2796346069 docker: drop QEMU_TARGET check, fallback in EXECUTABLE not set
The addition of QEMU_TARGET was intended to ensure we fall back to
checking for the existence of an image if the build system was not
currently configured to build it. However this breaks the direct use
of the rule for building custom binfmt_misc images. We already check
for EXECUTABLE so let us just use that as a proxy for deciding if we
are just going to check the image exits.

ff1a390296 docker: add expansion for docker-test-FOO to Makefile.include
This allows us to run a particular test on all docker images. For
example:

  make docker-test-unit

Will run the unit tests on every supported image. At the same time
rename docker-test to docker-all-tests to be clearer.

77b08f73c8 docker: Makefile.include don't include partial images
Rename DOCKER_INTERMEDIATE_IMAGES to DOCKER_PARTIAL_IMAGES and add the
incomplete cross compiler images that can build tests but can't build
QEMU itself. We also add debian, debian-bootstrap and the tricode
images to the list.

56c115a953 docker: gracefully skip check_qemu
Not all our images are able to run the tests. Rather than use features
we can just check for the existence and run-ability of gtester. If the

the min_sparse convert parameter can overflow (e.g. -S 1024G)
in the conversion from int64_t to int resulting in a negative
min_sparse parameter. Avoid this by limiting the valid parameters
to sane values. In fact anything exceeding the convert buffer size
is also pointless. While at it also forbid values that are non
multiple of 512 to avoid undesired behaviour. For instance, values
between 1 and 511 were legal, but resulted in full allocation.

1ddc9b98c3 hw/intc/exynos4210_gic: Turn instance_init into realize function
The instance_init function of the "exynos4210.gic" device creates a
new "arm_gic" device and immediately realizes it with qdev_init_nofail().
This will leave a lot of object in the QOM tree during introspection of
the "exynos4210.gic" device, e.g. reproducible by starting QEMU like this:

qemu-system-aarch64 -M none -nodefaults -nographic -monitor stdio

And then by running "info qom-tree" at the HMP monitor, followed by
"device_add exynos4210.gic,help" and finally checking "info qom-tree"
again.

Also note that qdev_init_nofail() can exit QEMU in case of errors - and
this must never happen during an instance_init function, otherwise QEMU
could terminate unexpectedly during introspection of a device.

Since most of the code that follows the qdev_init_nofail() depends on
the realized "gicbusdev", the easiest solution to the problem is to
turn the whole instance_init function into a realize function instead.

07bc425ea3 hw/arm/spitz: Move problematic nand_init() code to realize function
nand_init() does not only create the NAND device, it also realizes
the device with qdev_init_nofail() already. So we must not call
nand_init() from an instance_init function like sl_nand_init(),
otherwise we get superfluous NAND devices in the QOM tree after
introspecting the 'sl-nand' device. So move the nand_init() to the
realize function of 'sl-nand' instead.

9d2b5a58f8 target/arm: Correctly handle overlapping small MPU regions
To correctly handle small (less than TARGET_PAGE_SIZE) MPU regions,
we must correctly handle the case where the address being looked
up hits in an MPU region that is not small but the address is
in the same page as a small region. For instance if MPU region
1 covers an entire page from 0x2000 to 0x2400 and MPU region
2 is small and covers only 0x2200 to 0x2280, then for an access
to 0x2000 we must not return a result covering the full page
even though we hit the page-sized region 1. Otherwise we will
then cache that result in the TLB and accesses that should
hit region 2 will incorrectly find the region 1 information.

Check for the case where we miss an MPU region but it is still
within the same page, and in that case narrow the size we will
pass to tlb_set_page_with_attrs() for whatever the final
outcome is of the MPU lookup.

03a31776e8 hw/sd/bcm2835_sdhost: Fix PIO mode writes
Writes in PIO mode have two requirements:

- A data interrupt must be generated after a write command has been
  issued to indicate that the chip is ready to receive data.
- A block interrupt must be generated after each block to indicate
  that the chip is ready to receive the next data block.

Rearrange the code to make this happen. Tested on raspi3 (in PIO mode)
and raspi2 (in DMA mode).

62aa1d887f monitor: Fix unsafe sharing of @cur_mon among threads
@cur_mon is null unless the main thread is running monitor code, either
HMP code within monitor_read(), or QMP code within
monitor_qmp_dispatch().

Use of @cur_mon outside the main thread is therefore unsafe.

Most of its uses are in monitor command handlers.  These run in the main
thread.

However, there are also uses hiding elsewhere, such as in
error_vprintf(), and thus error_report(), making these functions unsafe
outside the main thread.  No such unsafe uses are known at this time.
Regardless, this is an unnecessary trap.  It's an ancient trap, though.

More recently, commit cf869d5317 "qmp: support out-of-band (oob)
execution" spiced things up: the monitor I/O thread assigns to @cur_mon
when executing commands out-of-band.  Having two threads save, set and
restore @cur_mon without synchronization is definitely unsafe.  We can
end up with @cur_mon null while the main thread runs monitor code, or
non-null while it runs non-monitor code.

We could fix this by making the I/O thread not mess with @cur_mon, but
that would leave the trap armed and ready.

Instead, make @cur_mon thread-local.  It's now reliably null unless the
thread is running monitor code.

25b1ef31db qapi: Make 'allow-oob' optional in SchemaInfoCommand
Making 'allow-oob' optional in SchemaInfoCommand permits omitting it
in the common case.  Shrinks query-qmp-schema's output from 122.1KiB
to 118.6KiB for me.

Note that out-of-band execution is still experimental (you have to
configure the monitor with x-oob=on to use it).

fa97e38eed linux-user/ppc: Implement swapcontext syscall
This allows the tests generated by debian-powerpc-user-cross
to function properly, especially tests/test-coroutine.

Technically this syscall is available to both ppc32 and ppc64,
but only ppc32 glibc actually uses it.  Thus the ppc64 path is
untested.

33143c446e linux-user: fix ELF load alignment error
When we try to use some targets on ppc64, it can happen the target
doesn't support the host page size to align ELF load sections and
fails with:

  ELF load command alignment not page-aligned

Since commit a70daba377 ("linux-user: Tell guest about big host
page sizes") the host page size is used to align ELF sections, but
this doesn't work if the alignment required by the load section is
smaller than the host one.  For these cases, we continue to use the
TARGET_PAGE_SIZE instead of the host one.

I have tested this change on ppc64, and it fixes qemu linux-user for:
  s390x, m68k, i386, arm, aarch64, hppa
and I have tested it doesn't break the following targets:
  x86_64, mips64el, sh4
mips and mipsel abort, but I think for another reason.

In AdvSIMD we can only do 32x32 integer multiples although SVE is
capable of larger 64 bit multiples. As a result we can end up
generating invalid opcodes. Fix this by only reprting we can emit
mul vector ops if the size is small enough.
