This patch adds the necessary KVM specific code to allow KVM to support the CPU halting and kicking operations needed by the queue spinlock PV code. Two KVM guests of 20 CPU cores (2 nodes) were created for performance testing in one of the following three configurations: 1) Only 1 VM is active 2) Both VMs are active and they share the same 20 physical CPUs (200% overcommit) 3) Both VMs are

Hi Xiantao, Some more nit-picking, though some of this is a bit more important to fixup. Cheers, Jes > +typedef struct thash_data { Urgh! argh!
