These two patches (one for Linux, one for Xen) allow PVHVM guests to use the per-cpu VCPU mechanism after migration. Currently when an PVHVM guest migrates all the per-cpu information is lost and we fallback on the shared_info structure. This is regardless if the HVM guest has 2 or 128 CPUs. Since the structure has an array for only 32 CPUs that means if we are to migrate a PVHVM guest - we can only do it up to 32 CPUs. These patches fix it and allow more than 32 VCPUs to be migrated with PVHVM Linux guests.
