Hi,

QEMU 7.2.0 when run on 32-bit x86 architecture fails with:

  i586$ qemu-system-i386 -enable-kvm
  qemu-system-i386: Could not install MSR_CORE_THREAD_COUNT handler: Success
  i586$ qemu-system-x86_64 -enable-kvm
  qemu-system-x86_64: Could not install MSR_CORE_THREAD_COUNT handler: Success

Minimal reproducer is `qemu-system-i386 -enable-kvm'. And this only
happens on x86 (linux32 personality and binaries on x86_64 host):

  i586$ file /usr/bin/qemu-system-i386
  /usr/bin/qemu-system-i386: ELF 32-bit LSB pie executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, BuildID[sha1]=0ba1d953bcb7a691014255954f060ff404c8df90, for GNU/Linux 3.2.0, stripped
  i586$ /usr/bin/qemu-system-i386 --version
