To avoid the orphan I/O memory region being added in the /unattached
QOM container, register the PCI device as its owner.

7bbdf0f892 hw/display/xlnx_dp: Replace disabled DPRINTF() by error_report()
DPRINTF() calls are disabled by default, so when unexpected

edcbea008d hw/display/edid: Add missing 'qdev-properties.h' header
When trying to consume the DEFINE_EDID_PROPERTIES() macro
by including "hw/display/edid.h", we get this build failure:

  include/hw/display/edid.h:24:5: error: implicit declaration of
  function ‘DEFINE_PROP_UINT32’ [-Werror=implicit-function-declaration]
     24 |     DEFINE_PROP_UINT32("xres", _state, _edid_info.prefx, 0),    \
        |     ^~~~~~~~~~~~~~~~~~

Headers should be self-contained, and one shouldn't have to
dig to find the missing headers.
In this case "hw/qdev-properties.h" is missing. Add it.

97eeef8aee MAINTAINERS: Add Huacai Chen as fuloong2e co-maintainer
I submitted the MIPS/fuloong2e support about ten years ago, and
after that I became a MIPS kernel developer. Last year, Philippe
Mathieu- Daudé asked me that whether I can be a reviewer of
MIPS/fuloong2e, and I promised that I will do some QEMU work in
the next year (i.e., 2020 and later). I think now (and also in
future) I can have some spare time, so I can finally do some real
work on QEMU/MIPS. And if possible, I hope I can be a co-maintainer
of MIPS/fuloong2e.

cbaf25d1f5 audio: fix wavcapture segfault
Commit 571a8c522e caused the HMP wavcapture command to segfault when
processing audio data in audio_pcm_sw_write(), where a NULL
sw->hw->pcm_ops is dereferenced. This fix checks that the pointer is
valid before dereferincing it. A similar fix is also made in the
parallel function audio_pcm_sw_read().

9c61fcc89a audio/mixeng: fix clang 10+ warning
The code in CONV_NATURAL_FLOAT() and CLIP_NATURAL_FLOAT()
seems to use the constant 2^31-0.5 to convert float to integer
and back. But the float type lacks the required precision and
the constant used for the conversion is 2^31. This is equiva-
lent to a [-1.f, 1.f] <-> [INT32_MIN, INT32_MAX + 1] mapping.

This patch explicitly writes down the used constant. The
compiler generated code doesn't change.

The constant 2^31 has an exact float representation and the
clang 10 compiler stops complaining about an implicit int to
float conversion with a changed value.

A few notes:
- The conversion of 1.f to INT32_MAX + 1 doesn't overflow. The
  type of the destination variable is int64_t.
- At a later stage one of the clip_* functions in
  audio/mixeng_template.h limits INT32_MAX + 1 to the integer
  range.
- The clip_natural_float_* functions in audio/mixeng.c convert
  INT32_MAX and INT32_MAX + 1 to 1.f.

a4c4d46272 xen/9pfs: yield when there isn't enough room on the ring
Instead of truncating replies, which is problematic, wait until the
client reads more data and frees bytes on the reply ring.

Do that by calling qemu_coroutine_yield(). The corresponding
qemu_coroutine_enter_if_inactive() is called from xen_9pfs_bh upon
receiving the next notification from the client.

We need to be careful to avoid races in case xen_9pfs_bh and the
coroutine are both active at the same time. In xen_9pfs_bh, wait until
either the critical section is over (ring->co == NULL) or until the
coroutine becomes inactive (qemu_coroutine_yield() was called) before
continuing. Then, simply wake up the coroutine if it is inactive.

'size' is lesser than the number of frames that are processed
'cnt'.

    int cnt = d->frame_cnt >> 16;
    int size = d->frame_cnt & 0xffff;

if (size < cnt), it results in incorrect calculations leading
to OOB access issue(s). Add check to avoid it.

ed463454ef 9p: Lock directory streams with a CoMutex
Locking was introduced in QEMU 2.7 to address the deprecation of
readdir_r(3) in glibc 2.24. It turns out that the frontend code is
the worst place to handle a critical section with a pthread mutex:
the code runs in a coroutine on behalf of the QEMU mainloop and then
yields control, waiting for the fsdev backend to process the request
in a worker thread. If the client resends another readdir request for
the same fid before the previous one finally unlocked the mutex, we're
deadlocked.

This never bit us because the linux client serializes readdir requests
for the same fid, but it is quite easy to demonstrate with a custom
client.

A good solution could be to narrow the critical section in the worker
thread code and to return a copy of the dirent to the frontend, but
this causes quite some changes in both 9p.c and codir.c. So, instead
of that, in order for people to easily backport the fix to older QEMU
versions, let's simply use a CoMutex since all the users for this
sit in coroutines.

aba53a12bd hw/block/pflash_cfi01: Document use of non-CFI compliant command '0x00'
The command 0x00 is used by this model since its origin (commit
05ee37ebf6). In this commit the command is described with a
amusing '/* ??? */' comment, probably meaning 'FIXME'.

        switch (cmd) {
        case 0x00: /* ??? */
            ...

This comment survived 12 years because the 0x00 value is indeed
not specified by the CFI open standard (as of this commit).

The 'cmd' field is transfered during migration. To keep the
migration feature working with older QEMU version, we have to
take a lot of care with migrated field. We figured out it is
too late to remove a non-specified value from this model
(this would make migration review very complex). It is however
not too late to improve the documentation.

Add few comments to remember this is a special value related
to QEMU, and we won't find information about it on the CFI
spec.

fafe722927 linux-user/arm/signal.c: Drop TARGET_CONFIG_CPU_32
The Arm signal-handling code has some parts ifdeffed with a
TARGET_CONFIG_CPU_32, which is always defined. This is a leftover
from when this code's structure was based on the Linux kernel
signal handling code, where it was intended to support 26-bit
Arm CPUs. The kernel dropped its CONFIG_CPU_32 in kernel commit
4da8b8208eded0ba21e3 in 2009.

QEMU has never had 26-bit CPU support and is unlikely to ever
add it; we certainly aren't going to support 26-bit Linux
binaries via linux-user mode. The ifdef is just unhelpful
noise, so remove it entirely.

45e2813964 linux-user/arm: Reset CPSR_E when entering a signal handler
This fixes signal handlers running with the wrong endianness if the
interrupted code used SETEND to dynamically switch endianness.
