On a successful address translation instruction, PAR is supposed to
contain cacheability and shareability attributes determined by the
translation. We previously returned 0 for these bits (in line with the
general strategy of ignoring caches and memory attributes), but some
guest OSes may depend on them.

This patch collects the attribute bits in the page-table walk, and
updates PAR with the correct attributes for all LPAE translations.
Short descriptor formats still return 0 for these bits, as in the
prior implementation.

All the case where we do special handling of ctrl-alt-X exit the
event handling using a "return" statement, so we can simply allow

the now-spurious "else".

The Makefile attempts to optimize the handling of submodules by using MAKELEVEL
to only check the submodule status when running from the top level make
invokation. This causes problems for people who are using a makefile of their
own to in turn invoke QEMU's makefile, as MAKELEVEL is already set to 1 (or
more) when QEMU's makefile runs.

This optimization should not really be needed, since the git-submodule.sh
script is already used to detect if a submodule update is required. This by
removing the MAKELEVEL check, we at most add an extra 'git-submodule.sh status'
call to each make level, the overhead of which is lost in noise of building
QEMU.

We short circuit the git submodule update when passed an empty module list.
This accidentally causes the 'status' command to write to the status file. The

writing of the status file.

If going back in time in git history, across a commit that introduces a new
submodule, the 'git-submodule.sh' script will fail, causing rebuild to fail.

This is because config-host.mak contains a GIT_SUBMODULES variable that lists
a submodule that only exists in the later commit. config-host.mak won't get
repopulated until config.status is invoked, but make won't get this far due to
the submodule error.

This change makes 'git-submodule.sh' check whether each module is known to git
and drops any which are not present. A warning message will be printed when any
submodule is dropped in this manner.

Some people building QEMU use VPATH builds where the source directory is on a
read-only volume. In such a case 'scripts/git-submodules.sh update' will always
fail and users are required to run it manually themselves on their original
writable source directory.

While this is already supported, it is nice to give users a command line flag
to configure to permanently disable automatic submodule updates, as it means
they won't get hard to diagnose failures from git-submodules.sh at an arbitrary
later date.

This patch thus introduces a flag '--disable-git-update' which will prevent
'make' from ever running 'scripts/git-submodules.sh update'. It will still run
the 'status' command to determine if a submodule update is needed, but when it
does this it'll simply stop and print a message instructing the developer what
todo. eg

$ ./configure  --target-list=x86_64-softmmu --disable-git-update
...snip...

$ make
  GEN     config-host.h
  GEN     trace/generated-tcg-tracers.h
  GEN     trace/generated-helpers-wrappers.h
  GEN     trace/generated-helpers.h

  tcg/s390x: Use constant pool for prologue
  tcg: Allow constant pool entries in the prologue
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Commit ac03ee53 narrowed the scope of the exclusive
region so it only covers when we're executing the TB, not when
we're generating it. However it missed that there is more than
one execution path out of cpu_tb_exec -- if the atomic insn
causes an exception then the code will longjmp out, skipping
the code to end the exclusive region. This causes QEMU to hang
the next time the CPU calls start_exclusive(), waiting for
itself to exit the region.

Move the "end the region" code out to the end of the
function so that it is run for both normal exit and also
for exit-via-longjmp. We have to use a volatile bool flag
to decide whether we need to end the region, because we
can longjump out of the codegen as well as the execution.

(For some reason this only reproduces for me with a clang
optimized build, not a gcc debug build.)

The allwinner code is only needed for the allwinner board (for which
we also have a separate CONFIG_ALLWINNER_A10 config switch), so it
does not make sense that we compile this for all the other boards
that need AHCI, too. Let's move it to a separate file that is only
compiled when CONFIG_ALLWINNER_A10 is set.

This is a legacy artifact from when the sun4m IOMMU implementation was
the only IOMMU available within QEMU.
