1817af991c HPPA64-PATCHES-for-8.2
Two patches for 8.2.
 
 The SHRPD patch fixes a real translation bug which then allows to boot
 the 64-bit Linux kernels of the Debian-11 and Debian-12 installation CDs.
 
 The second patch adds the instruction byte sequence to the
 assembly log. This is not an actual bug fix, but it's important since
 it helps a lot when trying to fix qemu translation bugs on hppa.

d12a91e0ba target/s390x/arch_dump: Add arch cleanup function for PV dumps
PV dumps block vcpu runs until dump end is reached. If there's an
error between PV dump init and PV dump end the vm will never be able
to run again. One example of such an error is insufficient disk space
for the dump file.

Let's add a cleanup function that tries to do a dump end. The dump
completion data is discarded but there's no point in writing it to a
file anyway if there's a possibility that other PV dump data is
missing.

f6e8d1ef05 target/arm/tcg: enable PMU feature for Cortex-A8 and A9
According to the technical reference manual, the Cortex-A9
has a Perfomance Unit Monitor (PMU):
https://developer.arm.com/documentation/100511/0401/performance-monitoring-unit/about-the-performance-monitoring-unit
The Cortex-A8 does also.

We already already define the PMU registers when emulating the
Cortex-A8 and Cortex-A9, because we put them in v7_cp_reginfo[]
rather than guarding them behind ARM_FEATURE_PMU.  So the only thing
that setting the feature bit changes is that the registers actually
do something.

Enable ARM_FEATURE_PMU for Cortex-A8 and Cortex-A9, to avoid
this anomaly.

(The A8 and A9 PMU predates the standardisation of ID_DFR0.PerfMon,
so the field there is 0, but the PMU is still present.)

4d044472ab target/arm: Correct MTE tag checking for reverse-copy MOPS
When we are doing a FEAT_MOPS copy that must be performed backwards,
we call mte_mops_probe_rev(), passing it the address of the last byte
in the region we are probing.  However, allocation_tag_mem_probe()
wants the address of the first byte to get the tag memory for.
Because we passed it (ptr, size) we could incorrectly trip the
allocation_tag_mem_probe() check for "does this access run across to
the following page", and if that following page happened not to be
valid then we would assert.

We know we will always be only dealing with a single page because the
code that calls mte_mops_probe_rev() ensures that.  We could make
mte_mops_probe_rev() pass 'ptr - (size - 1)' to
allocation_tag_mem_probe(), but then we would have to adjust the
returned 'mem' pointer to get back to the tag RAM for the last byte
of the region.  It's simpler to just pass in a size of 1 byte,
because we know that allocation_tag_mem_probe() in pure-probe
single-page mode doesn't care about the size.

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.
