CVE-2024-26691

In the Linux kernel, the following vulnerability has been resolved: KVM:
arm64: Fix circular locking dependency The rule inside kvm enforces that
the vcpu->mutex is taken inside kvm->lock. The rule is violated by the
pkvm_create_hyp_vm() which acquires the kvm->lock while already holding the
vcpu->mutex lock from kvm_vcpu_ioctl(). Avoid the circular locking
dependency altogether by protecting the hyp vm handle with the config_lock,
much like we already do for other forms of VM-scoped data.
