5409d8bea4 tests/9pfs: fix coverity error in create_local_test_dir()
Coverity wants the return value of mkdir() to be checked:

  /qemu/tests/qtest/libqos/virtio-9p.c: 48 in create_local_test_dir()
  42     /* Creates the directory for the 9pfs 'local' filesystem driver to
  access. */
  43     static void create_local_test_dir(void)
  44     {
  45         struct stat st;
  46
  47         g_assert(local_test_path != NULL);
  >>> CID 1435963:  Error handling issues  (CHECKED_RETURN)
  >>> Calling "mkdir(local_test_path, 511U)" without checking return value.
  This library function may fail and return an error code.
  48         mkdir(local_test_path, 0777);
  49
  50         /* ensure test directory exists now ... */
  51         g_assert(stat(local_test_path, &st) == 0);
  52         /* ... and is actually a directory */
  53         g_assert((st.st_mode & S_IFMT) == S_IFDIR);

So let's just do that and log an info-level message at least, because we
actually only care if the required directory exists and we do have an
existence check for that in place already.

136b7af227 tests/9pfs: fix test dir for parallel tests
Use mkdtemp() to generate a unique directory for the 9p 'local' tests.

This fixes occasional 9p test failures when running 'make check -jN' if
QEMU was compiled for multiple target architectures, because the individual
architecture's test suites would run in parallel and interfere with each
other's data as the test directory was previously hard coded and hence the
same directory was used by all of them simultaniously.

This also requires a change how the test directory is created and deleted:
As the test path is now randomized and virtio_9p_register_nodes() being
called in a somewhat undeterministic way, that's no longer an appropriate
place to create and remove the test directory. Use a constructor and
destructor function for creating and removing the test directory instead.
Unfortunately libqos currently does not support setup/teardown callbacks
to handle this more cleanly.

The constructor functions needs to be in virtio-9p-test.c, not in
virtio-9p.c, because in the latter location it would cause all apps that
link to libqos (i.e. entirely unrelated test suites) to create a 9pfs
test directory as well, which would even break other test suites.

a19d4bc452 ppc patch queue 2020-10-28
Here's the next pull request for ppc and spapr related patches, which
 should be the last things for soft freeze.  Includes:
 
  * Numerous error handling cleanups from Greg Kurz
  * Cleanups to cpu realization and hotplug handling from Greg Kurz
  * A handful of other small fixes and cleanups
 
 This does include a change to pc_dimm_plug() that isn't in my normal
 areas of concern.  That's there as a a prerequisite for ppc specific
 changes, and has an ack from Igor.

dfc00eb7de util: include the target address in socket connect failures
Reporting "Failed to connect socket" is essentially useless for a user
attempting to diagnose failure. It needs to include the target address
details. Similarly when failing to create a socket we should include the
socket family info, so the user understands what particular feature was
missing in their kernel build (IPv6, VSock in particular).

example -- when trying to load a module for a pci device

ef905eff42 sabre: increase number of PCI bus IRQs from 32 to 64
The rework of the sabre IRQs in commit 6864fa3897 "sun4u: update PCI topology to
include simba PCI bridges" changed the IRQ routing so that both PCI and legacy
OBIO IRQs are routed through the sabre PCI host bridge to the CPU.

Unfortunately this commit failed to increase the number of PCI bus IRQs
accordingly meaning that access to the legacy IRQs OBIO (irqnum >= 0x20) would
overflow the PCI bus IRQ array causing strange failures running qemu-system-sparc64
in NetBSD.

ae5643ecc6 hw/display/tcx: Allow 64-bit accesses to framebuffer stippler and blitter
The S24/TCX datasheet is listed as "Unable to locate" on [1].

However the NetBSD revision 1.32 of the driver introduced
64-bit accesses to the stippler and blitter [2]. It is safe
to assume these memory regions are 64-bit accessible.
QEMU implementation is 32-bit, so fill the 'impl' fields.

Michael Lorenz (author of the NetBSD code [2]) provided us with more
information in [3]:

> IIRC the real hardware *requires* 64bit accesses for stipple and
> blitter operations to work. For stipples you write a 64bit word into
> STIP space, the address defines where in the framebuffer you want to
> draw, the data contain a 32bit bitmask, foreground colour and a ROP.
> BLIT space works similarly, the 64bit word contains an offset were to
> read pixels from, and how many you want to copy.
>
> One more thing since there seems to be some confusion - 64bit accesses
> on the framebuffer are fine as well. TCX/S24 is *not* an SBus device,
> even though its node says it is.
> S24 is a card that plugs into a special slot on the SS5 mainboard,
> which is shared with an SBus slot and looks a lot like a horizontal
> UPA slot. Both S24 and TCX are accessed through the Micro/TurboSPARC's
> AFX bus which is 64bit wide and intended for graphics.
> Early FFB docs even mentioned connecting to both AFX and UPA,
> no idea if that was ever realized in hardware though.

1d705e8a5b accel/tcg: Add CPU_LOG_EXEC tracing for cpu_io_recompile()
When using -icount, it's useful for the CPU_LOG_EXEC logging
to include information about when cpu_io_recompile() was
called, because it alerts the reader of the log that the
tracing of a previous TB execution may not actually
correspond to an actually executed instruction. For instance
if you're using -icount and also -singlestep then a guest
instruction that makes an IO access appears in two
"Trace" lines, once in a TB that triggers the cpu_io_recompile()
and then again in the TB that actually executes.

(This is a similar reason to why the "Stopped execution of
TB chain before..." logging in cpu_tb_exec() is helpful
when trying to track execution flow in the logs.)

5057bf9581 scripts/qmp: delete 'qmp' script
This script has not seen a patch that was specifically for this script
since it was moved to this location in 2013, and I doubt it is used. It
uses "man qmp" for its help message, which does not exist. It also
presumes there is a manual page for qmp-XXX, for each defined qmp
command XXX. I don't think that's true.

The format it expects arguments in is something like:

block-dirty-bitmap-add --node=foo --name=bar

and has no capacity to support nested JSON arguments, either.

Most developers use either qmp-shell or socat (or pasting JSON directly
into qmp stdio), so this duplication and additional alternate syntax is
not helpful.

Remove it. Leave a breadcrumb script just in case, to be removed next
release cycle.

c5af3c0d85 cpus: Drop declaration of cpu_remove()
cpu_remove() got superseded by cpu_remove_sync() in commit dbadee4ff4,
but its prototype wasn't removed. We could possibly keep the shorter
cpu_remove() naming but it seems better to highligth that this blocks
until the CPU thread is joined.

Fixes: dbadee4ff4 ("cpus: join thread when removing a vCPU")

018da27970 Makefile: Add *.[ch].inc files to cscope/ctags/TAGS
The code base has some C source and header files that don't get indexed
because their name ends with .inc:

$ git ls-files "*.[ch].inc" | wc -l
66

Add them to the list.
