4376c40ded kvm: introduce kvm_kernel_irqchip_* functions
The KVMState struct is opaque, so provide accessors for the fields
that will be moved from current_machine to the accelerator.  For now
they just forward to the machine object, but this will change.

4f02a06d50 target/mips: Switch to do_transaction_failed() hook
Switch the MIPS target from the old unassigned_access hook to the new
do_transaction_failed hook.

Unlike the old hook, do_transaction_failed is only ever called from
the TCG memory access paths, so there is no need for the "ignore this
if we're using KVM" hack that we were previously using to work around
the way unassigned_access was called for all kinds of memory accesses
to unassigned physical addresses.

The MIPS target does not ever do direct memory reads by physical
address (via either ldl_phys etc or address_space_ldl etc), so the
only memory accesses this affects are the 'normal' guest loads and
stores, which will be handled by the new hook; their behaviour is
unchanged.

3a9576ec98 mips/tcg: Call probe_write() for CONFIG_USER_ONLY as well
Let's call it also for CONFIG_USER_ONLY. While at it, add a FIXME and get
rid of one local variable.

MIPS code probably needs a bigger refactoring in regards of
ensure_writable_pages(), similar to s390x, so for example, watchpoints
can be handled reliably later. The actually accessed addresses should
be probed only, not full pages.

4574664677 target/mips: Hard code size with MO_{8|16|32|64}
Temporarily no-op size_memop was introduced to aid the conversion of
memory_region_dispatch_{read|write} operand "unsigned size" into
"MemOp op".

Now size_memop is implemented, again hard coded size but with
MO_{8|16|32|64}. This is more expressive and avoids size_memop calls.

The memory_region_dispatch_{read|write} operand "unsigned size" is
being converted into a "MemOp op".

Convert interfaces by using no-op size_memop.

After all interfaces are converted, size_memop will be implemented
and the memory_region_dispatch_{read|write} operand "unsigned size"
will be converted into a "MemOp op".

As size_memop is a no-op, this patch does not change any behaviour.

502700d067 target/mips: rationalise softfloat includes
We should avoid including the whole of softfloat headers in cpu.h and
explicitly include it only where we will be calling softfloat
functions. We can use the -types.h in cpu.h for the few bits that are
global. We also move the restore_snan_bit_mode into internal.h and
include -helpers.h there.

54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

db72581598 Include qemu/main-loop.h less
In my "build everything" tree, changing qemu/main-loop.h triggers a
recompile of some 5600 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).  It includes block/aio.h,
which in turn includes qemu/event_notifier.h, qemu/notify.h,
qemu/processor.h, qemu/qsp.h, qemu/queue.h, qemu/thread-posix.h,
qemu/thread.h, qemu/timer.h, and a few more.

Include qemu/main-loop.h only where it's needed.  Touching it now
recompiles only some 1700 objects.  For block/aio.h and
qemu/event_notifier.h, these numbers drop from 5600 to 2800.  For the
others, they shrink only slightly.

650d103d3e Include hw/hw.h exactly where needed
In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

The previous commits have left only the declaration of hw_error() in
hw/hw.h.  This permits dropping most of its inclusions.  Touching it
now recompiles less than 200 objects.

8a9358cc6e migration: Move the VMStateDescription typedef to typedefs.h
We declare incomplete struct VMStateDescription in a couple of places
so we don't have to include migration/vmstate.h for the typedef.
That's fine with me.  However, the next commit will drop
migration/vmstate.h from a massive number of compiles.  Move the
typedef to qemu/typedefs.h now, so I don't have to insert struct in
front of VMStateDescription all over the place then.

64552b6be4 Include hw/irq.h a lot less
In my "build everything" tree, changing hw/irq.h triggers a recompile
of some 5400 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

hw/hw.h supposedly includes it for convenience.  Several other headers
include it just to get qemu_irq and.or qemu_irq_handler.

Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to
qemu/typedefs.h, and then include hw/irq.h only where it's still
needed.  Touching it now recompiles only some 500 objects.
