pmem.git;a=shortlog;h=refs/tags/PMEM-SPLITOUT-4.0-rc5]
[git tag PMEM-SPLITOUT-4.0-rc5 on git://git.open-osd.org / pmem.git]

The interesting list for you:
bc465aa Linux 4.0-rc5
e489c02 x86: add support for the non-standard protected e820 type
8b06a64 SQUASHME: Don't let e820_PMEM section merge emulated segments.

    There were a few changes to what got upstream on top of these 2

a069890 pmem: Initial version of persistent memory driver

    This one already contains changes made by Christoph

d4f6df5 SQUASHME: pmem: Remove getgeo
2f3f1dd SQUASHME: pmem: Streamline pmem driver
c921d23 SQUSHME: pmem: Micro cleaning
bb373a7 SQUASHME: pmem: Remove SECTOR_SHIFT
ad0070e SQUASHME: pmem: Remove "heavily based on brd.c" + Copyright

   This is not the final pmem version that got merged, but these are the changes
   I made which got incorporated.

Thanks
Boaz
