[PATCH v3 00/21] target-arm: Implement ARMv8.5-MemTag, user mode

[Richard Henderson]

The kernel abi was finally merged into 5.10.

Changes for v3:
  * Split out type changes to separate patches.
  * Add doc comments; tweak alloc so that the !PAGE_VALID case is clear.
  * Do not overlap PAGE_TARGET_2 with PAGE_RESERVED.
  * Use syndrome.h, arm_deliver_fault.
