This is an RFC for something I was playing with over the weekend to
try and reduce target specific details polluting cpu-exec. In the end
it does get rid of TARGET_I386 #ifdef'ery but I couldn't go further to
just building one version of cpu-exec-user and cpu-exec-softmmu
because there are still per target differences.

Anyway what do people think?

Alex Bennée (10):
  metadata: add .git-blame-ignore-revs
  accel/tcg: move cpu_reloading_memory_map into cpu-exec-softmmu
  accel/tcg: move i386 halt handling to sysemu_ops
  accel/tcg: don't bother with ifdef for CPU_DUMP_CCOP
  accel/tcg: remove the fake_user_interrupt guards
  includes: move irq definitions out of cpu-all.h
  accel/tcg: use QEMU_IOTHREAD_LOCK_GUARD to cover the exit
  accel/tcg: push i386 specific hacks into handle_cpu_interrupt callback
  accel/tcg: re-inline the filtering of virtual IRQs but data driven
  accel/tcg: remove unused includes
