Here's the first ppc pull request for qemu-6.1. It has a wide variety
of stuff accumulated during the 6.0 freeze. Highlights are:
* Multi-phase reset cleanups for PAPR
* Preliminary cleanups towards allowing !CONFIG_TCG for the ppc target
* Cleanup of AIL logic and extension to POWER10
* Further improvements to handling of hot unplug failures on PAPR
* Allow much larger numbers of CPU on pseries
* Support for the H_SCM_HEALTH hypercall
* Add support for the Pegasos II board
* Substantial cleanup to hflag handling
* Assorted minor fixes and cleanups

Since cpu_check_irqs() doesn't reference to anything outside
of CPUSPARCState, it better belongs to the architectural code
in target/, rather than the hardware specific code in hw/.
Note: while we moved the trace events, we don't rename them.
Remark: this allows us to build the leon3 machine stand alone,
fixing this link failure (because cpu_check_irqs is defined in
hw/sparc/sun4m.c which is only built when CONFIG_SUN4M is selected):

When building without the leon3 machine, we get this link failure:

target/sparc/int32_helper.c:172: undefined reference to `leon3_irq_ack'
This is because the leon3_irq_ack() is declared in hw/sparc/leon3.c,
which is only build when CONFIG_LEON3 is selected.
Fix by moving the leon3_cache_control_int() / leon3_irq_manager()
(which are specific to the leon3 machine) to hw/sparc/leon3.c.
Move the trace events along (but don't rename them).
leon3_irq_ack() is now locally used, declare it static to reduce

We weren't recording MSR_GS in hflags, which means that BookE
memory accesses were essentially random vs Guest State.
Instead of adding this bit directly, record the completed mmu
indexes instead. This makes it obvious that we are recording
exactly the information that we need.
This also means that we can stop directly recording MSR_IR.

Copying flags directly from msr has drawbacks: (1) msr bits
mean different things per cpu, (2) msr has 64 bits on 64 cpus
while tb->flags has only 32 bits.
Create a enum to define these bits. Document the origin of each bit
and validate those bits that must match MSR. This fixes the
truncation of env->hflags to tb->flags, because we no longer
have hflags bits set above bit 31.
Most of the code in ppc_tr_init_disas_context is moved over to
hreg_compute_hflags. Some of it is simple extractions from msr,
some requires examining other cpu flags. Anything that is moved
becomes a simple extract from hflags in ppc_tr_init_disas_context.
Several existing bugs are left in ppc_tr_init_disas_context, where
additional changes are required -- to be addressed in future patches.

Opcodes accessing Coprocessor 0 are privileged.
Move the CP0 helpers to sysemu/ and simplify the #ifdef'ry.

Move helper_cache() to tcg/sysemu/special_helper.c.
The CACHE opcode is privileged and is not accessible in user
emulation. However we get a link failure when restricting the
symbol to sysemu. For now, add a stub helper to satisfy linking,
which abort if ever called.

Move the Special opcodes helpers to tcg/sysemu/special_helper.c.
Since mips_io_recompile_replay_branch() is set as
CPUClass::io_recompile_replay_branch handler in cpu.c,
we need to declare its prototype in "tcg-internal.h".

The 3 map_address() handlers are local to tlb_helper.c,
no need to have their prototype declared publically.

Move tlb_helper.c to the tcg/sysemu/ subdir, along with
the following 3 declarations to tcg-internal.h:
- cpu_mips_tlb_flush()
- cpu_mips_translate_address()
- r4k_invalidate_tlb()
Simplify tlb_helper.c #ifdef'ry because files in tcg/sysemu/
are only build when sysemu mode is configured.

mmu_init() is only required by TCG accelerator.
