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

fc59d2d870 qemu_log_lock/unlock now preserves the qemu_logfile handle.
qemu_log_lock() now returns a handle and qemu_log_unlock() receives a
handle to unlock.  This allows for changing the handle during logging
and ensures the lock() and unlock() are for the same file.

Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock()
calls (and the log("\n")), since the translator can longjmp out of the
loop if it attempts to translate an instruction in an inaccessible page.

90c84c5600 qom/cpu: Simplify how CPUClass:cpu_dump_state() prints
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 *.

bdff8123f2 target/microblaze: Switch to transaction_failed hook
Switch the microblaze target from the old unassigned_access hook
to the transaction_failed hook.

The notable difference is that rather than it being called
for all physical memory accesses which fail (including
those made by DMA devices or by the gdbstub), it is only
called for those made by the CPU via its MMU. For
microblaze this makes no difference because none of the
target CPU code needs to make loads or stores by physical
address.

f7a66e3a86 target-microblaze: Simplify address computation using tcg_gen_addi_i32()
Simplify address computation using tcg_gen_addi_i32().
tcg_gen_addi_i32() already optimizes the case when the
immediate is zero.

No functional change.

d248e1beac target-microblaze: Add Extended Addressing
Add support for Extended Addressing. Load/stores with EA
enabled concatenate two 32bit registers to form an extended
address.

We don't allow users to enable address sizes larger than
32 bits quite yet though. Once the MMU support is in, we'll
turn it on.
