[PATCH v4 00/24] target/arm: Implement FEAT_HAFDBS

[Richard Henderson]

Changes for v4:
  * Rebase on today's target-arm.next pull, including 21 patches.
  * Split AF and DB enablement into two patches.
  * Perform only one atomic update per PTE.
  * Raise Permission fault if atomic update reqd to read-only PTE.
  * More use of S1Translate struct, which is perhaps now mis-named but
    more generally useful/used; suggestions for better naming solicited.
  * Other minor updates per review.
