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.

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.

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.

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.

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.

Simiar to how kvm_init_vcpu() calls kvm_arch_init_vcpu() to perform
arch-dependent initialisation, introduce kvm_arch_destroy_vcpu()
to be called from kvm_destroy_vcpu() to perform arch-dependent
destruction.
This was added because some architectures (Such as i386)
currently do not free memory that it have allocated in
kvm_arch_init_vcpu().

This commit addresses QEMU Bug #1825311:
mips_cpu_handle_mmu_fault renders all accessed pages executable
It allows finer-grained control over whether the accessed page should
be executable by moving the decision to the underlying map_address
function, which has more information for this.
As a result, pages that have the XI bit set in the TLB and are accessed
for read/write, don't suddenly end up being executable.
Fixes: https://bugs.launchpad.net/qemu/+bug/1825311
Fixes: 2fb58b7374 ('target-mips: add RI and XI fields to TLB entry')

CPUClass method dump_statistics() takes an fprintf()-like callback and
a FILE * to pass to it. Most callers pass fprintf() and stderr.
log_cpu_state() passes fprintf() and qemu_log_file.
hmp_info_registers() passes monitor_fprintf() and the current monitor
cast to FILE *. monitor_fprintf() casts it right back, and is
otherwise identical to monitor_printf().
The callback gets passed around a lot, which is tiresome. The
type-punning around monitor_fprintf() is ugly.
Drop the callback, and call qemu_fprintf() instead. Also gets rid of
the type-punning, since qemu_fprintf() takes NULL instead of the
current monitor cast to FILE *.

Do only virtual addresses comaprisons in LL/SC sequence emulations.
Until this patch, physical addresses had been compared in SC part of
LL/SC sequence, even though such comparisons could be avoided. Getting
rid of them allows throwing away SC helpers and having common SC
implementations in user and system mode, avoiding the need for two
separate implementations selected by #ifdef CONFIG_USER_ONLY.
Correct guest software should not rely on LL/SC if they accesses the
same physical address via different virtual addresses or if page
mapping gets changed between LL/SC due to manipulating TLB entries.
MIPS Instruction Set Manual clearly says that an RMW sequence must
use the same address in the LL and SC (virtual address, physical
address, cacheability and coherency attributes must be identical).
Otherwise, the result of the SC is not predictable. This patch takes
advantage of this fact and removes the virtual->physical address
translation from SC helper.
lladdr served as Coprocessor 0 LLAddr register which captures physical
address of the most recent LL instruction, and also lladdr was used
for comparison with following SC physical address. This patch changes
the meaning of lladdr - now it will only keep the virtual address of
the most recent LL. Additionally, CP0_LLAddr field is introduced which
is the actual Coperocessor 0 LLAddr register that guest can access.

Add translation handlers for four logic MXU instructions.
It should be noted that there is an error in MXU documentation (dated
June 2017) regarding opcodes for this group of instructions. This was
confirmed by running tests on hardware, and also by looking up other
related public source trees (binutils, Android NDK). In initial MXU
patches to QEMU, opcodes for MXU logic instructions were created to
be in accordance with the MXU documentation, therefore the error from
was propagated. This patch corrects that, changing the involved code.
Besides that, as MXU was designed and implemented only for 32-bit
CPUs, corresponding preprosessor conditions were added around MXU
code, which allows more flexible implementation of MXU handlers.

Add generic naming involving generig suffixes OPTN0, OPTN1, OPTN2,

are not quite appropriate for some instructions using optn2.
