Hi,

This is a grab bag of fixes and clean-ups as we swiftly approach the
soft freeze deadline. The i386 TCG fix came about when re-enabling the
32 bit host build and finding a regression which was masked by KVM's
presence. As a result I decided to disable KVM in the build anyway as
its TCG most likely to get tripped up by 32/64 bit issues.

The plugins fixes are mostly tweaks I made while hunting the above
bug.

I've also included Gustavo's gdbstub MTE support.

The following still need review:

  tests/tcg/aarch64: Add MTE gdbstub tests
  gdbstub: Add support for MTE in user mode
  gdbstub: Use true to set cmd_startswith
  plugins/lockstep: clean-up output
  plugins/lockstep: mention the one-insn-per-tb option
  plugins/lockstep: make mixed-mode safe
  plugins/lockstep: preserve sock_path
  test/plugins: preserve the instruction record over translations
  test/plugin: make insn plugin less noisy by default
  tracepoints: move physmem trace points
  testing: restore some testing for i686
  target/i386: fix gen_prepare_size_nz condition
  tests/lcitool: fix debian-i686-cross toolchain prefix

Akihiko Odaki (2):
  tests/docker: Specify --userns keep-id for Podman
  tests/tcg/arm: Fix fcvt result messages
