Merge tag 'kvm-x86-generic-6.13' of https://github.com/kvm-x86/linux into HEAD

KVM generic changes for 6.13

 - Rework kvm_vcpu_on_spin() to use a single for-loop instead of making two
   partial poasses over "all" vCPUs.  Opportunistically expand the comment
   to better explain the motivation and logic.

 - Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock instead
   of RCU, so that running a vCPU on a different task doesn't encounter
   long stalls due to having to wait for all CPUs become quiescent.
