[GIT PULL v2] libnvdimm/dax fixes for 4.19-rc6

[Williams, Dan J]

Hi Greg, please pull from...

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-fixes-4.19-rc6

...to receive a regression fix and 2 other fixes. Details are in the
tag message. Arguably only the 'address+AF8-space+AF8-operations' fix is urgent
for -rc6, the others can reasonably wait, but I see no reason to hold
them back. This has all appeared in -next with no reported issues.

  device-dax: Add missing address+AF8-space+AF8-operations (2018-09-22 09:07:33 -0700)

libnvdimm/dax for 4.19-rc6

+ACo- (2) fixes for the dax error handling updates that were merged for
v4.19-rc1. My mails to Al have been bouncing recently, so I do not have
his ack but the uaccess change is of the trivial / obviously correct
variety. The address+AF8-space+AF8-operations fixes a regression.

+ACo- A filesystem-dax fix to correct the zero page lookup to be compatible
 with non-x86 (mips and s390) architectures.
