Define the DEXCR and HDEXCR as special purpose registers.
Each register occupies two SPR indicies, one which can be read in an
unprivileged state and one which can be modified in the appropriate
priviliged state, however both indicies refer to the same underlying
value.
Note that the ISA uses the abbreviation UDEXCR in two different
contexts: the userspace DEXCR, the SPR index which can be read from
userspace (implemented in this patch), and the ultravisor DEXCR, the
equivalent register for the ultravisor state (not implemented).

Currently objects including "hw/ppc/spapr.h" are forced to be
target specific due to the inclusion of "vof.h" in "spapr.h".
"spapr.h" only uses a Vof pointer, so doesn't require the structure
declaration. The only place where Vof structure is accessed is in
spapr.c, so include "vof.h" there, and forward declare the structure
in "spapr.h".

Some SDHCI IP can be synthetized in various endianness:
https://github.com/u-boot/u-boot/blob/v2021.04/doc/README.fsl-esdhc
- CONFIG_SYS_FSL_ESDHC_BE
ESDHC IP is in big-endian mode. Accessing ESDHC registers can be
determined by ESDHC IP's endian mode or processor's endian mode.
Our current implementation is little-endian. In order to support
big endianness:
- Rename current MemoryRegionOps as sdhci_mmio_le_ops ('le')
- Add an 'endianness' property to SDHCIState (default little endian)
- Set the 'io_ops' field in realize() after checking the property
- Add the sdhci_mmio_be_ops (big-endian) MemoryRegionOps.

MAINTAINERS: downgrade PPC KVM/TCG CPUs and pSeries to 'Odd Fixes'
The maintainer is no longer being paid to maintain these components. All
maintainership work is being done in his personal time since the middle
of the 7.2 development cycle.
Change the status of PPC KVM CPUs, PPC TCG CPUs and the pSeries machine
to 'Odd Fixes', reflecting that the maintainer no longer has exclusive
time to dedicate to them. It'll also (hopefully) keep expectations under
check when/if these components are used in a customer product.

block/io: Check for replay-enabled in bdrv_drain_all_begin()
In commit da0bd74434 we refactored bdrv_drain_all_begin() to pull out
the non-polling part into bdrv_drain_all_begin_nopoll(). This change
broke record-and-replay, because the "return early if replay enabled"
check is now in the sub-function bdrv_drain_all_begin_nopoll(), and
so it only causes us to return from that function, and not from the
calling bdrv_drain_all_begin().
Fix the regression by checking whether replay is enabled in both
functions.
The breakage and fix can be tested via 'make check-avocado': the
tests/avocado/reverse_debugging.py:ReverseDebugging_X86_64.test_x86_64_pc
tests/avocado/reverse_debugging.py:ReverseDebugging_AArch64.test_aarch64_virt

hw/isa: enable TCO watchdog reboot pin strap by default
The TCO watchdog implementation default behaviour from POV of the
guest OS relies on the initial values for two I/O ports:
* TCO1_CNT == 0x0
Since bit 11 (TCO Timer Halt) is clear, the watchdog state
is considered to be initially running
* GCS == 0x20
Since bit 5 (No Reboot) is set, the watchdog will not trigger
when the timer expires
This is a safe default, because the No Reboot bit will prevent the
watchdog from triggering if the guest OS is unaware of its existance,
or is slow in configuring it. When a Linux guest initializes the TCO
watchdog, it will attempt to clear the "No Reboot" flag, and read the
value back. If the clear was honoured, the driver will treat this as
an indicator that the watchdog is functional and create the guest
watchdog device.
QEMU implements a second "no reboot" flag, however, via pin straps
which overrides the behaviour of the guest controlled "no reboot"
flag:
This second 'noreboot' pin was defaulted to high, which also inhibits
triggering of the requested watchdog actions, unless QEMU is launched
with the magic flag "-global ICH9-LPC.noreboot=false".
This is a bad default as we are exposing a watchdog to every guest OS
using the q35 machine type, but preventing it from actually doing what
it is designed to do. What is worse is that the guest OS and its apps
have no way to know that the watchdog is never going to fire, due to
this second 'noreboot' pin.
If a guest OS had no watchdog device at all, then apps whose operation
and/or data integrity relies on a watchdog can refuse to launch, and
alert the administrator of the problematic deployment. With Q35 machines
unconditionally exposing a watchdog though, apps will think their
deployment is correct but in fact have no protection at all.
This patch flips the default of the second 'no reboot' flag, so that
configured watchdog actions will be honoured out of the box for the
7.2 Q35 machine type onwards, if the guest enables use of the watchdog.

qga-win: choose the right libpcre version to include in MSI package
According to GLib changelog [1], since version 2.73.2 GLib is using
libpcre2 instead of libpcre. As a result, qemu-ga MSI installation
fails due to missing DLL when linked with the newer GLib.
This commit makes wixl to put the right libpcre version into the MSI
bundle: either libpcre-1.dll or libpcre2-8-0.dll, depending on the
present version of GLib.

qga: map GLib log levels to system levels
This patch translates GLib-specific log levels to system ones, so that
they may be used by both *nix syslog() (as a "priority" argument) and
Windows ReportEvent() (as a "wType" argument).
Currently the only codepath to write to "syslog" domain is slog()
function. However, this patch allows the interface to be extended.
Note that since slog() is using G_LOG_LEVEL_INFO level, its behaviour
doesn't change.

qga-win: add logging to Windows event log
This commit allows QGA to write to Windows event log using Win32 API's
ReportEvent() [1], much like syslog() under *nix guests.
In order to generate log message definitions we use a very basic message
text file [2], so that every QGA's message gets ID 1. The tools
"windmc" and "windres" respectively are used to generate ".rc" file and
COFF object file, and then the COFF file is linked into qemu-ga.exe.

pci: Fix silent truncation of pcie_aer_inject_error argument
PCI AER error status is 32 bit. The HMP command supports both
symbolic and numeric error status: anything that isn't a known
symbolic value is parsed as number with strtol(). Issues:
* Empty argument yields value zero.
* Range errors from strtol() are ignored, value is UINT32_MAX.
* Values not representable in uint32_t are silently truncated.
Fix to reject such input by switching to strtoui().

pci: Make query-pci stub consistent with the real one
QMP query-pci and HMP info pci can behave differently when there are
no PCI devices. They can report nothing, like this:
qemu-system-aarch64 -S -M spitz -display none -monitor stdio
QEMU 7.1.91 monitor - type 'help' for more information
(qemu) info pci
Or they can fail, like this:
qemu-system-microblaze -M petalogix-s3adsp1800 -display none -monitor stdio
QEMU 7.1.91 monitor - type 'help' for more information
(qemu) info pci
PCI devices not supported
They fail when none of the target's machines supports PCI, i.e. when
we're using qmp_query_pci() from hw/pci/pci-stub.c.
The error is not useful, and reporting nothing makes sense, so do that
in pci-stub.c, too.
Now qmp_query_pci() can't fail anymore. Drop the dead error handling
from hmp_info_pci().
