fa71b4f84f target/hppa: Reduce TARGET_PHYS_ADDR_SPACE_BITS to 40
This is the value that is supported by both PA-8500 and Astro.
If we support a larger address space than expected, we trip up
software that did not fill in all of the page table bits,
expecting them to be ignored.

451d993d58 target/hppa: Replace MMU_PHYS_IDX with MMU_ABS_IDX, MMU_ABS_W_IDX
Align the language with pa2.0, separating absolute and physical.
The translation from absolute to physical depends on PSW.W, and
we prefer not to flush between changes, therefore use 2 mmu_idx.

2a23f0f118 target/hppa: Fix possible overflow in TLB size calculation
Coverty found that the shift of TARGET_PAGE_SIZE (32-bit type) might
overflow.  Fix it by casting TARGET_PAGE_SIZE to a 64-bit type before
doing the shift (CID 1523902 and CID 1523908).

The system mask is a restricted subset of the psw, with only

3e19fbc0c5 target/s390x/cpu topology: Fix ordering and creation of TLEs
In case of horizontal polarization entitlement has no effect on
ordering.
Moreover, since the comparison is used to insert CPUs at the correct
position in the TLE list, this affects the creation of TLEs and now
correctly collapses horizontally polarized CPUs into one TLE.

bea402482a target/s390x: Fix LAALG not updating cc_src
LAALG uses op_laa() and wout_addu64(). The latter expects cc_src to be
set, but the former does not do it. This can lead to assertion failures
if something sets cc_src to neither 0 nor 1 before.

Fix by introducing op_laa_addu64(), which sets cc_src, and using it for
LAALG.

958ac3c42b system/cpus: Fix CPUState.nr_cores' calculation
From CPUState.nr_cores' comment, it represents "number of cores within
this CPU package".

After 003f230e37 ("machine: Tweak the order of topology members in
struct CpuTopology"), the meaning of smp.cores changed to "the number of
cores in one die", but this commit missed to change CPUState.nr_cores'
calculation, so that CPUState.nr_cores became wrong and now it
misses to consider numbers of clusters and dies.

At present, only i386 is using CPUState.nr_cores.

But as for i386, which supports die level, the uses of CPUState.nr_cores
are very confusing:

Early uses are based on the meaning of "cores per package" (before die
is introduced into i386), and later uses are based on "cores per die"
(after die's introduction).

This difference is due to that commit a94e142899 ("target/i386: Add
CPUID.1F generation support for multi-dies PCMachine") misunderstood
that CPUState.nr_cores means "cores per die" when calculated
CPUID.1FH.01H:EBX. After that, the changes in i386 all followed this
wrong understanding.

With the influence of 003f230e37 and a94e142899, for i386 currently
the result of CPUState.nr_cores is "cores per die", thus the original
uses of CPUState.cores based on the meaning of "cores per package" are
wrong when multiple dies exist:
1. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.01H:EBX[bits 23:16] is
   incorrect because it expects "cpus per package" but now the
   result is "cpus per die".
2. In cpu_x86_cpuid() of target/i386/cpu.c, for all leaves of CPUID.04H:
   EAX[bits 31:26] is incorrect because they expect "cpus per package"
   but now the result is "cpus per die". The error not only impacts the
   EAX calculation in cache_info_passthrough case, but also impacts other
   cases of setting cache topology for Intel CPU according to cpu
   topology (specifically, the incoming parameter "num_cores" expects
   "cores per package" in encode_cache_cpuid4()).
3. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.0BH.01H:EBX[bits
   15:00] is incorrect because the EBX of 0BH.01H (core level) expects
   "cpus per package", which may be different with 1FH.01H (The reason
   is 1FH can support more levels. For QEMU, 1FH also supports die,
   1FH.01H:EBX[bits 15:00] expects "cpus per die").
4. In cpu_x86_cpuid() of target/i386/cpu.c, when CPUID.80000001H is
   calculated, here "cpus per package" is expected to be checked, but in
   fact, now it checks "cpus per die". Though "cpus per die" also works
   for this code logic, this isn't consistent with AMD's APM.
5. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.80000008H:ECX expects
   "cpus per package" but it obtains "cpus per die".
6. In simulate_rdmsr() of target/i386/hvf/x86_emu.c, in
   kvm_rdmsr_core_thread_count() of target/i386/kvm/kvm.c, and in
   helper_rdmsr() of target/i386/tcg/sysemu/misc_helper.c,
   MSR_CORE_THREAD_COUNT expects "cpus per package" and "cores per
   package", but in these functions, it obtains "cpus per die" and
   "cores per die".

On the other hand, these uses are correct now (they are added in/after
a94e142899):
1. In cpu_x86_cpuid() of target/i386/cpu.c, topo_info.cores_per_die
   meets the actual meaning of CPUState.nr_cores ("cores per die").
2. In cpu_x86_cpuid() of target/i386/cpu.c, vcpus_per_socket (in CPUID.
   04H's calculation) considers number of dies, so it's correct.
3. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.1FH.01H:EBX[bits
   15:00] needs "cpus per die" and it gets the correct result, and
   CPUID.1FH.02H:EBX[bits 15:00] gets correct "cpus per package".

When CPUState.nr_cores is correctly changed to "cores per package" again
, the above errors will be fixed without extra work, but the "currently"
correct cases will go wrong and need special handling to pass correct
"cpus/cores per die" they want.

Fix CPUState.nr_cores' calculation to fit the original meaning "cores
per package", as well as changing calculation of topo_info.cores_per_die,
vcpus_per_socket and CPUID.1FH.

Fixes: a94e142899 ("target/i386: Add CPUID.1F generation support for multi-dies PCMachine")
Fixes: 003f230e37 ("machine: Tweak the order of topology members in struct CpuTopology")

2c6822cd59 target/s390x: Use env_archcpu() in handle_diag_308()
When CPUArchState* is available (here CPUS390XState*), we
can use the fast env_archcpu() macro to get ArchCPU* (here
S390CPU*). The QOM cast S390_CPU() macro will be slower when
building with --enable-qom-cast-debug.

edf67fb4c2 target/riscv: Use env_archcpu() in [check_]nanbox()
When CPUArchState* is available (here CPURISCVState*), we
can use the fast env_archcpu() macro to get ArchCPU* (here
RISCVCPU*). The QOM cast RISCV_CPU() macro will be slower
when building with --enable-qom-cast-debug.
