cd6b1674d6 docs: Fix botched rST conversion of 'submitting-a-patch.rst'
I completely botched up the merged[0] rST conversion of this document by
accidentally dropping entire hunks (!) of text. :-(  I made it very hard
for reviewers to spot it, as the omitted text was buried deep in the
document.  To fix my hatchet job, I reconverted the "SubmitAPatch"
wiki[1] page from scratch and replaced the existing rST with it, while
making sure I incorporated previous feedback.

In summary, in this reconverted edition:

- I did a careful (to the extent my eyes allowed) para-by-para
  comparison of the wiki and the rST to make sure I didn't omit
  anything accidentally.

- I made sure to work in the cosmetic feedback[2] that Thomas Huth
  pointed out in the merged (and botched) edition:

   - fix the hyperlinks in "Split up long patches"

   - replace ".". with "does not end with a dot" (in "Write a meaningful
     commit message" section)

   - replace "---" with ``---`` so that it doesn't render as an em-dash
     (there were two other occurrences; I fixed those too)

- Use "QEMU" spelling consistently in prose usage

- Add a consistent "refer to git-config" link where appropriate

Thanks to Thomas Huth and Alex Bennée for noticing it on IRC.  And sorry
for my sloppiness.

4825eaae4f Revert "arm: tcg: Adhere to SMCCC 1.3 section 5.2"
This reverts commit 9fcd15b919.

This change turns out to cause regressions, for instance on the
imx6ul boards as described here:
https://lore.kernel.org/qemu-devel/c8b89685-7490-328b-51a3-48711c140a84@tribudubois.net/

The primary cause of that regression is that the guest code running
at EL3 expects SMCs (not related to PSCI) to do what they would if
our PSCI emulation was not present at all, but after this change
they instead set a value in R0/X0 and continue.

We could fix that by a refactoring that allowed us to only turn on
the PSCI emulation if we weren't booting the guest at EL3, but there
is a more tangled problem with the highbank board, which:
 (1) wants to enable PSCI emulation
 (2) has a bit of guest code that it wants to run at EL3 and
     to perform SMC calls that trap to the monitor vector table:
     this is the boot stub code that is written to memory by
     arm_write_secure_board_setup_dummy_smc() and which the
     highbank board enables by setting bootinfo->secure_board_setup

We can't satisfy both of those and also have the PSCI emulation
handle all SMC instruction executions regardless of function
identifier value.

This is too tricky to try to sort out before 6.2 is released;
revert this commit so we can take the time to get it right in
the 7.0 release.

e35574226a nbd/server: Simplify zero and trim
Now that the block layer supports 64-bit operations (see commit
2800637a and friends, new to v6.2), we no longer have to self-fragment
requests larger than 2G, reverting the workaround added in 890cbccb08
("nbd: Fix large trim/zero requests", v5.1.0).

1644cccea5 nbd/server: Don't complain on certain client disconnects
When a client disconnects abruptly, but did not have any pending
requests (for example, when using nbdsh without calling h.shutdown),
we used to output the following message:

$ qemu-nbd -f raw file
$ nbdsh -u 'nbd://localhost:10809' -c 'h.trim(1,0)'
qemu-nbd: Disconnect client, due to: Failed to read request: Unexpected end-of-file before all bytes were read

Then in commit f148ae7, we refactored nbd_receive_request() to use
nbd_read_eof(); when this returns 0, we regressed into tracing
uninitialized memory (if tracing is enabled) and reporting a
less-specific:

qemu-nbd: Disconnect client, due to: Request handling failed in intermediate state

Note that with Unix sockets, we have yet another error message,
unchanged by the 6.0 regression:

$ qemu-nbd -k /tmp/sock -f raw file
$ nbdsh -u 'nbd+unix:///?socket=/tmp/sock' -c 'h.trim(1,0)'
qemu-nbd: Disconnect client, due to: Failed to send reply: Unable to write to socket: Broken pipe

But in all cases, the error message goes away if the client performs a
soft shutdown by using NBD_CMD_DISC, rather than a hard shutdown by
abrupt disconnect:

$ nbdsh -u 'nbd://localhost:10809' -c 'h.trim(1,0)' -c 'h.shutdown()'

This patch fixes things to avoid uninitialized memory, and in general
avoids warning about a client that does a hard shutdown when not in
the middle of a packet.  A client that aborts mid-request, or which
does not read the full server's reply, can still result in warnings,
but those are indeed much more unusual situations.

2e572baf65 ui/vnc-clipboard: fix adding notifier twice
vnc_server_cut_text_caps() is not guaranteed to be called only once.

If it called twice, we finally call notifier_list_add() twice with same
element. Which leads to loopback QLIST. So, on next
notifier_list_notify() we'll loop forever and QEMU stuck.

So, let's only register new notifier if it's not yet registered.

Note, that similar check is used in vdagent_chr_recv_caps() (before
call qemu_clipboard_peer_register()), and also before
qemu_clipboard_peer_unregister() call in vdagent_disconnect() and in
vnc_disconnect_finish().

c3abdb2faf ui/gtk: graphic_hw_gl_flushed after closing dmabuf->fence_fd
The dmabuf often becomes invalid right after unblocking pipeline
and graphic_hw_gl_flushed in case a new scanout blob is submitted
because the dmabuf associated with the current guest scanout is
freed after swapping.

So both graphic_hw_gl_block and graphic_hw_gl_flushed should be
executed after closing fence_fd for the current dmabuf.

6b717a8d44 hw/misc/sifive_u_otp: Use IF_PFLASH for the OTP device instead of IF_NONE
Configuring a drive with "if=none" is meant for creation of a backend
only, it should not get automatically assigned to a device frontend.
Use "if=pflash" for the One-Time-Programmable device instead (like
it is e.g. also done for the efuse device in hw/arm/xlnx-zcu102.c).

Since the old way of configuring the device has already been published
with the previous QEMU versions, we cannot remove this immediately, but
have to deprecate it and support it for at least two more releases.

319e89cdc3 escc: update the R_SPEC register SPEC_ALLSENT bit when writing to W_TXCTRL1
The ESCC datasheet states that SPEC_ALLSENT is always set in sync mode and set
in async mode once all characters have cleared the transmitter. Since writes to
SERIAL_DATA use a synchronous chardev API, the guest can never see the state when
transmission is in progress so it is possible to set SPEC_ALLSENT in the
R_SPEC register unconditionally.

This fixes a hang when using the Sun PROM as it attempts to enumerate the
onboard serial devices, and a similar hang in OpenBSD SPARC32 where in both cases
the boot process will not proceed until SPEC_ALLSENT has been set after writing
to W_TXCTRL1.

c29cd47e82 escc: always set STATUS_TXEMPTY in R_STATUS on device reset
The "Transmit Interrupts and Transmit Buffer Empty Bit" section of the ESCC
datasheet states the following about the STATUS_TXEMPTY bit: "After a hardware
reset (including a hardware reset by software), or a channel reset, this bit
is set to 1".

Update escc_reset() to set the STATUS_TXEMPTY bit in the R_STATUS register
on device reset as described which fixes a regression whereby the Sun PROM
checks this bit early on startup and gets stuck in an infinite loop if it is
not set.

fbab8cc24d meson.build: Support ncurses on MacOS and OpenBSD
MacOS provides header files for curses 5.7 with support
for wide characters, but requires _XOPEN_SOURCE_EXTENDED=1
to activate that.

By default those old header files are used even if there
is a newer Homebrew installation of ncurses 6.2 available.

Change also the old macro definition of NCURSES_WIDECHAR
and set it to 1 like it is done in newer versions of
curses.h when _XOPEN_SOURCE_EXTENDED=1 is defined.

OpenBSD has the same version of ncurses and needs the same fix.

9fc6e86e8b hw/nvme: reattach subsystem namespaces on hotplug
With commit 5ffbaeed16 ("hw/nvme: fix controller hot unplugging")
namespaces get moved from the controller to the subsystem if one
is specified.
That keeps the namespaces alive after a controller hot-unplug, but
after a controller hotplug we have to reconnect the namespaces
from the subsystem to the controller.

While activating device in vmxnet3_acticate_device(), it does not
validate guest supplied configuration values against predefined
