FYI, I'll try to queue those for my PR today except for:

  scripts/coccinelle: Add cpu_env.cocci script
  --> Still needs review and you mentioned a pending change

  target/arm: Prefer fast cpu_env() over slower CPU QOM cast macro
  --> Needs a rebase and review

  target/hppa: Prefer fast cpu_env() over slower CPU QOM cast macro
  --> Needs a rebase

  target/i386: Prefer fast cpu_env() over slower CPU QOM cast macro
  --> There were unaddressed review comments from Igor

  target/riscv: Prefer fast cpu_env() over slower CPU QOM cast macro
  --> Needs a rebase
