[PATCH v4 0/7] DAX tracepoints, mm argument simplification

[Ross Zwisler]

Andrew,

This contains both my DAX tracepoint code and Dave Jiang's MM argument
simplifications.  Dave's code was written with my tracepoint code as a
baseline, so it seemed simplest to keep them together in a single series.

This series is based on the v4.10-rc3-mmots-2017-01-09-17-08 snapshot.  A
working tree can be found here:

https://git.kernel.org/cgit/linux/kernel/git/zwisler/linux.git/log/?h=mmots_dax_tracepoint

Changes from the previous versions of these patches:
 - Combined Dave's code and mine into a single series.
 - Resolved some minor merge conflics in Dave's patches so they could be
   applied to the latest mmots snapshot.
 - Added Reviewed-by and Acked-by tags to patches as appropriate.

My goal for this series is to get it merged for v4.11.

Thanks,
- Ross
