Patch 1 changes to check guest memfd CAP on VM instance.

Patch 2 is a fix for KVM_SET_USER_MEMORY_REGION2.

Patch 3 is an enhancement for guest_memfd_offset.

---
Changes in v2:
- Collect R-B tags;
- Use {} to zero out the struct instead of memset() in patch2;
- Initialize guest_memfd_offset at the original source in patch3;

Xiaoyao Li (3):
  accel/kvm: Switch to check KVM_CAP_GUEST_MEMFD and
    KVM_CAP_USER_MEMORY2 on VM
  accel/kvm: Zero out mem explicitly in kvm_set_user_memory_region()
  accel/kvm: Set guest_memfd_offset to non-zero value only when
    guest_memfd is valid
