nfit: move to nfit/ sub-directory With the arrival of x86-machine-check support the nfit driver will add a (conditionally-compiled) source file. Prepare for this by moving all nfit source to drivers/acpi/nfit/. This is pure code movement, no functional changes.

acpi/nfit, libnvdimm: Introduce nvdimm_security_ops Some NVDIMMs, like the ones defined by the NVDIMM_FAMILY_INTEL command set, expose a security capability to lock the DIMMs at poweroff and require a passphrase to unlock them. The security model is derived from ATA security. In anticipation of other DIMMs implementing a similar scheme, and to abstract the core security implementation away from the device-specific details, introduce nvdimm_security_ops. Initially only a status retrieval operation, ->state(), is defined, along with the base infrastructure and definitions for future operations.

nfit: do an ARS scrub on hitting a latent media error When a latent (unknown to 'badblocks') error is encountered, it will trigger a machine check exception. On a system with machine check recovery, this will only SIGBUS the process(es) which had the bad page mapped (as opposed to a kernel panic on platforms without machine check recovery features). In the former case, we want to trigger a full rescan of that nvdimm bus. This will allow any additional, new errors to be captured in the block devices' badblocks lists, and offending operations on them can be trapped early, avoiding machine checks. This is done by registering a callback function with the x86_mce_decoder_chain and calling the new ars_rescan functionality with the address in the mce notificatiion. Cc: Rafael J.
