Yet another cleanup series before respining the "extract TCG
fields from CPUState" series. Before that, we try to clarify
a bit the code around CPU creation. Target specific code is
reduced further. Some intermixed User/System is separated,
making maintenance simpler IMHO. Since my local branch is
quite big, I tried to group here all the generic patches.

Regards,

Phil.

  "target/ppc: Move TCG code from excp_helper.c to tcg-excp_helper.c"

Philippe Mathieu-Daudé (20):
  qemu/compiler: Absorb 'clang-tsa.h'
  user: Extract common MMAP API to 'user/mmap.h'
  gdbstub: Check for TCG before calling tb_flush()
  cpus: Cache CPUClass early in instance_init() handler
  cpus: Keep default fields initialization in cpu_common_initfn()
  accel/kvm: Remove unused 'system/cpus.h' header in kvm-cpus.h
  accel/tcg: Build tcg_flags helpers as common code
  accel/tcg: Restrict tlb_init() / destroy() to TCG
  accel/tcg: Restrict 'icount_align_option' global to TCG
  accel/tcg: Rename 'hw/core/tcg-cpu-ops.h' -> 'accel/tcg/cpu-ops.h'
  accel: Rename 'hw/core/accel-cpu.h' -> 'accel/accel-cpu-target.h'
  accel/accel-cpu-target.h: Include missing 'cpu.h' header
  accel: Forward-declare AccelOpsClass in 'qemu/typedefs.h'
  accel/tcg: Move cpu_memory_rw_debug() user implementation to
    user-exec.c
  cpus: Fix style in cpu-target.c
  cpus: Restrict cpu_common_post_load() code to TCG
  cpus: Have cpu_class_init_props() per user / system emulation
  cpus: Have cpu_exec_initfn() per user / system emulation
  cpus: Register VMState per user / system emulation
  cpus: Build cpu_exec_[un]realizefn() methods once
