Update SeaBIOS-hppa to version 7 which fixes a boot problem
with Debian-12 install CD images.
The problem with Debian-12 is, that the ramdisc got bigger
than what the firmware could load in one call to the LSI
scsi driver.

When the OS triggers a reboot, the reset helper function sends a
qemu_system_reset_request(SHUTDOWN_CAUSE_GUEST_RESET) together with an
EXCP_HLT exception to halt the CPUs.
So, at reboot when initializing the CPUs again, make sure to set all
instruction pointers to the firmware entry point, disable any interrupts,
disable data and instruction translations, enable PSW_Q bit and tell qemu
to unhalt (halted=0) the CPUs again.
This fixes the various reboot issues which were seen when rebooting a
Linux VM, including the case where even the monarch CPU has been virtually
halted from the OS (e.g. via "chcpu -d 0" inside the Linux VM).

The xkb official name for the Arabic keyboard layout is 'ara'.
However xkb has for at least the past 15 years also permitted it to
be named via the legacy synonym 'ar'. In xkeyboard-config 2.39 this
synoynm was removed, which breaks compilation of QEMU:

Make QEMU always ask for the 'ara' xkb layout, which should work on
both older and newer xkeyboard-config. We leave the QEMU name for
this keyboard layout as 'ar'; it is not the only one where our name
for it deviates from the xkb standard name.

We use __builtin_subcll() to do a 64-bit subtract with borrow-in and
borrow-out when the host compiler supports it. Unfortunately some
versions of Apple Clang have a bug in their implementation of this
intrinsic which means it returns the wrong value. The effect is that
a QEMU built with the affected compiler will hang when emulating x86
or m68k float80 division.
The upstream LLVM issue is:
https://github.com/llvm/llvm-project/issues/55253
The commit that introduced the bug apparently never made it into an
upstream LLVM release without the subsequent fix
fffb6e6afd
but unfortunately it did make it into Apple Clang 14.0, as shipped
in Xcode 14.3 (14.2 is reported to be OK). The Apple bug number is
FB12210478.
Add ifdefs to avoid use of __builtin_subcll() on Apple Clang version
14 or greater. There is not currently a version of Apple Clang which
has the bug fix -- when one appears we should be able to add an upper
bound to the ifdef condition so we can start using the builtin again.
We make the lower bound a conservative "any Apple clang with major
version 14 or greater" because the consequences of incorrectly
disabling the builtin when it would work are pretty small and the
consequences of not disabling it when we should are pretty bad.
Many thanks to those users who both reported this bug and also
did a lot of work in identifying the root cause; in particular
to Daniel Bertalan and osy.

The nrf51_timer has a free-running counter which we implement using
the pattern of using two fields (update_counter_ns, counter) to track
the last point at which we calculated the counter value, and the
counter value at that time. Then we can find the current counter
value by converting the difference in wall-clock time between then
and now to a tick count that we need to add to the counter value.
Unfortunately the nrf51_timer's implementation of this has a bug
which means it loses time every time update_counter() is called.
After updating s->counter it always sets s->update_counter_ns to
'now', even though the actual point when s->counter hit the new value
will be some point in the past (half a tick, say). In the worst case
(guest code in a tight loop reading the counter, icount mode) the
counter is continually queried less than a tick after it was last
read, so s->counter never advances but s->update_counter_ns does, and
the guest never makes forward progress.
The fix for this is to only advance update_counter_ns to the
timestamp of the last tick, not all the way to 'now'. (This is the
pattern used in hw/misc/mps2-fpgaio.c's counter.)

In commit 2c5fa0778c we fixed an endianness bug in the Allwinner
A10 PIC model; however in the process we introduced a regression.
This is because the old code was robust against the incoming 'level'
argument being something other than 0 or 1, whereas the new code was
not.
In particular, the allwinner-sdhost code treats its IRQ line
as 0-vs-non-0 rather than 0-vs-1, so when the SD controller
set its IRQ line for any reason other than transmit the
interrupt controller would ignore it. The observed effect
was a guest timeout when rebooting the guest kernel.
Handle level values other than 0 or 1, to restore the old
behaviour.

The LDG instruction loads the tag from a memory address (identified
by [Xn + offset]), and then merges that tag into the destination
register Xt. We implemented this correctly for the case when
allocation tags are enabled, but didn't get it right when ATA=0:
instead of merging the tag bits into Xt, we merged them into the
memory address [Xn + offset] and then set Xt to that.
Merge the tag bits into the old Xt value, as they should be.

The atomic memory operations are supposed to return the old memory
data value in the destination register. This value is not
sign-extended, even if the operation is the signed minimum or
maximum. (In the pseudocode for the instructions the returned data
value is passed to ZeroExtend() to create the value in the register.)
We got this wrong because we were doing a 32-to-64 zero extend on the
result for 8 and 16 bit data values, rather than the correct amount
of zero extension.
Fix the bug by using ext8u and ext16u for the MO_8 and MO_16 data
sizes rather than ext32u.

Some of the PMU hflags bits can go out of synch, for example a store to
MMCR0 with PMCjCE=1 fails to update hflags correctly and results in
hflags mismatch:
qemu: fatal: TCG hflags mismatch (current:0x2408003d rebuilt:0x240a003d)
This can be reproduced by running perf on a recent machine.
Some of the fragility here is the duplication of PMU hflags calculations.
This change consolidates that in a single place to update pmu-related
hflags, to be called after a well defined state changes.
The post-load PMU update is pulled out of the MSR update because it does
not depend on the MSR value.

The 9p protocol does not specifically define how server shall behave when
client tries to open a special file, however from security POV it does
make sense for 9p server to prohibit opening any special file on host side
in general. A sane Linux 9p client for instance would never attempt to
open a special file on host side, it would always handle those exclusively
on its guest side. A malicious client however could potentially escape
from the exported 9p tree by creating and opening a device file on host
side.
With QEMU this could only be exploited in the following unsafe setups:
- Running QEMU binary as root AND 9p 'local' fs driver AND 'passthrough'
security model.
or
- Using 9p 'proxy' fs driver (which is running its helper daemon as
root).
These setups were already discouraged for safety reasons before,
however for obvious reasons we are now tightening behaviour on this.

For M-profile, there is no guest-facing A-profile format FSR, but we
still use the env->exception.fsr field to pass fault information from
the point where a fault is raised to the code in
arm_v7m_cpu_do_interrupt() which interprets it and sets the M-profile
specific fault status registers. So it doesn't matter whether we
fill in env->exception.fsr in the short format or the LPAE format, as
long as both sides agree. As it happens arm_v7m_cpu_do_interrupt()
assumes short-form.
In compute_fsr_fsc() we weren't explicitly choosing short-form for
M-profile, but instead relied on it falling out in the wash because
arm_s1_regime_using_lpae_format() would be false. This was broken in
commit 452c67a4 when we added v8R support, because we said "PMSAv8 is
always LPAE format" (as it is for v8R), forgetting that we were
implicitly using this code path on M-profile. At that point we would
hit a g_assert_not_reached():

When passing --smp with a number lower than XLNX_ZYNQMP_NUM_APU_CPUS,
the expression (ms->smp.cpus - XLNX_ZYNQMP_NUM_APU_CPUS) will result
in a positive number as ms->smp.cpus is a unsigned int.
This will raise the following error afterwards, as Qemu will try to

When we receive a packet from the xilinx_axienet and then try to s2mem
through the xilinx_axidma, if the descriptor ring buffer is full in the
xilinx axidma driver, we’ll assert the DMASR.HALTED in the
function : stream_process_s2mem and return 0. In the end, we’ll be stuck in
an infinite loop in axienet_eth_rx_notify.
This patch checks the DMASR.HALTED state when we try to push data
from xilinx axi-enet to xilinx axi-dma. When the DMASR.HALTED is asserted,
we will not keep pushing the data and then prevent the infinte loop.

Windows sends an extra left control key up/down input event for
every right alt key up/down input event for keyboards with
international layout. Since commit 830473455f ("ui/sdl2: fix
handling of AltGr key on Windows") QEMU uses a Windows low level
keyboard hook procedure to reliably filter out the special left
control key and to grab the keyboard on Windows.
The SDL2 version 2.0.16 introduced its own Windows low level
keyboard hook procedure to grab the keyboard. Windows calls this
callback before the QEMU keyboard hook procedure. This disables
the special left control key filter when the keyboard is grabbed.
To fix the problem, disable the SDL2 Windows low level keyboard
hook procedure.

The gd_motion_event size has some calculations for the cursor position,
which also take into account things like different size of the
framebuffer compared to the window size.
The use of window size makes things more difficult though, as at least
in the case of Wayland includes the size of ui elements like a menu bar
at the top of the window. This leads to a wrong position calculation by
a few pixels.
Fix it by using the size of the widget, which already returns the size
of the actual space to render the framebuffer.

We cannot use the generic reentrancy guard in the LSI code, so
we have to manually prevent endless reentrancy here. The problematic
lsi_execute_script() function has already a way to detect whether
too many instructions have been executed - we just have to slightly
change the logic here that it also takes into account if the function
has been called too often in a reentrant way.
The code in fuzz-lsi53c895a-test.c has been taken from an earlier
patch by Mauro Matteo Cascella.

The bytes and packets counter registers are cleared on read.
Copying the "total counter" registers to the "good counter" registers has
side effects.
If the "total" register is never read by the OS, it only gets incremented.
This leads to exponential growth of the "good" register.
This commit increments the counters individually to avoid this.
