[PATCH 0/3] Expose known poison in SPA ranges to the block layer

[vishal@kernel.org]

From: Vishal Verma <vishal.l.verma@intel.com>

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[1]

This was tested using nfit_test to add poison at specific address ranges.
More testing, specially on NVDIMM-N hardware is much appreciated!
