[PATCH v2 0/2] Expose known poison in SPA ranges to the block layer

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

v2:
  - Move poison list walking from pmem to core (Dan)
  - If the pmem namespace starts at an offset, account for that (Dan)
  - Fix a bug in extended status checking for ars_status
  - Remove a duplicate include in pmem.c (only introduced in v1)
  - When doing an ars_status, don't error out if an ARS has not yet
    been performed.
  - When checking if ARS is supported, also check the extended status
    and make sure ARS for persistent memory is supported (as opposed to
    just volatile memory)
  - Print a dev_err message if find_poison fails
  - Collapse patches 2 and 3 into a single patch

This series does a few things:
- Retrieve all known poison in the system physical address (SPA) space
  using ARS (Address Range Scrub) commands to firmware
- Store this poison in a new 'nd_poison' structure
- In pmem, consume the poison list and expose the ranges as bad sectors

This depends on the badblocks series sent out previously.
