Add the boiler-plate for a 'clear error' command based on section
9.20.7.6 "Function Index 4 - Clear Uncorrectable Error" from the ACPI
6.1 specification, and add a reference implementation in nfit_test.

Simulate platform-firmware-initiated and asynchronous scrub results.
This injects poison in the middle of all nfit_test pmem address ranges.

nfit, tools/testing/nvdimm: unify common init for acpi_nfit_desc2016-03-05T20:24:06+00:00Dan Williamsdan.j.williams@intel.com2016-02-19T20:29:32+00:00urn:sha1:a61fe6f7902ecaa89d5e6c709490fc4324927134
The nvdimm unit test infrastructure performs its own initialization of
an acpi_nfit_desc to specify test overrides over the native
implementation. Make it clear which attributes and operations it is
overriding by re-using acpi_nfit_init_desc() as a common starting point.

libnvdimm, nfit: centralize command status translation2016-03-05T20:24:06+00:00Dan Williamsdan.j.williams@intel.com2016-02-13T01:01:11+00:00urn:sha1:aef25338226660cdd4df908c2eff1abdcfca65e5
The return value from an 'ndctl_fn' reports the command execution
status, i.e. was the command properly formatted and was it successfully
submitted to the bus provider. The new 'cmd_rc' parameter allows the bus
provider to communicate command specific results, translated into
common error codes.
Convert the ARS commands to this scheme to:
1/ Consolidate status reporting
2/ Prepare for for expanding ars unit test cases
3/ Make the implementation more generic

ACPI 6.1 clarifies that "The system shall include an NVDIMM Control

libnvdimm, tools/testing/nvdimm: fix 'ars_status' output buffer sizing2016-02-19T23:21:52+00:00Dan Williamsdan.j.williams@intel.com2016-02-19T23:21:14+00:00urn:sha1:747ffe11b440ef9ea752888806d3aac677ca52a4
Use the output length specified in the command to size the receive
buffer rather than the arbitrary 4K limit.
This bug was hiding the fact that the ndctl implementation of
ndctl_bus_cmd_new_ars_status() was not specifying an output buffer size.

A dma_addr_t is potentially smaller than a phys_addr_t on some archs.
Don't truncate the address when doing the pfn conversion.

all manufactured NFITs supplied by the test framework. Also, supply
valid response data for ars_status.
