Revision 6 of the MIPS architecture is a major revision of the MIPS architecture which does away with many of original sins of the architecture such as branch delay slots. This and other changes in R6 require major changes throughout the entire MIPS core architecture code and make up for the lion share of this pull request. - finally some preparatory work for eXtendend Physical Address support, which allows support of up to 40 bit of physical address space on 32 bit processors" [ Ahh, MIPS can't leave the PAE brain damage alone.

Newer specifications provide other ways to translate based on the device's version can be used to create unique identifiers. Version 1.1 provides an EUI64 field that uniquely identifies each namespace, and 1.2 added the longer NGUID field for the same reason. Both follow the IEEE EUI format and readily translate to the SCSI device identification EUI designator type 2h. For devices implementing either, the translation will use this type, defaulting to the EUI64 8-byte type if implemented then NGUID's 16 byte version if not. If neither are provided, the 1.0 translation is used, and is updated to use the SCSI String format to guarantee a unique identifier. Knowing when to use the new fields depends on the nvme controller's revision. The NVME_VS macro was not decoding this correctly, so that is fixed in this patch and moved to a more appropriate place. Since the Identify Namespace structure required an update for the NGUID field, this patch adds the remaining new 1.2 fields to the structure.

Namespace formats that are unusable will have disk capacity set to 0, but a handle to the block device is created to simplify device management. A namespace is not usable when the format requires host interleave block and metadata in single buffer, has no provisioned storage, or has better data but failed to register with blk integrity. The namespace has to be scanned in two phases to support separate metadata formats. The first establishes the sector size and capacity prior to invoking add_disk. If metadata is required, the capacity will be temporarilly set to 0 until it can be revalidated and registered with the integrity extenstions after add_disk completes. The driver relies on the integrity extensions to provide the metadata buffer. NVMe requires this be a single physically contiguous region, so only one integrity segment is allowed per command. If the metadata is used for T10 PI, the driver provides mappings to save and restore the reftag physical block translation. The driver provides no-op functions for generate and verify if metadata is not used for protection information. This way the setup is always provided by the block layer. If a request does not supply a required metadata buffer, the command is failed with bad address. This could only happen if a user manually disables verify/generate on such a disk. The only exception to where this is okay is if the controller is capable of stripping/generating the metadata, which is possible on some types of formats. The metadata scatter gather list now occupies the spot in the nvme_iod that used to be used to link retryable IOD's, but we don't do that anymore, so the field was unused.

Yann Droneaud writes: Note: as offsetof() is used to retrieve the size of the lower chunk of the response, beware that it only works if the upper chunk is right after, without any implicit padding. And, as the size of the latter chunk is added to the base size, implicit padding at the end of the structure is not taken in account. Both point must be taken in account when extending the uverbs functionalities.
