In get_page_addr_code(), if the guest program counter turns out not to
be in ROM or RAM, we can't handle executing from it, and we call
cpu_abort(). This results in the message
  qemu: fatal: Trying to execute code outside RAM or ROM at 0x08000000
followed by a guest register dump, and then QEMU dumps core.

This situation happens in one of two cases:
 (1) a guest kernel bug, where it jumped off into nowhere
 (2) a user command line mistake, where they tried to run an image for
     board A on a QEMU model of board B, or where they didn't provide
     an image at all, and QEMU executed through a ROM or RAM full of
     NOP instructions and then fell off the end

In either case, a core dump of QEMU itself is entirely useless, and
only confuses users into thinking that this is a bug in QEMU rather
than a bug in the guest or a problem with their command line. (This
is a variation on the general idea that we shouldn't assert() on
something the user can accidentally provoke.)

Replace the cpu_abort() with something that explains the situation
a bit better and exits QEMU without dumping core.

(See LP:1062220 for several examples of confused users.)

The AVX2 optimization test assumes that the object format
is ELF and the system has the readelf utility. If this isn't
true then configure might fail or emit a warning (since in
a pipe "foo | bar >/dev/null 2>&1" does not redirect the
stderr of foo, only of bar). Adjust the check so that if
we don't have readelf or don't have an ELF object then we
just don't enable the AVX2 optimization.

The probe we do to determine what flags to use to make the usermode
executables use a non-default text address has some flaws:
 * we run it even if we're not building the user binaries
 * we don't expect "ld --verbose" to fail

The combination of these two results in a harmless but
ugly "ld: unknown option: --verbose" message when running
configure on OSX.

Improve the probe to only run when we need it and to fail
nicely when even the backstop 'ld --verbose' approach fails.

Attempting to cancel a dma_blk_io() request causes an abort(3):

  void bdrv_aio_cancel(BlockAIOCB *acb)
  {
      ...
      while (acb->refcnt > 1) {
          if (acb->aiocb_info->get_aio_context) {
              aio_poll(acb->aiocb_info->get_aio_context(acb), true);
          } else if (acb->bs) {
              aio_poll(bdrv_get_aio_context(acb->bs), true);
          } else {
              abort();
          }
      }
      ...
  }

This happens because DMAAIOCB->bs is NULL and
dma_aiocb_info.get_aio_context() is also NULL.

This patch trivially implements dma_aiocb_info.get_aio_context() by
fetching the DMAAIOCB->ctx field.

  macio: Use blk_drain instead of blk_drain_all
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

When a PCI device lives behind an IOMMU, it should use 'pci_dma_*' family of
functions when any transfer from/to guest memory is required while
'cpu_physical_memory_*' family of functions completely bypass any MMU/IOMMU in
the system.

vmxnet3 in some places was using 'cpu_physical_memory_*' family of functions
which works fine with the default QEMU setup where IOMMU is not enabled but
fails miserably when IOMMU is enabled. This commit converts all such instances
in favor of 'pci_dma_*'

Commit 9d29cdea (rtl8139: port
TallyCounters to vmstate) introduced in incompatibility in the v4
format as it omitted the RxOkMul counter.

There are presumably no users that were impacted by the v4 to v4'
breakage, so increase the save version to 5 and re-add the field,
keeping backward compatibility with v4'.

We can't have a field conditional on the section version in
vmstate_tally_counters since this version checked would not be the
section version (but the version defined in this structure).  So, move
all the fields into the main state structure.

QAPI based and this patch  performs this api conversion since
everything will be using QAPI based sockets in the future. Also add a

When processing MIPSnet I/O port write operation, it uses a
transmit buffer tx_buffer[MAX_ETH_FRAME_SIZE=1514]. Two indices
's->tx_written' and 's->tx_count' are used to control data written
to this buffer. If the two were to be equal before writing, it'd
lead to an OOB write access beyond tx_buffer. Add check to avoid it.
