A detailed description of the new formats can be found in the NVMe's NVM Command Set Specification, section 5.2, available at: https://nvmexpress.org/wp-content/uploads/NVM-Command-Set-Specification-1.0b-2021.12.18-Ratified.pdf This series implements one possible new format: the CRC64 guard with 48-bit reference tags. This does not add support for the variable "storage tag" field, or any potential hardware acceleration. Changes since v3: - Replaced lower_48_bits() macro with inline function, and replaced 0xffffffffffffull with the equivalent (1ull << 48) - 1 - Replaced crc64 test module with new entry in crypto/testmgr.c - Renamed nvme_ function prefixes with ext_pi_ - Placed bit inversion within crc64 calculation rather than rely on the caller to pass in an inverted initial value. This is necessary to update the crc value when its buffer is discontiguous, or updated in chunks. - Removed 'inline' from nvme driver's ref tag setup. - Added Review's for unchanged patches, removed reviews for the ones that changed. - lib/Kconfig dependency fix - Dropped the x86_64 PCLMULQDQ accelerated calculation. This task will be completed by people more experienced in this area, so expect a follow up soon.
