fb1856cb9b hw/isa/lpc_ich9: Remove redundant ich9_lpc_reset() invocation
ich9_lpc_reset() is the dc->reset callback which is called
automatically. No need to call it explicitly during k->realize.

20fe3af24f hw/isa/lpc_ich9: Connect PM stuff to LPC internally
Make TYPE_ICH9_LPC_DEVICE more self-contained by moving the call to
ich9_lpc_pm_init() from board code to its realize function. In order
to propagate x86_machine_is_smm_enabled(), introduce an "smm-enabled"
property like we have in piix4.

5b5968c477 replay: Extract core API to 'exec/replay-core.h'
replay API is used deeply within TCG common code (common to user
and system emulation). Unfortunately "sysemu/replay.h" requires
some QAPI headers for few system-specific declarations, example:

  void replay_input_event(QemuConsole *src, InputEvent *evt);

Since commit c2651c0eaa ("qapi/meson: Restrict UI module to system
emulation and tools") the QAPI header defining the InputEvent is
not generated anymore.
To keep it simple, extract the 'core' replay prototypes to a new
"exec/replay-core.h" header which we include in the TCG code that
doesn't need the rest of the replay API.

b5c6a3c1df target/i386: Remove x86_cpu_dump_local_apic_state() dead stub
x86_cpu_dump_local_apic_state() is called from monitor.c which
is only compiled for system emulation since commit bf95728400
("monitor: remove target-specific code from monitor.c").

Interestingly this stub was added few weeks later in commit
1f871d49e3 ("hmp: added local apic dump state") and was not
necessary by that time.

55b5b8e928 gdbstub: Use vaddr type for generic insert/remove_breakpoint() API
Both insert/remove_breakpoint() handlers are used in system and
user emulation. We can not use the 'hwaddr' type on user emulation,
we have to use 'vaddr' which is defined as "wide enough to contain
any #target_ulong virtual address".

gdbstub.c doesn't require to include "exec/hwaddr.h" anymore.

7eb061b06e i386: Add new CPU model SapphireRapids
The new CPU model mostly inherits features from Icelake-Server, while
adding new features:
 - AMX (Advance Matrix eXtensions)
 - Bus Lock Debug Exception
and new instructions:
 - AVX VNNI (Vector Neural Network Instruction):
    - VPDPBUS: Multiply and Add Unsigned and Signed Bytes
    - VPDPBUSDS: Multiply and Add Unsigned and Signed Bytes with Saturation
    - VPDPWSSD: Multiply and Add Signed Word Integers
    - VPDPWSSDS: Multiply and Add Signed Integers with Saturation
 - FP16: Replicates existing AVX512 computational SP (FP32) instructions
   using FP16 instead of FP32 for ~2X performance gain
 - SERIALIZE: Provide software with a simple way to force the processor to
   complete all modifications, faster, allowed in all privilege levels and
   not causing an unconditional VM exit
 - TSX Suspend Load Address Tracking: Allows programmers to choose which
   memory accesses do not need to be tracked in the TSX read set
 - AVX512_BF16: Vector Neural Network Instructions supporting BFLOAT16
   inputs and conversion instructions from IEEE single precision
 - fast zero-length MOVSB (KVM doesn't support yet)
 - fast short STOSB (KVM doesn't support yet)
 - fast short CMPSB, SCASB (KVM doesn't support yet)

Features that may be added in future versions:
 - CET (virtualization support hasn't been merged)

3023c9b4d1 target/i386: KVM: allow fast string operations if host supports them
These are just a flag that documents the performance characteristic of
an instruction; it needs no hypervisor support.  So include them even
if KVM does not show them.  In particular, FZRM/FSRS/FSRC have only
been added very recently, but they are available on Sapphire Rapids
processors.

These are three more markers for string operation optimizations.
They can all be added to TCG, whose string operations are more or
less as fast as they can be for short lengths.
