Some s390x userspace programs are confused when seeing a foreign
/proc/cpuinfo [1]. Add the emulation for s390x; follow the respective
kernel code structure where possible.
Output example:
vendor_id : IBM/S390
# processors: 12
bogomips per cpu: 13370.00

Coverity complains that perf_marker is never unmapped. Fix by unmapping

Both TYPE_KVM_I8254 and TYPE_I8254 have their own but same implementation of
the "iobase" property. The storage for the property already resides in
PITCommonState, so also move the property definition there.

There is no need to disable this useful compiler warning for
all versions of the SDL. Unfortunately, various versions are
buggy (beside SDL 2.0.8, the version 2.26.0 and 2.26.1 are
broken, too, see https://github.com/libsdl-org/SDL/issues/6619 ),
but we can use a simple compiler check to see whethe

PPC TCG now supports multi-threaded CPU configuration for non-hypervisor
state. This requires PIR and TIR be set, because that's how sibling thread
matching is done.
spapr's nested-HV capability does not currently coexist with SMT. This
is quite analogous to LPAR-per-core mode on real hardware whi

Doorbells in SMT need to coordinate msgsndp/msgclrp and DPDES access from
multiple threads that affect the same state.

On an address match, skip checking for default permissions and return error
based on access defined in PMP configuration.
v2 Changes:
o Removed goto to return in place when address matches
o Call pmp_hart_has_privs_default at the end of the loop

In qemu-user-s390x, /proc/cpuinfo contains:

processor 1: version = 00, identification = 40, machine = 8561
The highest nibble is supposed to contain the CPU address, but it's off
by 2 bits. Fix the shift va
