Arm has this documentation about which memory operations support being passed tagged pointers, and which do not: Documentation/arm64/tagged-address-abi.rst
Is the idea that LAM would have something similar, or exactly mirror the arm ABI? It seems like it is the same right now. Should the docs be generalized?
