cpu-common: use atomic access for interrupt_request
Writes to interrupt_request used non-atomic accesses, but there are a
few cases where the access was not protected by the BQL. Now that
there is a full set of helpers, it's easier to guarantee that
interrupt_request accesses are fully atomic, so just drop the
requirement instead of fixing them.

accel: use store_release/load_acquire for cross-thread exit_request
Reads and writes cpu->exit_request do not use a load-acquire/store-release
pair right now, but this means that cpu_exit() may not write cpu->exit_request
after any flags that are read by the vCPU thread.
Probably everything is protected one way or the other by the BQL, because
cpu->exit_request leads to the slow path, where the CPU thread often takes
the BQL (for example, to go to sleep by waiting on the BQL-protected
cpu->halt_cond); but it's not clear, so use load-acquire/store-release
consistently.

Round-robin TCG is calling into cpu_exit() directly. In preparation
for making cpu_exit() usable from all accelerators, define a generic
thread-kick function for TCG which is used directly in the multi-threaded
case, and through CPU_FOREACH in the round-robin case.
Use it also for user-mode emulation, and take the occasion to move
the implementation to accel/tcg/user-exec.c.

accel/tcg: inline cpu_exit()
Right now, cpu_exit() is not usable from all accelerators because it
includes a TCG-specific thread kick. In fact, cpu_exit() doubles as
the TCG thread-kick via tcg_kick_vcpu_thread().
In preparation for changing that, inline cpu_exit() into
tcg_kick_vcpu_thread(). The direction of the calls can then be
reversed, with an accelerator-independent cpu_exit() calling into
qemu_vcpu_kick() rather than the opposite.

cpus: clear exit_request in qemu_process_cpu_events
Make the code common to all accelerators: after seeing cpu->exit_request
set to true, accelerator code needs to reach qemu_process_cpu_events_common().
So for the common cases where they use qemu_process_cpu_events(), go ahead and
clear it in there. Note that the cheap qatomic_set() is enough because
at this point the thread has taken the BQL; qatomic_set_mb() is not needed.
In particular, this is the ordering of the communication between
I/O and vCPU threads is always the same.
In the I/O thread:
(a) store other memory locations that will be checked if cpu->exit_request
or cpu->interrupt_request is 1 (for example cpu->stop or cpu->work_list
for cpu->exit_request)
(b) cpu_exit(): store-release cpu->exit_request, or
(b) cpu_interrupt(): store-release cpu->interrupt_request
>>> at this point, cpu->halt_cond is broadcast and the BQL released
(c) do the accelerator-specific kick (e.g. write icount_decr for TCG,
pthread_kill for KVM, etc.)
In the vCPU thread instead the opposite order is respected:
(c) the accelerator's execution loop exits thanks to the kick
(b) then the inner execution loop checks cpu->interrupt_request
and cpu->exit_request. If needed cpu->interrupt_request is
converted into cpu->exit_request when work is needed outside
the execution loop.
(a) then the other memory locations are checked. Some may need to
be read under the BQL, but the vCPU thread may also take other
locks (e.g. for queued work items) or none at all.
qatomic_set_mb() would only be needed if the halt sleep was done
outside the BQL (though in that case, cpu->exit_request probably
would be replaced by a QemuEvent or something like that).

rust: add qdev Device derive macro
Add derive macro for declaring qdev properties directly above the field
definitions. To do this, we split DeviceImpl::properties method on a
separate trait so we can implement only that part in the derive macro
expansion (we cannot partially implement the DeviceImpl trait).
Adding a `property` attribute above the field declaration will generate
a `qemu_api::bindings::Property` array member in the device's property
list.

rust: vmstate: convert to use builder pattern
Similar to MemoryRegionOps, the builder pattern has two advantages:
1) it makes it possible to build a VMStateDescription that knows which
types it will be invoked on; 2) it provides a way to wrap the callbacks
and let devices avoid "unsafe".
Unfortunately, building a static VMStateDescription requires the
builder methods to be "const", and because the VMStateFields are
*also* static, this requires const_refs_static. So this requires
Rust 1.83.0.

rust: vmstate: use const_refs_to_static
The VMStateDescriptionBuilder already needs const_refs_static, so
use it to remove the need for vmstate_clock! and vmstate_struct!,
as well as to simplify the implementation for scalars.
If the consts in the VMState trait can reference to static
VMStateDescription, scalars do not need the info_enum_to_ref!
indirection and structs can implement the VMState trait themselves.

rust: qdev: const_refs_to_static
Now that const_refs_static can be assumed, convert the members of
the DeviceImpl trait from functions to constants. This lets the
compiler know that they have a 'static lifetime, and removes the
need for the weird "Box::leak()".

rust: repurpose qemu_api -> tests
The crate purpose is only to provide integration tests at this point,
that can't easily be moved to a specific crate.
It's also often a good practice to have a single integration test crate
(see for ex https://github.com/rust-lang/cargo/issues/4867)
Drop README.md, use docs/devel/rust.rst instead.

i386/cpu: Enable SMM cpu address space under KVM
Kirill Martynov reported assertation in cpu_asidx_from_attrs() being hit
when x86_cpu_dump_state() is called to dump the CPU state[*]. It happens
when the CPU is in SMM and KVM emulation failure due to misbehaving
guest.
The root cause is that QEMU i386 never enables the SMM address space for
cpu since KVM SMM support has been added.
Enable the SMM cpu address space under KVM when the SMM is enabled for
the x86machine.

1fc: 66 ba 10 05 mov $0x510,%dx
We can see that the instruction at 0x1e3 is a far jmp through the GDT.
However, the GDT is not 8 byte aligned, the base is 0xc02b4.
Intel processors follow the LOCK semantics to set the accessed flag of the
segment descriptor when loading a segment descriptor. If the the segment
descriptor crosses two cache line, it causes split lock.
Fix it by aligning the GDT on 8 bytes, so that segment descriptor cannot
span two cache lines.

x86_machine_is_smm_enabled() checks the KVM_CAP_X86_SMM for KVM
case. No need to check KVM_CAP_X86_SMM in kvm_arch_init().
So just drop the check of KVM_CAP_X86_SMM to simplify the code.

It returns more accruate result on checking KVM_CAP_GUEST_MEMFD and

accel/kvm: Zero out mem explicitly in kvm_set_user_memory_region()
Zero out the entire mem explicitly before it's used, to ensure the unused
feilds (pad1, pad2) are all zeros. Otherwise, it might cause problem when
the pad fields are extended by future KVM.

accel/kvm: Set guest_memfd_offset to non-zero value only when guest_memfd is
valid
Current QEMU unconditionally sets the guest_memfd_offset of KVMSlot in
kvm_set_phys_mem(), which leads to the trace of kvm_set_user_memory looks:
kvm_set_user_memory AddrSpace#0 Slot#4 flags=0x2 gpa=0xe0000 size=0x20000
ua=0x7f5840de0000 guest_memfd=-1 guest_memfd_offset=0x3e0000 ret=0
It's confusing that the guest_memfd_offset has a non-zero value while
the guest_memfd is invalid (-1).
Change to only set guest_memfd_offset when guest_memfd is valid and
leave it as 0 when no valid guest_memfd.

hw/loongarch/virt: Add BSP support with aux boot code
If system boots directly from Linux kernel, BSP core jumps to kernel
entry of Linux kernel image and other APs jump to aux boot code. Instead
BSP and APs can all jump to aux boot code like UEFI bios.
With aux boot code, BSP core is judged from physical cpu id, whose
cpu id is 0. With BSP core, load data to register A0-A2 and PC.

interface with hot-added CPU should be registered. Otherwise there
will be problem if system reboots after cpu is hot-added.
Now register reset interface with CPU plug callback, so that all
cold/hot added CPUs let their reset interface registered. And remove
reset interface with CPU unplug callback.
