feafe82cc2 target/mips: Amend CP0 WatchHi register implementation 
WatchHi is extended by the field MemoryMapID with the GINVT instruction.
The field is accessible by MTHC0/MFHC0 in 32-bit architectures and DMTC0/
DMFC0 in 64-bit architectures.

54fc33fdc4 target/mips: semihosting: Remove 'uhi_done' label in helper_do_semihosting() 
The label 'uhi_done' is a simple 'return' call and can
be removed for a bit more clarity in the code.

dcb32f1d8f tcg: Search includes from the project root source directory 
We currently search both the root and the tcg/ directories for tcg
files:

  $ git grep '#include "tcg/' | wc -l
  28

  $ git grep '#include "tcg[^/]' | wc -l
  94

To simplify the preprocessor search path, unify by expliciting the
tcg/ directory.

Patch created mechanically by running:

  $ for x in \
      tcg.h tcg-mo.h tcg-op.h tcg-opc.h \
      tcg-op-gvec.h tcg-gvec-desc.h; do \
    sed -i "s,#include \"$x\",#include \"tcg/$x\"," \
      $(git grep -l "#include \"$x\""); \
    done

7dd547e5ab target/mips: Use cpu_*_mmuidx_ra instead of MMU_MODE*_SUFFIX 
The separate suffixed functions were used to construct
some do_##insn function switched on mmu_idx.  The interface
is exactly identical to the *_mmuidx_ra functions.  Replace
them directly and remove the constructions.

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.

e501824b3f target/mips: Access MemoryRegion with MemOp 
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.
