[PATCH v4 00/10] tracing: remove dynamic vcpu state

[Alex Bennée]

Hi Stefan,

The references dynamic vcpu tracing support was removed when the
original TCG trace points where removed. However there was still a
legacy of dynamic trace state to track this in cpu.h and extra hash
variables to track TBs. While the removed vcpu tracepoints are not in
generated code (or helpers) they still bring in a bunch of machinery
to manage the state so I've pulled them out. We keep and rename one
(cpu_reset) to a static trace points which dump vcpu->index as it is
useful to f4bug.

v4 addressed Markus's comments on QAPI bits and other fixes during re-base.

Please queue into your tree.

Alex Bennée (10):
  *-user: remove the guest_user_syscall tracepoints
  trace-events: remove the remaining vcpu trace events
  trace: remove vcpu_id from the TraceEvent structure
  scripts/qapi: document the tool that generated the file
  qapi: make the vcpu parameters deprecated for 8.1
  trace: remove code that depends on setting vcpu
  trace: remove control-vcpu.h
  tcg: remove the final vestiges of dstate
  hw/9pfs: use qemu_xxhash4
  accel/tcg: include cs_base in our hash calculations
