--------------------------------
Commit 63042c58affc ("KVM: arm64: Add interface to support vCPU preempted check") introduced paravirt spinlock operations, as pv_lock_ops was exported via EXPORT_SYMBOL(), while the pv_ops structure containing the pv lock operations is exported via EXPORT_SYMBOL_GPL().
Change that by using EXPORT_SYMBOL(pv_ops) for arm/arm64, as with the x86 architecture changes, the following: https://lore.kernel.org/all/20181029150116.25372-1-jgross@suse.com/T/#u
