[PATCH 0/3] misc updates for Address Range Scrub

[Vishal Verma <vishal.l.verma@intel.com>]

Changes in v3:
- Rename MCE_SCRUB* to HW_ERROR_SCRUB* (Dan)
- Make the default scrub_mode '0' so it doesn't have to be set
  explicitly (Dan)


Changes in v2:
- Change the 'scrub' attribute to only show the number of completed scrubs,
  and start a new one ondemand. (Dan)
- Add a new attribute 'hw_error_scrub' which controls whether or not a full
  scrub will run on hardware memory errors. (Dan)

Patch 1 changes the default behaviour on machine check exceptions to
just adding the error address to badblocks accounting instead of starting
a full ARS. The old behaviour can be enabled via sysfs.

Patch 2 and 3 fix a problem where stale badblocks could show up after an
on-demand ARS or an MCE triggered scrub, or even a namespace disable/enable
cycle because when clearing poison, we didn't clear the internal
nvdimm_bus->poison_list.


Vishal Verma (3):
  nfit: don't start a full scrub by default for an MCE
  pmem: reduce kmap_atomic sections to the memcpys only
  libnvdimm: clear the internal poison_list when clearing badblocks
