far call using the CALL or JMP instruction, was always going from kernel

KVM: Dynamic sized kvm memslots array
Zhiyi reported an infinite loop issue in VFIO use case. The cause of that
was a separate discussion, however during that I found a regression of
dirty sync slowness when profiling.
Each KVMMemoryListerner maintains an array of kvm memslots. Currently it's
statically allocated to be the max supported by the kernel. However after
Linux commit
4fc096a99e ("KVM: Raise the maximum number of user memslots"),
the max supported memslots reported now grows to some number large enough
so that it may not be wise to always statically allocate with the max
reported.
What's worse, QEMU kvm code still walks all the allocated memslots entries
to do any form of lookups. It can drastically slow down all memslot
operations because each of such loop can run over 32K times on the new
kernels.
Fix this issue by making the memslots to be allocated dynamically.
Here the initial size was set to 16 because it should cover the basic VM
usages, so that the hope is the majority VM use case may not even need to
grow at all (e.g. if one starts a VM with ./qemu-system-x86_64 by default
it'll consume 9 memslots), however not too large to waste memory.
There can also be even better way to address this, but so far this is the
simplest and should be already better even than before we grow the max
supported memslots. For example, in the case of above issue when VFIO was
attached on a 32GB system, there are only ~10 memslots used. So it could
be good enough as of now.
In the above VFIO context, measurement shows that the precopy dirty sync
shrinked from ~86ms to ~3ms after this patch applied. It should also apply
to any KVM enabled VM even without VFIO.
NOTE: we don't have a FIXES tag for this patch because there's no real
commit that regressed this in QEMU. Such behavior existed for a long time,
but only start to be a problem when the kernel reports very large
nr_slots_max value. However that's pretty common now (the kernel change
was merged in 2021) so we attached cc:stable because we'll want this change
to be backported to stable branches.

There are now relatively few unconverted opcodes in translate.c (there
are 13 of them including 8 for x87), and all of them have the same
format with a mod/rm byte and no immediate. A good next step is
to remove the early bail out to disas_insn_x87/disas_insn_old,
instead giving these legacy translator functions the same prototype
as the other gen_* functions.
To do this, the X86DecodeInsn can be passed down to the places that
used to fetch address bytes from the instruction stream. To make
sure that everything is done cleanly, the CPUX86State* argument is
removed.
As part of the unification, the gen_lea_modrm() name is now free,
so rename gen_load_ea() to gen_lea_modrm(). This is as good a name
and it makes the changes to translate.c easier to review.

target/i386: Make sure SynIC state is really updated before KVM_RUN
'hyperv_synic' test from KVM unittests was observed to be flaky on certain
hardware (hangs sometimes). Debugging shows that the problem happens in
hyperv_sint_route_new() when the test tries to set up a new SynIC
route. The function bails out on:
if (!synic->sctl_enabled) {

synic_update() (called from async_synic_update()) happens after the SINT
setup attempt and not before. Apparently, the comment before
async_safe_run_on_cpu() in kvm_hv_handle_exit() does not correctly describe
the guarantees async_safe_run_on_cpu() gives. In particular, async worked
added to a CPU is actually processed from qemu_wait_io_event() which is not
always called before KVM_RUN, i.e. kvm_cpu_exec() checks whether an exit
request is pending for a CPU and if not, keeps running the vCPU until it
meets an exit it can't handle internally. Hyper-V specific MSR writes are
not automatically trigger an exit.
Fix the issue by simply raising an exit request for the vCPU where SynIC
update was queued. This is not a performance critical path as SynIC state
does not get updated so often (and async_safe_run_on_cpu() is a big hammer
anyways).

target/i386: Exclude 'hv-syndbg' from 'hv-passthrough'
Windows with Hyper-V role enabled doesn't boot with 'hv-passthrough' when
no debugger is configured, this significantly limits the usefulness of the
feature as there's no support for subtracting Hyper-V features from CPU
flags at this moment (e.g. "-cpu host,hv-passthrough,-hv-syndbg" does not
work). While this is also theoretically fixable, 'hv-syndbg' is likely
very special and unneeded in the default set. Genuine Hyper-V doesn't seem
to enable it either.
Introduce 'skip_passthrough' flag to 'kvm_hyperv_properties' and use it as
one-off to skip 'hv-syndbg' when enabling features in 'hv-passthrough'
mode. Note, "-cpu host,hv-passthrough,hv-syndbg" can still be used if
needed.
As both 'hv-passthrough' and 'hv-syndbg' are debug features, the change
should not have any effect on production environments.

target/i386: Fix conditional CONFIG_SYNDBG enablement
Putting HYPERV_FEAT_SYNDBG entry under "#ifdef CONFIG_SYNDBG" in
'kvm_hyperv_properties' array is wrong: as HYPERV_FEAT_SYNDBG is not
the highest feature number, the result is an empty (zeroed) entry in
the array (and not a skipped entry!). hyperv_feature_supported() is
designed to check that all CPUID bits are set but for a zeroed
feature in 'kvm_hyperv_properties' it returns 'true' so QEMU considers
HYPERV_FEAT_SYNDBG as always supported, regardless of whether KVM host
actually supports it.
To fix the issue, leave HYPERV_FEAT_SYNDBG's definition in
'kvm_hyperv_properties' array, there's nothing wrong in having it defined
even when 'CONFIG_SYNDBG' is not set. Instead, put "hv-syndbg" CPU property
under '#ifdef CONFIG_SYNDBG' to alter the existing behavior when the flag
is silently skipped in !CONFIG_SYNDBG builds.
Leave an 'assert' sentinel in hyperv_feature_supported() making sure there
are no 'holes' or improperly defined features in 'kvm_hyperv_properties'.

vl.c: Remove pxa2xx-specific -portrait and -rotate options
The ``-portrait`` and ``-rotate`` options were documented as only
working with the PXA LCD device, and all the machine types using
that display device were removed in 9.2.
These options were intended to simulate a mobile device being
rotated by the user, and had three effects:
* the display output was rotated by 90, 180 or 270 degrees
(implemented in the PXA display device models)
* the mouse/trackpad input was rotated the opposite way
(implemented in generic code)
* the machine model would signal to the guest about its
orientation
(implemented by e.g. the spitz machine model)
Of these three things, the input-rotation was coded without being
restricted to boards which supported the full set of device-rotation
handling, so in theory the options were usable on other machine
models with odd effects (rotating input but not display output). But
this was never intended or documented behaviour, so we can reasonably
drop these command line arguments without a formal deprecate-and-drop
cycle for them.
Remove the options, and their implementation and documentation.
Describe the removal in removed-features.rst.

The only PCMCIA subsystem was the PXA2xx SoC and the machines

we have a few machine types which have PCMCIA (e.g. kzm,
the strongarm machines, sh4's sh7750), none of those machines

we can always resurrect it.

The MAX7310 GPIO controller was used only by the XScale-based Zaurus

Because this device is an I2C device, in theory it could be created
by users on the command line for boards with a different I2c
controller, but we don't believe users are doing this -- it would be
impossible on the command line to connect up the GPIO inputs/outputs.
The only example a web search produces for "device max7310" is a user
trying to create this because they didn't realize that there was no
way to manipulate the GPIO lines.

hw/adc: Remove MAX111X device
The MAX111X ADC device was used only by the XScale-based
Zaurus machine types. Now they have all been removed, we can
drop this device model too.
Because this device is an SSI device, in theory it could be created
by users on the command line for boards with a different SSI
controller, but we don't believe users are doing this -- it would be
impossible on the command line to connect up the GPIO inputs which
correspond to ADC inputs, or the GPIO output which is an interrupt
line. The only example a web search produces for "device max1111" or
"device max1110" is our own bug report
https://gitlab.com/qemu-project/qemu/-/issues/2228
where it's used as an example of a bogus command that causes an
assertion in an aspeed machine type that wasn't expecting anything
other than flash devices on its SMC bus.

include: Move QemuLockCnt APIs to their own header
Currently the QemuLockCnt data structure and associated functions are
in the include/qemu/thread.h header. Move them to their own
qemu/lockcnt.h. The main reason for doing this is that it means we
can autogenerate the documentation comments into the docs/devel
documentation.
The copyright/author in the new header is drawn from lockcnt.c,
since the header changes were added in the same commit as
lockcnt.c; since neither thread.h nor lockcnt.c state an explicit
license, the standard default of GPL-2-or-later applies.
We include the new header (and the .c file, which was accidentally
omitted previously) in the "RCU" part of MAINTAINERS, since that
is where the lockcnt.rst documentation is categorized.

hw/char/pl011: Use correct masks for IBRD and FBRD
In commit
b88cfee90268cad we defined masks for the IBRD and FBRD
integer and fractional baud rate divider registers, to prevent the
guest from writing invalid values which could cause division-by-zero.
Unfortunately we got the mask values the wrong way around: the FBRD
register is six bits and the IBRD register is 16 bits, not
vice-versa.
You would only run into this bug if you programmed the UART to a baud
rate of less than 9600, because for 9600 baud and above the IBRD
value will fit into 6 bits, as per the table in
https://developer.arm.com/documentation/ddi0183/g/programmers-model/register-descriptions/fractional-baud-rate-register--uartfbrd
The only visible effects would be that the value read back from
the register by the guest would be truncated, and we would
print an incorrect baud rate in the debug logs.

This patch implements Allwinner A10 SPI controller emulation.
Only master-mode functionality is implemented.
Since U-Boot and Linux SPI drivers for Allwinner A10 perform only
byte-wide CPU access (no DMA) to the transmit and receive registers of
the peripheral, the emulated controller does not implement DMA control,
and supports only byte-wide access to transmit and receive registers
(half-word and word accesses will be treated as byte accesses).
